Vulnerability description

DayBreach CVE AI Research

CVE-2019-18988 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.

TeamViewer Desktop allows for bypass of remote-login access control because the same AES key is used for different customers' installations. If an attacker were to know this key, they could decrypt protected information stored in registry or configuration files or decryption of the Unattended Access password to the system (which allows for remote login to the system).
