CyberRota Analysis

AI-Generated

The skill-scan component of Tencent AI-Infra-Guard is vulnerable due to its exclusion of compiled Python bytecode files from security analysis, specifically ignoring __pycache__ directories and .pyc/.pyo/.pyd extensions. This oversight allows attackers to package malicious bytecode with seemingly benign Python source files, leading to potential code execution upon skill installation. Organizations utilizing Tencent AI-Infra-Guard should prioritize addressing this vulnerability to mitigate risks associated with malicious skill deployment.

Original NVD Description

Tencent AI-Infra-Guard's skill-scan component excludes compiled Python bytecode files from analysis by hardcoding __pycache__ directories and .pyc/.pyo/.pyd extensions into skip lists across multiple scanning surfaces. Attackers can distribute skills with benign Python source files alongside malicious compiled bytecode that executes on import while the scanner reports a safe verdict, enabling code execution when operators install the skill.
