| Detailed Description |
The IIS webserver contains a configuration flaw that allows the exposure of the global.asa file. An attacker can retrieve the content of global.asa which often contains some sensitive information such as SQL server's username and password.
Global.asa is a file maintained on the IIS server for each Active Server Page (ASP) program. The IIS server automatically processes the Global.asa file when either the IIS program starts and stops, or when a Web client starts and stops browser sessions that access the program's Web pages.
Typically, the global.asa file contains scripts to perform tasks, such as initializing application variables, connecting to databases, and sending cookies, etc.
This vulnerability may be caused by a missing ISAPI map of the .asa extension to asp.dll.
* Platforms Affected:
Microsoft IIS 4.0/5.0
