Title: Allaire JRun Web Root Directory Disclosure Vulnerability
Severity: MODERATE
Description:
Allaire JRun is a development suite with JSP and Java Servlets for developing web applications.
Allaire JRun is prone to an information-disclosure vulnerability because it fails to handle malformed URLs properly. A remote attacker could access the contents under the webserver root directory.
Submitting a request for 'http://server/%3f.jsp' could cause JRun to reveal the contents within the web root. It's also possible to view the contents of any subdirectories along with ACL-protected resources.
The attacker could exploit this issue to obtain the source of known files residing on the host, including ASP files.
NOTE: This vulnerability was originally reported to work on Microsoft IIS hosts only, but other webservers (Apache, Jetty) have been reported vulnerable.
Affected Products:
- Macromedia JRun 3.0.0
- Macromedia JRun 3.1.0
