CVE Reference: GENERIC-MAP-NOMATCH
(Links to External Site)
|
Date: Sep 24 2004
|
Impact: Disclosure of authentication information, Disclosure of system information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information, Not specified, User access via network
|
Fix Available: Yes
Exploit Included: Yes
Vendor Confirmed: Yes
|
Version(s): 3.0, 3.1, and 4.0
|
Description: Several vulnerabilities were reported in Macromedia's JRun server. A remote user can conduct cross-site scripting and session-fixation
attacks. A remote user can also view source code for certain types of files on the system. The impact of a buffer overflow was
not specified.
The vendor reported that an implementation error in JRun 4.0 in the generation and processing of JSESSIONIDs may allow a remote user
to hijack a session or conduct session-fixation attacks.
Some input validation flaws in the JRUn 4.0 Management Console allow
cross-site scripting attacks and session-fixation attacks. A remote user can cause arbitrary scripting code to be executed by the
target user's browser. The code will originate from the site running the JRun software and will run in the security context of that
site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated
with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as
the target user.
A remote user can submit a specially crafted request ending with the ';.cfm' string to cause the target JRun
server to show the source for certain files on the system. Files that are not associated with Macromedia extensions (e.g., '.php',
'.asp', '.pl') are affected.
It is also reported that if the 'verbose' logging debug mode is enabled on the JRun web server connectors,
a remote user can trigger a buffer overflow. In the default setting for verbose logging (disabled), the system is not vulnerable
to the buffer overflow. The impact was not specified.
The severity rating is critical.
Macromedia credits iDEFENSE with reporting
the view source ";.cfm" and connector buffer overflow vulnerabilities, @Stake with reporting the weak JSESSIONID generation vulnerability,
and Acros with reporting the "Unsanitized JRun Session ID Cookie Allows Modifying Server Response" vulnerability, a cross-site scripting
vulnerability, and a session fixation vulnerability in the JRun Management Console.

Impact: A remote user can hijack a user session.
A remote user can access the target user's cookies (including authentication cookies),
if any, associated with the site running the JRun software, access data recently submitted by the target user via web form to the
site, or take actions on the site acting as the target user.
A remote user can view the source code of certain types of files
on the system.
The impact was not specified for the buffer overflow vulnerability.

> MPSB04-08 - Cumulative Security Patch available for JRun server
JRun 3.0, 3.1, and 4.0 are affected.
An implementation error in JRun 4.0 in the generation and processing of JSESSIONIDs
may allow a remote user to hijack a session or conduct session-fixation attacks.
Some input validation flaws in the JRUn 4.0 Management Console allow cross-site
scripting attacks and session-fixation attacks.
A remote user can submit a specially crafted request ending with the ';.cfm' string to
cause the underlying JRun server to show the source for certain files on the system.
Files that are not associated with Macromedia extensions (e.g., '.php', '.asp', '.pl') are affected.
It is also reported that if the 'verbose' logging debug mode is enabled on the JRun web
server connectors, a remote user can trigger a buffer overflow. In the default setting
for verbose logging (disabled), the system is not vulnerable to the buffer overflow.
The impact was not specified.
The severity rating is critical.

overflow vulnerabilities, @Stake with reporting the weak JSESSIONID generation
vulnerability, and Acros with reporting the "Unsanitized JRun Session ID Cookie Allows
Modifying Server Response" vulnerability, a cross-site scripting vulnerability, and a
session fixation vulnerability in the JRun Management Console.
