This High severity Third-Party Dependency vulnerability was introduced in versions 8.20.0, 9.4.0, 9.8.0, 9.9.0, 9.10.0, and 9.11.0 of Jira Software Data Center and Server.
This Third-Party Dependency vulnerability, with a CVSS Score of 7.5 and a CVSS Vector of CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H allows an unauthenticated attacker to expose assets in your environment susceptible to exploitation which has no impact to confidentiality, no impact to integrity, high impact to availability, and requires no user interaction.
Atlassian recommends that Jira Software Data Center and Server customers upgrade to latest version, if you are unable to do so, upgrade your instance to one of the specified supported fixed versions:
- Jira Software Data Center and Server 9.11: Upgrade to a release greater than or equal to 9.11.3
See the release notes. You can download the latest version of Jira Software Data Center and Server from the download center.
The National Vulnerability Database provides the following description for this vulnerability: Incomplete Cleanup vulnerability in Apache Tomcat.
The internal fork of Commons FileUpload packaged with Apache Tomcat 9.0.70 through 9.0.80 and 8.5.85 through 8.5.93 included an unreleased,
in progress refactoring that exposed a potential denial of service on
Windows if a web application opened a stream for an uploaded file but
failed to close the stream. The file would never be deleted from disk
creating the possibility of an eventual denial of service due to the
disk being full.
Users are recommended to upgrade to version 9.0.81 onwards or 8.5.94 onwards, which fixes the issue.
Dear Atlassian team,
Please could you clarify the sentence: "This High severity Third-Party Dependency vulnerability was introduced in versions 8.20.0,.."
For me it is not clear if the vulnerability was in introduced in version 8.20.0 and remain in all later 8.20.x versions
or
if the vulnerability was only affects to version 8.20.0.
Is the only fix available other than 9.11.3? Is not any planned fixing for 8.20.X?
As a suggestion try to avoid the words " vulnerability was introduced" and use explicitly " vulnerability affected to". This will avoid misunderstandings.
Looking forward to your feedback,
Thanks in advance,
Cheers,
Roberto Correa
