Affected versions of Atlassian Jira Server and Data Center allow remote attackers to impact the application's availability via a Denial of Service (DoS) vulnerability in the GIF Image Reader component. The affected versions are before version 8.13.14, and from version 8.14.0 before 8.19.0.

The version of Atlassian Jira installed on the remote host is prior to < 8.13.14 / 8.14.x < 8.19.0. It is, therefore, affected by a vulnerability as referenced in the JRASERVER-72738 advisory.

  - Denial of Service when reading particularly-crafted GIF files - CVE-2021-39116 (CVE-2021-39116)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

According to its self-reported version number, the instance of Atlassian Jira hosted on the remote web server is prior to 8.19.0. It is, therefore, affected by multiple vulnerabilities:

- A broken access control vulnerability in the issue notification feature allowing users who have watched an issue to continue receiving updates on the issue even after their Jira account is revoked. (CVE-2021-39119)

- A denial of service (DoS) vulnerability in the GIF Image Reader component allowing remote attackers to impact the application's availability. (CVE-2021-39116) - A vulnerability that permits remote attackers to discover the usernames and full names of users via an enumeration vulnerability in the /rest/api/1.0/render endpoint.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.
