Subject: Re: Bug found in ht://Dig htsearch CGI 
CC: htdig-general@lists.sourceforge.net, "htdig3-dev" <htdig-

* Name: ht://Dig (htsearch CGI)

* Versions affected: 3.1.0b2 and more recent, including 3.1.5 and 3.2.0b3

* Vulnerability:   (Potential remote exposure. Denial of Service.)

* Details:
The htsearch CGI runs as both the CGI and as a command-line program. 
The command-line program accepts the -c [filename] to read in an 
alternate configuration file. On the other hand, no filtering is done 
to stop the CGI program from taking command-line arguments, so a 
remote user can force the CGI to stall until it times out (resulting 
in a DOS) or read in a different configuration file.

For a remote exposure, a specified configuration file would need to 
be readable via the webserver UID, e.g. via anonymous FTP with upload 
enabled or samba world-readable log files are the possible targets) 
to potentially retrieve files readable by the webserver UID.
nothing_found_file: /path/to/the/file/we/steal

* Potential exploit:

* Fix:
Upgrade to current prerelease versions of 3.1.6 or 3.2.0b4, or apply 
attached patches.

Prerelease versions are available from
