Overview

AI description

Automated description summarized from trusted sources.

CVE-2025-55752 is a relative path traversal vulnerability affecting Apache Tomcat. The vulnerability stems from a regression introduced while fixing a previous bug, where rewritten URLs were normalized before being decoded. This allows attackers to manipulate request URIs through rewritten query parameters, potentially bypassing security constraints and accessing sensitive directories like /WEB-INF/ and /META-INF/. If PUT requests are enabled, which is not a typical configuration, attackers could exploit this flaw to upload malicious files, potentially leading to remote code execution (RCE). The vulnerability affects Apache Tomcat versions 11.0.0-M1 to 11.0.10, 10.1.0-M1 to 10.1.44, and 9.0.0.M11 to 9.0.108, as well as older, end-of-life versions.

Description: Relative Path Traversal vulnerability in Apache Tomcat. The fix for bug 60013 introduced a regression where the rewritten URL was normalized before it was decoded. This introduced the possibility that, for rewrite rules that rewrite query parameters to the URL, an attacker could manipulate the request URI to bypass security constraints including the protection for /WEB-INF/ and /META-INF/. If PUT requests were also enabled then malicious files could be uploaded leading to remote code execution. PUT requests are normally limited to trusted users and it is considered unlikely that PUT requests would be enabled in conjunction with a rewrite that manipulated the URI. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.10, from 10.1.0-M1 through 10.1.44, from 9.0.0.M11 through 9.0.108. The following versions were EOL at the time the CVE was created but are known to be affected: 8.5.6 though 8.5.100. Other, older, EOL versions may also be affected. Users are recommended to upgrade to version 11.0.11 or later, 10.1.45 or later or 9.0.109 or later, which fix the issue.
