Atlassian JIRA < 6.4.10 / 7.0.0-OD-02 MitM Plaintext Disclosure (Bar Mitzvah)

Low Nessus Plugin ID 87218

Synopsis

The remote web server hosts a web application that is potentially affected by a security feature bypass vulnerability.

Description

According to its self-reported version number, the instance of Atlassian JIRA hosted on the remote web server is prior to 6.4.10 or 7.0.0-OD-02. It is, therefore, potentially affected by a security feature bypass vulnerability, known as Bar Mitzvah, due to improper combination of state data with key data by the RC4 cipher algorithm during the initialization phase. A man-in-the-middle attacker can exploit this, via a brute-force attack using LSB values, to decrypt the traffic.

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 6.4.10 / 7.0.0-OD-02 or later.
