According to its banner, the version of Apache 2.4.x running on the remote host is a version prior to 2.4.8. It is, therefore, affected by the following vulnerabilities :
A flaw exists with the βmod_davβ module that is caused when tracking the length of CDATA that has leading white space. A remote attacker with a specially crafted DAV WRITE request can cause the service to stop responding.
(CVE-2013-6438)
A flaw exists in βmod_log_configβ module that is caused when logging a cookie that has an unassigned value. A remote attacker with a specially crafted request can cause the service to crash. (CVE-2014-0098)
Note that Nessus did not actually test for these issues, but instead has relied on the version in the serverβs banner.
