Exploit for Microsoft IIS ASP Multiple Extensions Security Bypass 5.x/6.x
The Vulnerability discovered in Microsoft Internet Information Services (IIS) can be exploited by malicious people to potentially bypass certain security restrictions and compromise a vulnerable system. The vulnerability is caused due to the web server incorrectly executing e.g. ASP code included in a file having multiple extensions separated by ';', if the first extension is equal to '.asp' (e.g. 'file.asp;.jpg'). This can be exploited to potentially upload and execute arbitrary ASP code via a third-party application using file extensions to restrict uploaded file types.
Mitigation:
Restrict access to the web server to trusted IP addresses and networks, and ensure that all applications are kept up to date with the latest security patches.
