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: 3.6
SynopsisThe remote proxy server is affected by an information disclosure vulnerability.
DescriptionAccording to its banner, the version of Squid running on the remote host is 3.x after 3.1 and prior to 3.5.23, or 4.x prior to 4.0.17. It is, therefore, affected by an information disclosure vulnerability in the HTTP request processing component due to the incorrect HTTP conditional request handling. An unauthenticated, remote attacker can exploit this to disclose potentially sensitive information.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
SolutionUpgrade to Squid version 3.5.23 or 4.0.17 or later. Alternatively, apply the vendor-supplied patch.
