Summary
pgAdmin <= 8.3 is affected by a path-traversal vulnerability while deserializing users’ sessions in the session handling code. If the server is running on Windows, an unauthenticated attacker can load and deserialize remote pickle objects and gain code execution. If the server is running on POSIX/Linux, an authenticated attacker can upload pickle objects, deserialize them, and gain code execution.
Sources
1Python PoC exploiting CVE-2024-2044 in pgAdmin 4 (<=8.3) via authenticated path traversal and unsafe pickle deserialization to achieve remote code execution and reverse shell.
