| Detailed Description |
According to its banner, the version of Squid running on the remote host is 4.x prior to 4.0.9. It is, therefore, affected by multiple vulnerabilities :
- An assertion fault exists in file esi/Esi.cc that is triggered when handling ESI responses. An unauthenticated, remote attacker can exploit this, via an HTTP server that uses specially crafted Edge Side Includes (ESI), to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-4052)
- A flaw exists in file esi/Esi.cc due to improper validation of user-supplied input when handling ESI responses. An unauthenticated, remote attacker can exploit this, via specially crafted ESI responses, to disclose sensitive stack layout information.
(CVE-2016-4053)
- A buffer overflow condition exists in file esi/Esi.cc due to improper validation of user-supplied input when handling ESI responses. An unauthenticated, remote attacker can exploit this, via specially crafted ESI responses, to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-4054)
* Note: This check solely relied on the version number of the remote Squid Web Proxy Cache server to assess this vulnerability, so this might be a false positive.
