Atlassian Bitbucket Server 4.x < 4.8.2 Directory Traversal

high Nessus Network Monitor Plugin ID 9941
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Bitbucket server is affected by an Dierctory Traversal attack vector.


Versions of Bitbucket 4.x prior to 4.8.2 contain a flaw in boundaries in content-type headers when handling file upload requests. This may allow a remote attacker to cause a process linked against the library to become unresponsive.


Upgrade to Bitbucket version 4.8.2 or later.
