<plugin_comment>I don't know how to detect the installed service pack accurately. Perhaps I will split this plugin in the future to detect the different flaws seperately.</plugin_comment>

<bug_description>The remote system is running BEA WebLogic 8.1 that is vulnerable to a HTTP response splitting attack. These attacks involve abusing various input validation flaws in these implementations to split HTTP responses into multiple parts in such a way that response data may be misrepresented to client users. Exploitation would occur by injecting variations of CR/LF sequences into parts of HTTP response headers that the attacker may control or influence. The general consequences of exploitation are that an attacker may misrepresent web content to the client, potentially enticing the user to trust the content and take actions based on this false trust. While the various implementations listed in the paper contribute to these attacks, this issue will most likely be exposed through web applications that do not properly account for CR/LF sequences when accepting user-supplied input that may be returned in server responses. This vulnerability could also aid in exploitation of cross-site scripting vulnerabilities.</bug_description>
<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. Additionally limit unwanted connections and communications with firewalling.</bug_solution>
