New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 2.2
SynopsisThe remote web server is affected by a denial of service vulnerability.
DescriptionAccording to its banner, the version of Apache 2.2.x running on the remote host is prior to 2.2.21. It is, therefore, potentially affected by a denial of service vulnerability. An error exists in the 'mod_proxy_ajp' module that can allow specially crafted HTTP requests to cause a backend server to temporarily enter an error state. This vulnerability only occurs when 'mod_proxy_ajp' is used along with 'mod_proxy_balancer'.
Note that Nessus did not actually test for the flaws but instead has relied on the version in the server's banner.
SolutionUpgrade to Apache version 2.2.21 or later.
