Liteserve Buffer Overflow in Handling Server's Log. ================================================= PROGRAM: Liteserve HOMEPAGE:http://www.cmfperception.com/liteserve.html VULNERABLE VERSIONS: 2.2 and below DESCRIPTION ================================================= LiteServe is a powerful, full-featured Web, Mail, FTP, and Telnet server. This server software is perfect for personal websites or commercial sites with high traffic demands and multiple domains. DETAILS ================================================= If LiteServe receives a request with a long file name like this: GET /aaaaaaaaaaaaaaaaaaaaaa...htm HTTP/1.0 (the number of "a" must be around 1 to 3 thousands, use a fuzzer like SPike to duplicate the exploit) will cause a buffer overflow when the webmaster sees the server log and click on the request using LiteServe interface. WORKAROUND ================================================= Don't use the LiteServe Interface to view the server's log. Apply the patch from vendor.
