Title:	Debian: Security Advisory (DLA-3401-1)
Summary:	The remote host is missing an update for the Debian 'apache2' package(s) announced via the DLA-3401-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'apache2' package(s) announced via the DLA-3401-1 advisory. Vulnerability Insight: Several vulnerabilities have been discovered in apache2, a webserver that may be used as front-end proxy for other applications. These vulnerabilities may lead to HTTP request smuggling, and thus to front-end security controls being bypassed. Unfortunately, fixing these security vulnerabilities may require changes to configuration files. Some out-of-specification RewriteRule directives that were previously silently accepted, are now rejected with error AH10409. For instance, some RewriteRules that included a back-reference and the flags '[L,NC]' will need to be written with extra escaping flags such as '[B= ?,BNP,QSA]'. CVE-2023-25690 Some mod_proxy configurations allow an HTTP request Smuggling attack. Configurations are affected when mod_proxy is enabled along with some form of RewriteRule or ProxyPassMatch in which a non-specific pattern matches some portion of the user-supplied request-target (URL) data and is then re-inserted into the proxied request-target using variable substitution. CVE-2023-27522 HTTP Response Smuggling in mod_proxy_uwsgi For Debian 10 buster, these problems have been fixed in version 2.4.38-3+deb10u10. We recommend that you upgrade your apache2 packages.
