Lil' HTTP Server "Referer" Cross Site Scripting Vulnerability
22 Apr. 2002
Summary
Lil' HTTP Server is a lightweight web server. The server has been found to contain a vulnerability that would allow an attacker inserting malicious JavaScript into the Referer tag to cause its execution upon the administrator's viewing of the log files.
Example:
Issuing the following request: GET / HTTP/1.0
Referer: <script>alert('vulnerable')</script>
Will cause the administrator to execute arbitrary JavaScript upon his viewing of the log files. Since they are run in the My Computer zone, they are executed at high privileges settings.
