22
FAUCET Score

CVE-2016-9892 describes a critical vulnerability in ESET Endpoint Antivirus and Endpoint Security for macOS (versions prior to 6.4.168.0) where the esets_daemon service fails to properly validate X.509 certificates from the edf.eset.com SSL server. This flaw allows a man-in-the-middle attacker to spoof the server using a self-signed certificate, potentially providing crafted responses to license activation requests. Rated with a CVSS score of 5.9 (Medium), this vulnerability has a high integrity impact and can be exploited remotely with high attack complexity, notably allowing for arbitrary code execution as root when combined with CVE-2016-0718. While there is no known active exploitation or public exploit code (Metasploit, Nuclei, ExploitDB), the vulnerability has garnered significant community discussion and media coverage, indicating its potential severity.
