CVE-2024-1683

Service execution via modifiable application files

Published Feb 23, 2024 · Updated Aug 1, 2024

DLL injection in Tenable Identity Exposure Secure Relay 3.42.17 through 3.59.3 allows local users to run new Secure Relay services. Tenable states that low-privileged users can modify application files and override configuration, but it does not identify the affected file, DLL-loading path, or unsafe operation. Exploitation requires authenticated local access and can alter relay configuration and execute code through attacker-defined services.
