Traffic decryption via TrustAllCerts and fixed DES keys
Published Jun 4, 2026 · Updated Jun 4, 2026
Improper TLS validation in Acer Connect M6E firmware M6E_AI_1.00.000019 and earlier allows man-in-the-middle attackers to decrypt traffic. TrustAllCerts routines accept untrusted certificates instead of performing standard certificate validation, while hard-coded DES keys make protected traffic decryptable. An attacker must intercept a device network connection; successful exploitation exposes traffic contents and can undermine traffic integrity.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
