| FTP Passive Data Connection Not Bound to the Authenticated Control Peer |
| `gx_binres_theme_load()` sizes its theme buffer for the theme it was asked for, and allocates it even when the resource holds no theme with that id. A theme id at or past the theme count declared by the resource gets a buffer of zero bytes. The load pass then walks past the end of the theme table, takes whatever follows as a theme header, and writes a `GX_THEME` and its tables into that zero-byte buffer. |
| Mounting an attacker-controlled NAND flash image (`lx_nand_flash_open()`) triggers an unbounded out-of-bounds heap **write** in LevelX's NAND flash-translation-layer metadata parser that overwrites a driver function pointer in the control block, giving a demonstrated control-flow hijack — RIP set to a full 8-byte attacker-chosen value (register-verified). Two accompanying OOB reads. All reproduced verbatim under ASan at HEAD `9f1cfdc`. (The affected metadata-parser header states "Some portions generated by Copilot (Sonnet 4.6)" — an AI-generated parser with an unchecked on-flash count.) |
| A DHCP server, or anyone on the LAN who answers a DISCOVER first, can make the client read about a
kilobyte past the end of the received message.
The option walk keeps a pointer and an offset in step, and the only bound check uses the offset:
```c
/* addons/dhcp/nxd_dhcp_client.c:7538, 7572 */
while (i < length - 1)
{
...
size = *(++data); /* data moves 1: type -> length byte */
data += size + 1; /* data moves size + 1 more */
i += size + 1; /* i moves only size + 1 */
}
```
A TLV option occupies size + 2 bytes. `data` is advanced by size + 2 in total, `i` by size + 1, so
the offset falls one byte behind the real read position for every option the walk skips. After
enough skipped options the check `i < length - 1` still holds while `data` is already past the end
of the message, and the subsequent read of the type and length bytes comes from whatever follows.
A single OFFER carrying a long run of skippable options is enough:
```
ERROR: AddressSanitizer: heap-buffer-overflow
READ of size 1 at 0x61b000000794 thread T5
#0 _nx_dhcp_search_buffer addons/dhcp/nxd_dhcp_client.c:7541
#1 _nx_dhcp_get_option_value addons/dhcp/nxd_dhcp_client.c:7082
0x61b000000794 is located 164 bytes to the right of 1648-byte region
```
A well formed OFFER through the same path is handled normally, the client records the offer and
moves to REQUESTING, so the difference is the option layout rather than the harness.
The read runs in the DHCP client thread while the client is still unconfigured, so it happens on
every boot in reach of a hostile DHCP responder. The values read are used to configure the
interface, which is how the disclosed bytes become observable.
Advance `i` by size + 2, or derive the bound from `data` rather than keeping a second counter. |
| An unprivileged, memory-protected ThreadX module can have the kernel read and write memory at addresses of its choosing, in privileged mode, and can use that to clear the MPU enable bit and remove its own isolation boundary.
The Module Manager decided whether a privileged service could dereference an object address a module named by asking only whether that address fell outside the module. The manager's object pool is outside every module, so the test was satisfied by an address shifted into the interior of one of the module's own privileged allocations, which denotes no object at all. The bytes such an address presents as a control block are bytes the module put there through ordinary create and set services, so the control block ID at the front of them could be made to read as any type the module chose, and the `_txe_` layer's ID test then agreed. The reported chain uses that to reach a privileged `memset` across an attacker-chosen range. |
| An unauthenticated client can drain the RTSP server's packet pool with a couple of dozen requests
that carry a Session header the parser cannot convert.
The Session branch returns the raw NetX error code instead of an RTSP status code:
```c
/* addons/rtsp/nx_rtsp_server.c:2754 */
status = _nx_utility_string_to_uint(field_value_ptr, field_value_length, &session_id);
if (status)
{
return(status); /* NX_INVALID_PARAMETERS / NX_SIZE_ERROR / NX_OVERFLOW */
}
```
Every other branch of the same function maps its failure to an RTSP status first. The CSeq branch
eighteen lines earlier does exactly that (line 2736 returns NX_RTSP_STATUS_CODE_BAD_REQUEST). The
raw code then reaches `_nx_rtsp_server_error_response_send` (nx_rtsp_server.c:1234), which does not
recognise it, takes a path that returns without releasing the response packet it already allocated,
and the block never goes back to the pool.
