A directory-traversal flaw tracked as CVE-2007-0450 affects Apache HTTP Server deployments that proxy requests to vulnerable Apache Tomcat instances through mod_proxy, mod_rewrite, or mod_jk. The inconsistency arises because Tomcat treats forward slashes, backslashes, and URL-encoded backslashes as path separators differently from Apache HTTP Server.
A remote attacker can send crafted .. path sequences using these alternate separators to bypass path restrictions and read arbitrary files accessible to the Tomcat process. Affected versions include Tomcat 5.x before 5.5.22 and Tomcat 6.x before 6.0.10; organizations using the affected proxy configurations should upgrade Tomcat and review exposed applications for traversal attempts.

The CVE-2007-0450 record was updated.
CVE-2007-0450 was published for a directory-traversal flaw affecting Apache HTTP Server deployments that proxy to vulnerable Apache Tomcat versions. Remote attackers could use crafted dot-dot paths with slash, backslash, or URL-encoded backslash separators to read arbitrary files when mod_proxy, mod_rewrite, or mod_jk is used.

Apache Tomcat JK Web Server Connector (`mod_jk`) versions 1.2.x before 1.2.23 contain a directory-traversal and authorization-bypass flaw tracked as **CVE-2007-1860**. The issue arises because Apache HTTP Server decodes a request URL before passing it to Tomcat, allowing the two components to interpret the path differently. A remote attacker could craft requests using a `JkMount` prefix, including double-encoded `..` path sequences, to bypass access controls and reach protected pages. Organizations using affected `mod_jk` deployments should upgrade to version 1.2.23 or later and review exposed mounted paths and authorization rules for potential unauthorized access.

Apache Tomcat contained a limited directory-traversal flaw, tracked as **CVE-2015-5174**, in `RequestUtil.java`. Improper validation in the `ServletContext` `getResource()`, `getResourceAsStream()`, and `getResourcePaths()` methods allowed a `/..` path component during web-application resource lookups. A remote authenticated user controlling a malicious web application could exploit the issue under a Java SecurityManager to enumerate the application deployment parent directory, typically `$CATALINA_BASE/webapps`, bypassing intended restrictions. Apache corrected the flaw in Tomcat 6.0.45, 7.0.65, and 8.0.27; Tomcat 9 is not affected.

Apache Tomcat disclosed **CVE-2015-5345**, a low-severity information-disclosure flaw that lets unauthenticated users determine whether protected directories or web-application roots exist. Tomcat processed redirects for directory URLs missing a trailing slash before applying security constraints, exposing the presence of resources that should not be discoverable. Apache corrected the request-processing order by moving redirect handling into `DefaultServlet`, ensuring security constraints and enforcement filters are evaluated before redirects occur. Organizations should upgrade to Tomcat 6.0.45, 7.0.67, 8.0.30, 9.0.0.M3, or later.
