MetricsAV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Apache HTTP Server version 2.4.33
Description The issue is related to the mod md challenge handler, which can dereference a NULL pointer when specially crafted HTTP requests are made, causing the child process to segfault. This can be used to cause a denial of service (DoS) to the server.
Recommendations For Apache HTTP Server version 2.4.33, update to version 2.4.34 to resolve the issue. As a temporary workaround, consider restricting access to the mod md module to minimize the risk of exploitation.