Six requests with an empty Session header against a 22 packet pool:
```
valid requests: after request 6: pool available = 21, AFTER = 22 / 22
malformed requests: after request 6: pool available = 16, AFTER = 17 / 22
```
One block per request, not returned when the client disconnects. Twenty six requests take the pool
to zero and the server starts failing allocations, after which it serves nobody. If the pool is
shared with the rest of the application, as it is in the shipped sample, the rest of the stack
stops with it.
Convert the `_nx_utility_string_to_uint` failure in the Session branch into
NX_RTSP_STATUS_CODE_BAD_REQUEST the way the CSeq branch does, and release the response packet on
every exit path of `_nx_rtsp_server_error_response_send`. |
| Any host on the LAN can send two mDNS records and make the responder write past the end of its
transmit packet.
The string table stores each name in a slot rounded up to a multiple of four:
```c
/* addons/mdns/nxd_mdns.c:11436, 11443, 11447 */
memory_len = ((memory_len & 0xFFFFFFFC) + 8) & 0xFFFFFFFF;
...
len = *((USHORT*)(p - 2)); /* slot size, not string length */
if ((len == memory_len) && ... _nx_mdns_name_match(start, memory_ptr, memory_size) ...)
```
The lookup that decides whether an incoming name is already stored compares the rounded slot size,
so names of 12, 13, 14 and 15 characters share one bucket. A second name in the bucket is answered
with the pointer to the first, and the record then carries a string up to three bytes longer than
the length the caller accounted for. `_nx_mdns_packet_rr_add` (nxd_mdns.c:8911) sizes its only
bound check from that stale length, and `_nx_mdns_name_string_encode` writes the real string.
Two PTR records are enough, both ordinary mDNS responses to a `_http._tcp` query, with owner names
whose lengths fall in the same bucket:
```
==87491==ERROR: AddressSanitizer: heap-buffer-overflow
WRITE of size 1 at 0x611000000124 thread T5
#0 _nx_mdns_name_string_encode addons/mdns/nxd_mdns.c:13096
#1 _nx_mdns_packet_rr_add addons/mdns/nxd_mdns.c:8911
0x611000000124 is 0 bytes to the right of 228-byte region
```
The overflow is one to three bytes of attacker-influenced name data past `nx_packet_data_end`. In a
normal pool that lands in the next packet in the same pool rather than in a redzone, so the visible
effect is a corrupted neighbouring packet or a corrupted pool free list rather than a clean crash.
Compare the slot size against the stored string length before declaring a match, or keep the
string length in the slot header and return it to the caller so the encoder and the bound check
agree. |
| In Eclipse BaSyx Java Server SDK versions prior to 2.0.0-milestone-10, inadequate path normalization in the Submodel HTTP API allows an unauthenticated remote attacker to perform a path traversal attack. By supplying a maliciously crafted fileName parameter during a file upload operation, an attacker can bypass intended storage boundaries and write arbitrary files to any location on the host filesystem accessible by the Java process. This can lead to Remote Code Execution (RCE) and complete system compromise. |
| The open-vsx.org deployment returned Access-Control-Allow-Origin reflecting the requesting origin together with Access-Control-Allow-Credentials: true on the authenticated /user/ endpoints. A page on any origin could therefore issue credentialed requests to the service in a logged-in user's browser and read the responses.
This exposed /user (login name, avatar, homepage, tokens URL), /user/tokens, /user/namespaces, /user/extensions, /user/search/{name} and /user/namespace/{name}/members, and — because /user/csrf was readable the same way — allowed the CSRF protection on write endpoints to be defeated. Chaining the two, an attacker page could call /user/token/create and exfiltrate a personal access token carrying publish and delete rights over the victim's namespaces.
