CVE-2024-34715: 
Python vulnerability analysis and mitigation

Fides, an open-source privacy engineering platform, was found to have a vulnerability in its webserver that affects database password handling. The vulnerability (CVE-2024-34715) was disclosed on May 29, 2024, and involves the exposure of partial database passwords in webserver error logs when the password contains special characters such as '@' and '$'. This issue affects versions of Fides prior to 2.37.0 and is caused by improper escaping of the SQLAlchemy password string (GitHub Advisory).

The vulnerability stems from insufficient validation of database connection passwords in the Fides webserver. When connecting to a hosted PostgreSQL database for persistent storage, if the password contains special characters like '@' or '$', the webserver startup process fails and exposes the portion of the password following the special character in the error logs. This is specifically caused by improper escaping of the SQLAlchemy password string. The issue has been assigned a CVSS v3.1 base score of 2.3 (Low) with a vector string of CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:N (GitHub Advisory).

The vulnerability results in partial exposure of hosted database passwords in webserver logs. When a password containing special characters is used, the portion of the password following the special character becomes visible in error logs, potentially exposing sensitive authentication information (GitHub Advisory).

The vulnerability requires local access and high privileges to exploit. The attack complexity is low and does not require user interaction. The scope is unchanged, meaning the impact is limited to the scope of the affected component (GitHub Advisory).

The vulnerability has been patched in Fides version 2.37.0. Users are advised to upgrade to this version or later to secure their systems against this threat. There are no known workarounds for this vulnerability (GitHub Advisory).
