What is CVE-2011-4968?

The nginx HTTP proxy module has a vulnerability that stems from its failure to authenticate the peer identity of HTTPS origin servers. This oversight exposes the application to potential man-in-the-middle attacks, allowing malicious actors to intercept, modify, or relay information between clients and the server without detection. It is crucial for users of affected nginx versions to implement proper security controls and updates to mitigate this risk.