The headers were emitted by the CDN/edge layer, not by the application: the Open VSX software sets allowCredentials(true) in exactly one place, against a single exact origin derived from ovsx.webui.url, and defines no CORS mapping on /user/ beyond it. No configuration of the software produces origin reflection with credentials. |
| UrlUtil.getBaseUrl builds the absolute URLs in a response — download links, icons, asset and API URLs — from the X-Forwarded-Host, X-Forwarded-Proto and X-Forwarded-Prefix request headers, with no check on whether the sender was a trusted proxy, falling back to the client-supplied Host header.
Those responses are cached under keys that do not include the host (extension.json since 0.6.0, namespace.details.json since 0.9.0, sitemap since 0.14.5, latest.extension.version.vscode since 0.34.2). A single request carrying a forged header therefore places attacker-chosen URLs into an entry served to every other client for the lifetime of that entry — one hour by default, and cluster-wide where ovsx.redis.enabled is set.
The VSIX download URL, its signature URL and the public key URL are all derived from the same base URL, so extension signing does not limit the impact: an attacker who poisons an entry supplies the package, the signature over it, and the key used to verify it.
Exploitability depends on deployment topology. A server reachable directly by clients, or fronted by a proxy that relays the client's X-Forwarded-Host rather than overwriting it, is exploitable by an unauthenticated remote attacker. A proxy that overwrites the header is not.
An unauthenticated attacker can poison Open VSX's per-extension metadata cache with attacker-controlled download, signature, and public-key URLs by supplying a crafted X-Forwarded-Host header, causing downstream VS Code-compatible editors to fetch and install a malicious VSIX.
Workarounds (unpatched versions)
1. Configure the reverse proxy to set rather than relay X-Forwarded-Host, X-Forwarded-Proto and X-Forwarded-Prefix — note that nginx's $host is the client's Host header and is not a safe value.
2. Ensure the server is not reachable except through that proxy.
3. Flush the caches afterwards; poisoned entries survive the configuration change. |
| In Eclipse iceoryx2 versions greater than v0.8.0, the StaticString exposes its contents as mutable bytes through safe APIs, while String::as_str() converts those bytes into a Rust string slice without validating UTF-8. An application can therefore create an invalid &str and trigger undefined behavior using entirely safe Rust. |
| In Eclipse Embedded CDT versions 6.0 to 6.7 if the CMSIS-Pack archive extracts a compromised CMSIS pack the archive extraction can extract files to locations outside of the pack, allowing writing of arbitrary files to other locations on disk. |
| In Eclipse Ankaios versions 0.1.0 through 1.0.2, the agent creates workload files and Control Interface named pipes (FIFOs) under a predictable path derived from the agent name and a hash of the workload's runtime configuration. If a directory or FIFO already exists at that path when the agent (re)starts, the agent reuses it based only on an existence and/or file-type check, without validating its owner or permissions. A local, unprivileged user with write access to the same base directory (by default under `$TMPDIR/ankaios`, e.g. shared `/tmp`) can pre-create this path hierarchy, including the two Control Interface FIFOs, before the agent starts. The agent then treats the attacker-owned FIFOs as the legitimate Control Interface for the targeted workload. The attacker can complete the Control Interface handshake and issue requests using that workload's configured `controlInterfaceAccess` permissions, allowing impersonation of the workload and, depending on its configured permissions, unauthorized reading and/or modification of the cluster's desired state. |
| In Eclipse Ankaios versions 0.6.0 to before 1.0.4, `LogRule::matches` in the agent control-interface authorizer stops at the first wildcard pattern in a single rule instead of evaluating later entries, which can cause deny `LogRule` entries to be skipped and allow unauthorized access to another workload's logs. |
| In the current development version of Eclipse aeriOS, for which no official release has yet been published, the Identity Manager (IdM) deployment included insecure default configurations and credentials for security-sensitive services.
