Technical details
The vulnerability stems from weak password policy enforcement in easyE4, enabling offline dictionary or brute-force attacks against captured password hashes. An attacker must first obtain a password hash, potentially via CVE-2026-41020 or similar disclosure, then conduct computation-intensive cracking locally without network interaction. Successful exploitation results in plaintext credential recovery and system access.
