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: 5.9
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 4.12 or 5.x prior to 5.0.3. It is,therefore, affected by multiple vulnerabilities:
- Multiple denial of service (DoS) vulnerabilities exist in the SMP cache and TLS handshake implementations of Squid. An unauthenticated, remote attacker can exploit these issues, by sending specially crafted requests to an affected instance, to impose a DoS condition on the application (CVE-2020-14058, CVE-2020-14059).
- A cache poisoning vulnerability exists in Squid due to insufficient user input validation. An authenticated, remote attacker can exploit this issue, to affect the integrity of the contents returned to users from the cache (CVE-2020-15049).
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 4.12 or 5.0.3 or later.
