Title: Lotus Notes Domino Webserver CGI Vulnerabilities
Severity: MODERATE
Description:
Three vulnerabilities have been discovered in the cgi handling done by Lotus Domino Server's Webserver component.
1: Path information can be obtained.
By submitting a request for a non-existant cgi, an attacker can determine the filesystem structure of the server. Example:
Requested URL:
http: //victimhost/cgi-bin/asdf
Response:
Error 500
Bad script request -- no variation of 'c:/notes/data/domino/cgi-bin/asdf' is executable
2: Anonymous access can not be disabled.
Even with anonymous access turned off on th eserver, it is still permitted for the cgi-bin directory.
3: Buffer overflow in cgi error handling
An overly long URL in a GET request, rooted in the cgi-bin directory, will crash the server. Not all long strings seem to work, but one that was tested and found to work was:
'GET /cgi-bin/[800 ','][4000 'a'] HTTP/1.0'
Affected Products:
- Lotus Domino Server 4.6.0
- Lotus Domino Server 4.6.0 .x
