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: 6.7
SynopsisThe remote web server may be affected by multiple vulnerabilities.
DescriptionAccording to its banner, the version of Apache 2.4.x running on the remote host is prior to 2.4.10. It is, therefore, affected by the following vulnerabilities :
- A flaw exists in the 'mod_proxy' module that may allow an attacker to send a specially crafted request to a server configured as a reverse proxy that may cause the child process to crash. This could potentially lead to a denial of service attack. (CVE-2014-0117)
- A flaw exists in the 'mod_deflate' module when request body decompression is configured. This could allow a remote attacker to cause the server to consume significant resources. (CVE-2014-0118)
- A flaw exists in the 'mod_status' module when a publicly accessible server status page is in place.
This could allow an attacker to send a specially crafted request designed to cause a heap buffer overflow. (CVE-2014-0226)
- A flaw exists in the 'mod_cgid' module in which CGI scripts that did not consume standard input may be manipulated in order to cause child processes to hang. A remote attacker may be able to abuse this in order to cause a denial of service.
- A flaw exists in WinNT MPM versions 2.4.1 to 2.4.9 when using the default AcceptFilter. An attacker may be able to specially craft requests that create a memory leak in the application and may eventually lead to a denial of service attack. (CVE-2014-3523)
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 2.4.10 or later. Alternatively, ensure that the affected modules are not in use.
