Synopsis

Apache 2.4.x < 2.4.34 Multiple Vulnerabilities

Description

According to its banner, the version of Apache running on the remote host is 2.4.x prior to 2.4.34. It is, therefore, affected by the following vulnerabilities:

 - By specially crafting HTTP/2 requests, workers would be allocated 60 seconds longer than necessary, leading to worker exhaustion and a denial of service. (CVE-2018-1333)

 - By specially crafting HTTP requests, the mod_md challenge handler would dereference a NULL pointer and cause the child process to segfault. This could be used to DoS the server. (CVE-2018-8011)

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache version 2.4.34 or later.
