rConfig Core 8.2.3 before 8.2.13 contains an information disclosure vulnerability that allows authenticated users to retrieve cleartext SSH, Telnet, and enable passwords for managed devices through the device-credentials API due to automatic decryption on read and missing authorization checks. Attackers can request GET /api/device-credentials, GET /api/device-credentials/{id}, or the external GET /api/v1/device-credentials endpoint, which authenticates any valid token as the seeded administrator account, to statelessly exfiltrate all stored plaintext device credentials. rConfig Pro is not affected.
