medium Nessus Plugin ID 139798

Language:

Synopsis

The remote web server hosts a web application that is affected by a denial of service vulnerability.

Description

According to its self-reported version number, the instance of Atlassian Jira hosted on the remote web server is version 7.6.x prior to 8.5.4 or 8.6.x prior to 8.7.1. It is, therefore, affected by a denial of service (DoS) vulnerability in the User Management - User Profile component. An authenticated, remote attacker can exploit this issue via the avatar upload feature, by uploading a specially crafted PNG file to cause a denial of service condition.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Atlassian Jira version 8.5.4, 8.7.1, 8.8.0 or later.
