Synopsis
The remote proxy server is affected by multiple vulnerabilities.Description
According to its banner, the version of Squid running on the remote host is 3.x prior to 3.5.28, or 4.x prior to 4.0.23. It is, therefore, affected by multiple vulnerabilities:- A denial of service (DoS) vulnerability exists in the ESI response processing component due to incorrect pointer handling.
A remote attacker controlled server can exploit this issue, via a crafted ESI response, to cause a denial of service for all clients accessing the Squid service (CVE-2018-1000024)
- A denial of service (DoS) vulnerability exists in the HTTP message processing component due to incorrect pointer handling.
An unauthenticated remote attacker can exploit this issue, via a crafted HTTP request, to cause a denial of service for all clients accessing the Squid service (CVE-2018-1000027)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
Solution
Upgrade to Squid version 3.5.28 or 4.0.23 or later. Alternatively, apply the vendor-supplied patch.See Also
