CVE-2022-1257 is an insecure storage of sensitive information vulnerability affecting MA for Linux, macOS, and Windows prior to version 5.7.6. Sensitive information was stored in the ma.db database file without adequate protection, allowing a local user to access that data directly from local storage. The vendor indicates that the issue was addressed by moving the sensitive information into encrypted database files in version 5.7.6.

This repository contains a PowerShell proof-of-concept exploit for CVE-2022-1257, a vulnerability in McAfee (Trellix) Agent prior to version 5.7.6. The exploit targets the agent's database file (ma.db), which insecurely stores sensitive credentials. The script (CVE-2022-1257.ps1) copies the ma.db file to a temporary location, queries it for usernames and encrypted passwords, and then decrypts the passwords using a static XOR mask and 3DES with a hardcoded key. The output is a CSV of usernames and their decrypted passwords. The exploit requires local access to the target system, PowerShell 5.1+, and winsqlite3.dll (native to Windows 11). The repository also includes a README.md with detailed usage instructions, prerequisites, and references. No network endpoints are involved; the attack is purely local and file-based.
