Microsoft Index Server idq.dll allows remote directory traversal
| http-indexserver-view-files (4232) |  Medium Risk |
Description:
Microsoft Index Server could allow a remote attacker to view files on the Web server. A vulnerability in the idq.dll file allows a remote attacker to search outside virtual directories by requesting a specially-crafted URL. Attackers can use this vulnerability to view any file on the Web server root drive, if they know or can guess the file name.
Platforms Affected:
- Microsoft, Index Server 2.0
Remedy:
Obtain the appropriate patch for your system, as listed in Microsoft Security Bulletin MS01-025, MS01-033, MS01-041, MS01-44, MS02-001 or MS02-018. See References.
In addition, ensure that your IDQ files restrict user input so that only .HTX files are capable of formatting the output. Some sample files do not sufficiently restrict user input. Sample files should always be removed from production servers.
