HTTP: .NET XML Digital Signature Spoofing
This signature detects attempts to exploit a known vulnerability in Microsoft's .NET Framework. An attacker can successfully exploit the vulnerability and modify the contents of an XML file without invalidating the file's signature and could gain access to endpoint functions authenticated user.
Extended Description
The Common Language Runtime (CLR) in Microsoft .NET Framework 2.0 SP2, 3.5, 3.5.1, 4, and 4.5 does not properly check signatures, which allows remote attackers to make undetected changes to signed XML documents via unspecified vectors that preserve signature validity, aka "XML Digital Signature Spoofing Vulnerability."
