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

medium Nessus Plugin ID 87218
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 web server hosts a web application that is potentially affected by a security feature bypass vulnerability.


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.


Upgrade to Atlassian JIRA version 6.4.10 / 7.0.0-OD-02 or later.
