CVE-2026-55488: CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in motioneye-project motioneye
motionEye (mEye) is an online interface for a piece of software called "motion," which is a video surveillance program with motion detection. Versions prior to 0.44.0 contain an absolute path traversal vulnerability in multiple media file handlers that allows an attacker to read arbitrary files from the filesystem. The affected handlers accept a user-controlled filename parameter and construct filesystem paths using `os.path.join()`. When an absolute path is supplied, Python discards the configured media directory and returns the attacker-supplied path directly. The application then bypasses Tornado's built-in path validation by overriding the relevant safety checks. As a result, an attacker can access files outside of the configured camera media directory, subject to the permissions of the motionEye process. Version 0.44.0 fixes the issue.
AI Analysis
Technical Summary
motionEye is a web interface for the motion video surveillance software. Versions before 0.44.0 have an absolute path traversal vulnerability (CWE-22) in several media file handlers. These handlers accept a user-controlled filename parameter and use Python's os.path.join() to build filesystem paths. However, when an absolute path is provided, Python discards the configured media directory, and the application overrides Tornado's path validation, allowing attackers to access files outside the intended directory. This can lead to unauthorized file disclosure limited by the permissions of the motionEye process. The issue is resolved in version 0.44.0.
Potential Impact
An attacker can read arbitrary files on the host filesystem accessible by the motionEye process by exploiting the path traversal vulnerability. This can lead to unauthorized disclosure of sensitive information stored outside the intended media directories. The vulnerability does not require authentication or user interaction and has a high severity score of 7.7.
Mitigation Recommendations
Upgrade motionEye to version 0.44.0 or later, where this path traversal vulnerability is fixed. No other mitigations are specified. Patch status is confirmed by the vendor stating the fix in version 0.44.0.
