Insecure Trust of certificates using collision hash functions in Bitdefender Total Security HTTPS Scanning (VA-11239)



Description

A vulnerability has been identified in the Bitdefender Total Security HTTPS scanning functionality where the product incorrectly checks the site's certificate, which allows an attacker to make MITM SSL connections to an arbitrary site.
