EulerOS 2.0 SP8 : squid (EulerOS-SA-2020-2323)
medium Nessus Plugin ID 142152
Synopsis
The remote EulerOS host is missing multiple security updates.Description
According to the versions of the squid package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :- An issue was discovered in Squid before 4.13 and 5.x before 5.0.4. Due to incorrect data validation, HTTP Request Splitting attacks may succeed against HTTP and HTTPS traffic. This leads to cache poisoning. This allows any client, including browser scripts, to bypass local security and poison the browser cache and any downstream caches with content from an arbitrary source. Squid uses a string search instead of parsing the Transfer-Encoding header to find chunked encoding.
This allows an attacker to hide a second request inside Transfer-Encoding: it is interpreted by Squid as chunked and split out into a second request delivered upstream. Squid will then deliver two distinct responses to the client, corrupting any downstream caches.(CVE-2020-15811)
- Squid before 4.4, when SNMP is enabled, allows a denial of service (Memory Leak) via an SNMP packet.(CVE-2018-19132)
- Squid before 4.4 has XSS via a crafted X.509 certificate during HTTP(S) error page generation for certificate errors.(CVE-2018-19131)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
