Apache 2.4.x < 2.4.34 Multiple Vulnerabilities
Medium Nessus Plugin ID 111788
SynopsisThe remote web server is affected by multiple vulnerabilities.
DescriptionAccording 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 Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
SolutionUpgrade to Apache version 2.4.34 or later.
