There’s a Nasty Security Hole in the Apache Webserver

Here a security hole, there a security hole, everywhere a security hole. This is a Denial of Service (DoS) attack in the https://httpd.apache.org/‘s https://httpd.apache.org/docs/2.4/mod/mod_sed.html.

In March 2022, https://nvd.nist.gov/vuln/detail/CVE-2022-23943, an Apache memory corruption vulnerability in mod_sed, was uncovered.
