CVE-2025-52627

System file modification via writable root filesystem

Published Feb 3, 2026 · Updated Feb 3, 2026

Incorrect root-filesystem permissions in HCL AION 2.0 allow physically proximate attackers to modify critical system files. The deployment mounts its root filesystem with write access instead of enforcing a read-only mount; HCL has not identified the affected container or manifest. Exploitation requires physical access, low privileges, high complexity, and user interaction, and the reported consequence is unauthorized file modification without service interruption.
