| Description | Storage Concentrator (SC & SCVM) contains hardcoded credentials for numerous internal services embedded within a configuration file. While the credentials are stored in an encoded format, the encoding can be reversed to plaintext. The exposed credentials span a broad range of internal services, including database accounts, licensing, replication services, and third-party integrations, meaning successful exploitation of this vulnerability could provide an attacker with unauthorized access to multiple interconnected systems. |
