DLL Search Order Hijacking in LUCID Vision Labs Arena SDK

Executive Summary

DLL Search Order Hijacking in LUCID Vision Labs Arena SDK 1.0.80.49 on Windows allows a local attacker to execute arbitrary code with the privileges of the application by placing a malicious DLL in a user-controlled directory listed in the PATH environment variable, which the SDK traverses when a required dependency is not found locally.

Detection Guidance

To detect DLL Search Order Hijacking in LUCID Vision Labs Arena SDK, check for missing dependencies like log4cpp.dll in the SDK installation directory. Inspect the PATH environment variable for user-writable directories that could host malicious DLLs. Use process monitoring tools like Process Monitor to observe DLL loading behavior.
