Storage Concentrator: Use of Hard-coded Credentials
CVE-2026-50110 is a critical-severity use of hard-coded credentials vulnerability in Storage Concentrator from StoneFly, with a CVSS 3.1 base score of 9.2 out of 10. It can be exploited with local access to the system by an unauthenticated attacker, without any action from a user. The record lists version 8.0.4.26 as the first without the flaw, so updating Storage Concentrator to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.18% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Storage Concentrator to 8.0.4.26 or a later version.
- Update Storage Concentrator Virtual Machine to 8.0.4.26 or a later version.

Official 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.

The underlying weakness: Use of Hard-coded Credentials
The product contains hard-coded credentials, such as a password or cryptographic key.
How developers prevent this class of flaw
- For outbound authentication: store passwords, keys, and other credentials outside of the code in a strongly-protected, encrypted configuration file or database that is protected from access by all outsiders, including other local users on the same system. Properly protect the key (CWE-320). If you cannot use encryption to protect the file, then make sure that the permissions are as restrictive as possible. In Windows environments, the Encrypted File System (EFS) may provide some protection.
- For inbound authentication: Rather than hard-code a default username and password, key, or other authentication credentials for first time logins, utilize a first login mode that requires the user to enter a unique strong password or key.
- If the product must contain hard-coded credentials or they cannot be removed, perform access control checks and limit which entities can access the feature that requires the hard-coded credentials. For example, a feature might only be enabled through the system console instead of through a network connection.
