descriptionAccording to its self-reported version number, the version of Atlassian JIRA hosted on the remote web server is prior to 5.0.1. It is, therefore, potentially affected by an XML parsing flaw due to improper restrictions on the capabilities of third-party parsers. A remote, authenticated attacker can exploit this to perform a denial of service attack against JIRA. The Tempo and Gliffy plugins for JIRA are also affected by this vulnerability; however, Nessus did not confirm that these plugins are installed. If you are using these plugins with any version of JIRA, you should upgrade or disable them. Note that Nessus has not tested for these issues but has instead relied only on the application
