Description
BigFix Platform uses Mozilla CA certificate bundle (PEM). Versions of the bundle dated before 2026/10/20 still trust certificates whose private keys have been compromised. When BigFix Platform validates servers using such a bundle, an on-path attacker can impersonate remote servers and tamper with files downloaded by the application. The issue is resolved by using bundle version 2026/10/20 or later. The fixed bundle is available starting from BES Support v1520.
