Description:
Multiple vulnerabilities have been reported in JRun Server, which can be exploited by malicious people to hijack an authenticated user's session, conduct cross-site scripting attacks, disclose sensitive information, and cause a DoS (Denial of Service).
1) An implementation error in the generation and handling of JSESSIONIDs can be exploited to hijack an authenticated user's session.
This vulnerability affects version 4.0.
2) A cross-site scripting and session handling vulnerability in the JRun Management Console can be exploited to execute arbitrary HTML and script code in a user's browser session in context of a vulnerable site, or hijack an authenticated user's session.
This vulnerability affects version 4.0.
3) An URL parsing error can e.g. be exploited to show the source of any file such as script files inside the web root by appending ";.cfm" to the end of an URL.
This vulnerability affects version 4.0.
NOTE: This vulnerability only affects the Microsoft IIS connector.
4) A boundary error in the mod_jrun Apache module within the "WriteToLog()" function can be exploited to cause a buffer overflow via certain overly long headers (e.g. the "Content-Type" header).
Successful exploitation allows execution of arbitrary code, but requires that "verbose" debug mode is enabled for the JRun web server connectors (not enabled by default).
The vulnerability has been reported in version 3.0, 3.1, and 4.0.
Solution:
Apply patches.
