According to its self-reported version number, the instance of Atlassian Jira hosted on the remote web server is affected by a missing authentication flaw in its Ehcache RMI component. An unauthenticated, remote attacker could exploit this to bypass authentication and execute arbitrary code on an affected system.
Note that Nessus has not tested for this issue but has instead relied only on the applicationβs self-reported version number.
