AI Analysis
Technical Summary
WsgiDAV, a WebDAV server based on WSGI, has a CWE-22 path traversal vulnerability in versions 4.3.3 and prior. An attacker can craft a WebDAV request path containing an encoded parent-directory segment to bypass the filesystem share root restriction, potentially accessing unauthorized files outside the intended directory. The vulnerability is fixed in version 4.3.4.
Potential Impact
Successful exploitation could lead to unauthorized disclosure and modification of files outside the intended filesystem share root, impacting confidentiality and integrity. The CVSS v3.1 score is 7.1 (high), reflecting network attack vector, high impact on confidentiality and integrity, low privileges required, and high attack complexity.
Mitigation Recommendations
Upgrade to WsgiDAV version 4.3.4 or later, where this path traversal vulnerability is fixed. No other official remediation or temporary fixes are documented. Patch status is not explicitly confirmed in vendor advisory, but the fix is stated to be in version 4.3.4.
