Signalk Server
Monthly
Signal K Server prior to version 2.24.0 permits low-privileged authenticated users to bypass prototype boundary filtering via a malformed `from` field, enabling arbitrary read access to internal functions and properties in the global prototype object. This confidentiality breach violates data isolation within the Signal K application and allows attackers to extract sensitive internal state they should not access. The vulnerability requires prior authentication and has been patched in version 2.24.0.
SignalK Server versions prior to 2.24.0 allow unauthenticated attackers to hijack OAuth2 sessions and steal authorization codes by spoofing the HTTP Host header in OIDC login and logout handlers. The vulnerability exploits the default-unset redirectUri configuration, causing the OIDC provider to send authorization codes to an attacker-controlled domain. EPSS score of 6.1 reflects moderate real-world risk despite the requirement for user interaction (UI:R) to initiate login.
SignalK Server prior to version 2.24.0-beta.1 allows unauthenticated remote attackers to modify navigation data source priorities through an unprotected PUT endpoint (/signalk/v1/api/sourcePriorities), enabling manipulation of which GPS, AIS, and sensor data sources are trusted by the maritime navigation system. The malicious configuration changes are immediately applied and persisted to disk, surviving server restarts and potentially causing the vessel to rely on attacker-controlled or spoofed navigation data. No public exploit code or active exploitation has been confirmed at this time.
Unauthenticated privilege escalation in SignalK Server (versions prior to 2.24.0-beta.4) allows remote attackers to inject administrator roles via the /enableSecurity endpoint, granting full administrative control without credentials. Attackers can modify vessel routing data, alter server configurations, and access all restricted endpoints. No public exploit identified at time of analysis, but the critical CVSS 9.4 score reflects the trivial exploit complexity (AV:N/AC:L/PR:N) and high confidentiality/integrity impact to marine vessel control systems.
