Dear LinuxPatch users, in our ongoing effort to keep your systems secure and up-to-date, we need to discuss an important security issue that has been identified in Apache Tomcat. Specifically, we're looking at CVE-2022-23181, a vulnerability with a high severity rating that demands immediate attention.
Apache Tomcat is a widely-used open-source Java servlet container developed by the Apache Software Foundation. It essentially powers numerous large-scale, enterprise-level web applications by providing a "pure Java" HTTP web server environment for Java code to run. Understanding the role of Tomcat is crucial, as it touches on multiple aspects of web infrastructure relevant to numerous organizations globally.
This vulnerability, identified as CVE-2022-23181, stems from a significant flaw that was ironically introduced while fixing a previous bug (CVE-2020-9484). This flaw is a classic example of a time of check to time of use (TOCTOU) insecurity, which arises due to inconsistent states between checking a condition and using the results of this check.
The Issue at Hand:
CVE-2022-23181 affects multiple versions of Tomcat, ranging from Tomcat 8.5.55 to 8.5.73, 9.0.35 to 9.0.56, and 10.0.0-M5 to 10.0.14, including the initial milestones of the 10.1.x series up to 10.1.0-M8. The vulnerability specifically impacts systems where Tomcat is configured to persist sessions using the FileStore. This is not a common configuration, but in cases where it is used, the risk is significant.
The vulnerability allows a local attacker—who must have access to the host machine—to perform unauthorized actions with the same privileges as the user running the Tomcat process. This could potentially lead to unauthorized data manipulation or exposure.
Impact:
The severity of this issue is not to be underestimated. With a CVSS (Common Vulnerability Scoring System) score of 7, it highlights a considerable risk that requires immediate patching. The integrity and confidentiality of your applications and data could be at risk if left unpatched.
