Duplicate Advisory: Picklescan is missing detection when calling built-in Python cProfile.runctx
### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-9w88-8rmg-7g2p. This link is maintained to preserve external references. ### Original Description picklescan before 0.0.30 fails to detect cProfile.runctx function calls in pickle file reduce methods, allowing attackers to execute arbitrary code. Malicious pickle files bypass picklescan detection and execute remote code when loaded via pickle.load().
AI Analysis
Technical Summary
Picklescan before version 0.0.30 fails to detect the use of the cProfile.runctx function call in pickle file reduce methods. This detection failure enables attackers to craft malicious pickle files that can bypass picklescan's detection mechanisms and execute arbitrary remote code upon deserialization with pickle.load(). The vulnerability is identified as CWE-502 (Deserialization of Untrusted Data) and has a CVSS 3.1 score of 8.1, indicating high severity. A fix has been made available in versions 0.0.30 and later.
Potential Impact
Attackers can exploit this vulnerability by crafting malicious pickle files that include calls to cProfile.runctx in their reduce methods. When these pickle files are loaded with pickle.load(), arbitrary code execution can occur, potentially compromising the affected system. The vulnerability affects confidentiality and integrity but does not impact availability.
Mitigation Recommendations
Users should upgrade picklescan to version 0.0.30 or later where this detection issue has been fixed. Since a patch is available, applying the official fix is the recommended remediation. No additional mitigation steps are indicated by the vendor advisory.
