Eclipse Foundation vulnerabilities

Attacker model / Preconditions: a loaded `TXM_MODULE_USER_MODE | TXM_MODULE_MEMORY_PROTECTION` module issuing kernel dispatch calls, on a build with `TX_ENABLE_EVENT_TRACE`. A user-mode, memory-protected module can register an arbitrary function pointer as the global trace-full callback. The kernel calls it directly — no validation, no trampoline — from privileged kernel code when the trace buffer wraps. An invalid pointer faults the kernel (DoS). A pointer into the module's own code was observed running with kernel privilege (`CONTROL.nPRIV = 0`), confirmed at runtime with a register capture inside that code.

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 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 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.
