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: 5.1
SynopsisThe remote proxy server is affected by multiple vulnerabilities
DescriptionAccording to its banner, the version of Squid running on the remote host is 2.x prior to 4.13 or 5.x prior to 5.0.4. It is,therefore, affected by multiple vulnerabilities:
- An input-validation flaw exists related to handling HTTP and HTTPS traffic that allows HTTP request splitting leading to cache poisoning. (CVE-2020-15810)
- An input-validation flaw exists related to handling HTTP and HTTPS traffic that allows HTTP request smuggling leading to cache poisoning. (CVE-2020-15811)
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 4.13 or 5.0.4 or later.
