IMPACT:
Hijacking, Cross Site Scripting, Exposure of sensitive information,
DoS
WHERE:

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.
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.
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.
NOTE: This vulnerability only affects the Microsoft IIS connector.
4) A boundary error in the verbose logging module can be exploited to
cause the web server to crash.
Successful exploitation requires that "verbose" debug mode is enabled
for the JRun web server connectors (not enabled by default).
The vulnerabilities have been reported in versions 3.0, 3.1, and 4.0.
SOLUTION:
Apply patches.
