Technical description

The strong name (SN) implementation in Microsoft .NET Framework 2.0.50727 relies on the digital signature Public Key Token embedded in the pathname of a DLL file instead of the digital signature of this file itself, which makes it easier for attackers to bypass Global Assembly Cache (GAC) and Code Access Security (CAS) protection mechanisms, aka MSRC ticket MSRC8566gs.

Remediation

Check the references section for vendor advisories and patches from microsoft. Update .net_framework to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