The Helm chart exposed the Keycloak service and its PostgreSQL backing database through Kubernetes NodePort services by default, while the Docker Compose deployment similarly exposed PostgreSQL on all network interfaces. The deployment included fixed default credentials for the Keycloak administrator and PostgreSQL database user, and the previous Helm chart configuration did not provide adequate secret management for these credentials. In addition, predefined application users with known credentials were provided for development and testing without sufficiently warning operators against their use in production environments.
An attacker able to reach the exposed services could use the published default credentials to obtain administrative access to the Identity Manager or direct access to its database. This could allow unauthorized access to or modification of identity-management data, including users, roles, client credentials, sessions, and cryptographic material, and could enable the creation of privileged identities or tokens accepted by other aeriOS components.
The issue has been addressed by generating a random Keycloak administrator password by default, managing Keycloak and PostgreSQL credentials through Kubernetes Secrets, and restricting PostgreSQL to an internal service in both the Helm chart and Docker Compose deployment. OpenLDAP is also restricted to an internal service. The predefined users intended for development and testing are retained, but the documentation now explicitly warns that their default credentials must not be used in production and that these users should be removed or their credentials changed after installation. |
| In Eclipse Ditto's Node.js JavaScript client, all released versions of @eclipse-ditto/ditto-javascript-client-node from 2.0.0 to 3.9.0 and of its predecessor package @eclipse-ditto/ditto-javascript-client-node_1.0 from 1.0.0 to 2.1.0, the WebSocket transport hard-codes rejectUnauthorized: false when creating the underlying ws WebSocket. Certificate chain and hostname validation are therefore disabled for every wss:// connection, and no builder option, constructor argument or environment variable lets an application turn validation back on. An attacker in a position to intercept the connection can present an arbitrary certificate, complete the TLS handshake, read the credentials that the configured authentication provider sends in the Authorization header of the WebSocket upgrade request, and read, alter or inject Ditto Protocol messages for the lifetime of the connection. The Java client, the browser/DOM JavaScript client and the HTTP transport of the Node.js client are not affected. |
| A client may issue HTTP/2 requests to a Jetty server that result in blocking writes that are never unblocked, eventually causing all threads to be blocked and the whole server to become unresponsive.
This is caused by a race condition in the server when handling RST_STREAM frames and GOAWAY frames sent by the client.
The race condition "resets" the HTTP2Flusher.terminated, previously set to a non-null value, to the null value, allowing entries to be enqueued in the flusher that however will never be processed. These unprocessed entries are the ones that would unblock the write-blocked threads. |
| In Eclipse Ankaios versions v0.5.1 through v1.0.1, the agent-side Control Interface authorizer incorrectly evaluates multi-segment allow rules whose first path segment is a wildcard. An authenticated workload with access restricted by such a rule can submit a CompleteStateRequest or UpdateStateRequest with an empty field mask. The request may then be incorrectly authorized as matching the scoped rule, allowing the workload to read the complete cluster state or replace state outside its authorized subtree. This may result in unauthorized disclosure or modification of other workloads and cluster configuration. Only a rule consisting solely of * is intended to authorize an empty mask.
Mitigation: Until an update containing the fix is installed, avoid multi-segment Control Interface allow-rule filter masks that begin with a wildcard, such as *.workloads.some_workload. Replace them with explicit paths such as desiredState.workloads.some_workload, where applicable. A filter mask consisting solely of * has different, intentionally unrestricted semantics and should only be used when full-state access is intended. |
| In Eclipse Ankaios versions 0.1.0 through 1.0.1, the agent does not limit the length declared by a workload in a length-delimited protobuf message received through the Control Interface FIFO. A workload granted Control Interface access can specify an excessive message length, causing an unbounded memory allocation that may abort the Ankaios agent process. This results in loss of orchestration services for workloads managed by the affected agent. |
| A client may send a WebSocket frame with an unknown opcode and a very large declared payload length, causing Jetty to attempt a large memory allocation and potentially exhaust the JVM heap.
This occurs when auto-fragmentation is enabled, as unknown opcodes bypass the normal maximum frame size handling and payload allocation occurs before the opcode is validated. |
