Apache · Apache Tomcat · CVE-2024-24549
**Name of the Vulnerable Software and Affected Versions**
Apache Tomcat versions prior to 11.0.0-M1, 10.1.0-M1, 9.0.0-M1, 8.5.0 through 8.5.98.
**Description**
The vulnerability in Apache Tomcat is due to improper input validation for HTTP/2 requests, leading to potential DoS conditions. If the request exceeded any of the configured limits for headers, the associated HTTP/2 stream was not reset until after all of the headers had been processed. This issue affects Apache Tomcat versions from 11.0.0-M1 through 11.0.0-M16, from 10.1.0-M1 through 10.1.18, from 9.0.0-M1 through 9.0.85, from 8.5.0 through 8.5.98. Users are recommended to upgrade to version 11.0.0-M17, 10.1.19, 9.0.86 or 8.5.99 which fix the issue.
**Recommendations**
To resolve the issue, users are recommended to upgrade to the latest version of Apache Tomcat, specifically to versions 11.0.0-M17, 10.1.19, 9.0.86, or 8.5.99. Upgrading to these versions will fix the vulnerability and prevent potential DoS conditions. Additionally, users can temporarily disable the `vulnerableFunction()` function until a patch is available, or restrict access to the vulnerable module to minimize the risk of exploitation. However, these are temporary measures and should not be used as a permanent solution. Users should follow the release notes for the latest version of Confluence Data Center and Server and download the latest version from the download center.
