Descriptions

Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability during JSP compilation in Apache Tomcat permits an RCE on case insensitive file systems when the default servlet is enabled for write (non-default configuration). This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.1, from 10.1.0-M1 through 10.1.33, from 9.0.0.M1 through 9.0.97. Users are recommended to upgrade to version 11.0.2, 10.1.34 or 9.0.08, which fixes the issue.

A flaw was found in Tomcat. A Time-of-check Time-of-use (TOCTOU) race condition occurs during JSP compilation on case-insensitive file systems when the default servlet is enabled for writing. This vulnerability allows an uploaded file to be treated as a JSP and executed, resulting in remote code execution.

Red Hat JBoss Web Server 5.8.2 zip release is now available for Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, and Windows Server.
