GEN:SID | 1:1042 |
Message | WEB-IIS view source via translate header |
Summary | This event is generated when an attempt is made to craft a URL containing the text 'Translate: f' in an attempt to view file source code.
|
Impact | Intelligence gathering. This attack may permit disclosure of the source code of files not normally available for viewing.
|
Detailed Information | Microsoft Internet Information Services (IIS) 5.0 contains scripting engines to support various advanced files types such as .ASP and .HTR files. This permits the execution of server-side processing. IIS determines which scripting engine is appropriate to use depending on the file extension. If an attacker crafts a URL request ending in 'Translate: f' and followed by a slash '/', IIS fails to send the file to the appropriate scripting engine for processing. Instead, it returns the source code of the referenced file to the browser.
|
Affected Systems | Microsoft IIS 5.0
|
Attack Scenarios | An attacker can craft a URL to include the 'Translate: f' and followed by a '/' to disclose source code on the vulnerable server.
|
Ease of Attack | Simple. Attack scripts are freely available.
|
Corrective Action | Apply the appropriate vendor supplied patch.
