Bug affected | Apache prior 2.0.49 |
Bug not affected | Apache 2.0.49 and newer or other solutions |
Bug vulnerability class | Weak Encryption |
Bug description | The remote host is running an Apache web server. It has been reported that in Apache web server prior 2.0.49 fails to handle proxy and standard authentication credentials securely. The mod_disk_cache module is reported to store HTTP Hop-by-hop headers including user login and password information in plaintext format on disk. This issue could be used in conjunction with other possible vulnerabilities in a host to gain access to user authentication credentials. Successful exploitation of this issue may lead to further attacks agains vulnerable users of the affected host. |
Bug solution | If the web server is not used it should be de-installed or de-activated. Install the newest patch or bugfix to solve the problem or upgrade to the latest software version which is not vulnerable anymore. To make it harder to find the server the daemon could be configured to listen at another port (e.g. 8081). Alternation of the application banner can confuse an attacker and let him determine the wrong software. Additionally limit unwanted connections and communications with firewalling. |
