Related CVEs CVE-2024-38473


A vulnerability was found in apache2, a popular web server.

An encoding problem in mod_proxy allowed request URLs with incorrect encoding to be sent to backend services, potentially bypassing authentication via crafted requests.

This affects configurations where mechanisms other than ProxyPass/ProxyPassMatch or RewriteRule with the ‘P’ flag are used to configure a request to be proxied, such as SetHandler or inadvertent proxying via CVE-2024-39573.

Note that these alternate mechanisms may be used within .htaccess.



For Debian 10 buster, these problems have been fixed in version 2.4.59-1~deb10u4.

We recommend that you upgrade your apache2 packages.
