CVE-2026-22906 Details
Description
User credentials are stored using AES‑ECB encryption with a hardcoded key. An unauthenticated remote attacker obtaining the configuration file can decrypt and recover plaintext usernames and passwords, especially when combined with the authentication bypass.
A vulnerability exists in WAGO Industrial Managed Switch models 0852-1322 and 0852-1328, both running firmware through 2.64. User credentials are encrypted using AES-ECB with a hardcoded key, and an unauthenticated remote attacker who accesses the configuration file can decrypt and retrieve plaintext usernames and passwords. This vulnerability is particularly concerning when combined with an authentication bypass that has also been identified on these devices.
Users are advised to update their devices to firmware version 02.65.
