Atlassian Crowd 7.1.x < 7.1.7 Path Traversal

critical Web App Scanning Plugin ID 115651

Synopsis

Atlassian Crowd 7.1.x < 7.1.7 Path Traversal

Description

According to its self-reported version number, the Atlassian Crowd application running on the remote host is prior to 6.3.7, 6.4.x prior to 7.0.3, 7.1.x prior to 7.1.7 or 7.2.x prior to 7.2.4. It is, therefore, affected by a path traversal vulnerability which allows an unauthenticated attacker to access specific files within the web application root directory.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Atlassian Crowd version 7.1.7 or later.
