Description
Summary of Vulnerability
Certain versions of Jira Service Management Server & Data Center were affected by CVE-2019-13990. The affected versions contained vulnerable versions of Terracotta Quartz Scheduler which allowed authenticated attackers to initiate an XML External Entity injection attack using job descriptions.
Atlassian has committed to issuing critical advisories based on the NVD vulnerability score, in this case the CVSS for this third party CVE is critical (9.8), but this score doesn’t always account for the context in which a vulnerable component is used in our software. Unauthenticated attackers without local access to the system are unable to exploit this vulnerability. As such, our internal assessment of this vulnerability is scored as high severity.
This critical severity XXE (XML External Entity Injection) vulnerability known as CVE-2019-13990 affects versions including and after 4.20.0 of Jira Service Management Data Center and Server. Versions outside of the support window (i.e. versions that have reached End of Life) may also be affected, so Atlassian recommends you upgrade to a fixed LTS version or later.
