Bug affected | Squid up to 2.5.STABLE6 |
Bug not affected | Squid newer than 2.5.STABLE6 and newer or other proxy solutions |
Bug vulnerability class | Denial Of Service |
Bug description | The remote host seems to be running a Squid proxy. Squid up to 2.5.STABLE6 has a denial of service vulnerability in clientAbortBody(). An attacker may crash the remote proxy with a malicious website. |
Bug solution | The server should be deactivated or de-installed if not necessary. If this is not possible, you should upgrade the software to the latest version To make it harder to find the server the daemon could be configured to listen at another port (e.g. 8099). Try to prevent unwanted connection attempts by filtering traffic with firewalling. Alternation of the application banner can confuse an attacker and let him determine the wrong software. |
