Debian LTS Advisory DLA-3401-1 [email protected]
https://www.debian.org/lts/security/ Bastien Roucariès
April 24, 2023 https://wiki.debian.org/LTS
Package : apache2
Version : 2.4.38-3+deb10u10
CVE ID : CVE-2023-25690 CVE-2023-27522
Debian Bug : 1032476
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.
For the detailed security status of apache2 please refer to
its security tracker page at:
