What is CVE-2020-15931?

A vulnerability in Netwrix Account Lockout Examiner versions prior to 5.1 allows remote attackers to capture the Net-NTLMv1/v2 authentication challenge hash of the Domain Administrator configured in the product. By triggering a Kerberos Pre-Authentication Failed event on a Domain Controller, unauthorized users can potentially exploit this weakness to gain sensitive authentication data, posing a risk to the security of IT environments.

Exploit Proof of Concept (PoC)
