Note: The issue below was fixed in Apache Tomcat 10.1.0-M9 but the release vote for the 10.1.0-M9 release candidate did not pass. Therefore, although users must download 10.1.0-M10 to obtain a version that includes a fix for these issues, version 10.1.0-M9 is not included in the list of affected versions.

Low: Local Privilege Escalation CVE-2022-23181

The fix for bug CVE-2020-9484 introduced a time of check, time of use vulnerability that allowed a local attacker to perform actions with the privileges of the user that the Tomcat process is using. This issue is only exploitable when Tomcat is configured to persist sessions using the FileStore.

This was fixed with commit 70da1aaa.

This issue was reported to the Apache Tomcat Security team by Trung Pham of Viettel Cyber Security on 10 December 2021. The issue was made public on 26 January 2022.

Affects: 10.1.0-M1 to 10.1.0-M8
