Short explanation

HCL BigFix Platform is affected by an intermediate CA certificate bundle issue when using Mozilla CA certificate bundles dated before 2026/10/20. This allows an on-path attacker to impersonate servers and tamper with downloaded files.

Why does it matter?

On-path attackers can impersonate remote servers and tamper with files downloaded by the application, leading to confidentiality and integrity breaches.

What should be done?

  • Using certificate bundle version 2026/10/20 or later
  • Using BES Support v1520 or later
  • Following the vendor advisory
Note on uncertainty

Show the technical text from the sources

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.
