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.
