Bug affected | Apache prior 1.3.32 |
Bug not affected | Apache 1.3.32 and newer or other solutions |
Bug vulnerability class | Buffer Overflow |
Bug description | The remote host is running an Apache web server. It has been reported that in Apache web server prior 1.3.32 fails in some cases to handle htpasswd runs. Exploitation of this buffer overflow conditions may result in the execution of arbitrary code. |
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. |
