Name of the Vulnerable Software and Affected Versions Bitdefender Total Security (affected versions not specified)

Description A flaw has been identified in the HTTPS scanning functionality where the software fails to properly validate website certificates. Specifically, if a site certificate lacks the "Server Authentication" specification in the Extended Key Usage extension, the product does not verify the certificate's compliance with the site, deeming such certificates as valid. This could allow an attacker to perform a Man-in-the-Middle (MITM) attack, intercepting and potentially altering communications between the user and the website.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
