The avatar upload feature in affected versions of Atlassian Jira Server and Data Center allows remote attackers to achieve Denial of Service via a crafted PNG file. The affected versions are before version 8.5.4, from version 8.6.0 before 8.6.2, and from version 8.7.0 before 8.7.1.

According to its self-reported version number, the instance of Atlassian Jira hosted on the remote web server is version 7.0.6 prior to 8.5.4 or 8.6.x prior to 8.7.1. It is, therefore, affected by multiple vulnerabilities:

- A flaw which permits remote attackers to achieve Denial of Service via a crafted PNG file (CVE-2019-20897).

- A flaw which allows remote attackers to inject arbitrary HTML or JavaScript via a cross site scripting (XSS) vulnerability.

Note that the scanner has not tested for these issues 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 version 7.6.x prior to 8.5.4 or 8.6.x prior to 8.7.1. It is, therefore, affected by a denial of service (DoS) vulnerability in the User Management - User Profile component. An authenticated, remote attacker can exploit this issue via the avatar upload feature, by uploading a specially crafted PNG file to cause a denial of service condition.

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