Detection & IOCsextracted from sources · hover to see the quote
- →The vulnerability is specific to Apache HTTP Server 2.4.53 with mod_sed enabled; detect by identifying httpd instances running version 2.4.53 with mod_sed loaded ↗
- →Monitor for abnormal memory allocation spikes or unexpected abort/crash of the httpd process, which may indicate exploitation of mod_sed with oversized input ↗
- →Check if mod_sed is loaded in httpd configuration; its presence on Apache 2.4.53 is a prerequisite for this vulnerability to be exploitable ↗
- ·mod_sed is disabled by default on Red Hat Enterprise Linux 7 and 8; systems where it has been explicitly enabled are at risk ↗
- ·httpd on Red Hat Enterprise Linux 6 is not affected because mod_sed is not available in that package ↗
- ·Only Apache HTTP Server version 2.4.53 is cited as vulnerable; fixed versions include 2.4.54 and later (e.g., Debian fixed in 2.4.54-1) ↗

Title: Apache HTTP Server regression
Summary: USN-5487-1 introduced a regression in Apache HTTP Server.
USN-5487-1 fixed several vulnerabilities in Apache. Unfortunately, that update introduced
a regression when proxying balancer manager connections in some configurations
on Ubuntu 14.04 ESM. This update reverts those changes till further fix.
We apologize for the inconvenience.
Original advisory details:
It was discovered that Apache HTTP Server mod_proxy_ajp incorrectly handled
certain crafted request. A remote attacker could possibly use this issue to
perform an HTTP Request Smuggling attack. (CVE-2022-26377)

USN-5487-1 fixed several vulnerabilities in Apache HTTP Server.
Unfortunately it caused regressions. USN-5487-2 reverted the
patches that caused the regression in Ubuntu 14.04 ESM for further
investigation. This update re-adds the security fixes for Ubuntu
14.04 ESM and fixes two different regressions: one affecting mod_proxy
only in Ubuntu 14.04 ESM and another in mod_sed affecting also Ubuntu 16.04 ESM
and Ubuntu 18.04 LTS.

CVE-2022-30522 [HIGH] CWE-770 httpd: mod_sed: DoS vulnerability
httpd: mod_sed: DoS vulnerability
If Apache HTTP Server 2.4.53 is configured to do transformations with mod_sed in contexts where the input to mod_sed may be very large, mod_sed may make excessively large memory allocations and trigger an abort.
A flaw was found in the mod_sed module of httpd. A very large input to the mod_sed module can result in a denial of service due to excessively large memory allocations.
Statement: The mod_sed module is disabled by default on Red Hat Enterprise Linux 7 and 8. The httpd package as shipped with Red Hat Enterprise Linux 6 is not affected by this flaw because the mod_sed module is not available.
Mitigation: Disabling mod_sed and restarting httpd will mitigate this flaw.
