Description

A vulnerability has been identified in SCALANCE X-200 switch family (incl. SIPLUS NET variants) (All Versions < V5.2.4), SCALANCE X-200IRT switch family (incl. SIPLUS NET variants) (All versions < V5.5.0), SCALANCE X-300 switch family (incl. X408 and SIPLUS NET variants) (All versions < V4.1.3), SCALANCE X-414-3E (All versions). The affected devices store passwords in a recoverable format. An attacker may extract and recover device passwords from the device configuration. Successful exploitation requires access to a device configuration backup and impacts confidentiality of the stored passwords.

• CWE-257Storing Passwords in a Recoverable FormatThe storage of passwords in a recoverable format makes them subject to password reuse attacks by malicious users. In fact, it should be noted that recoverable encrypted passwords provide no significant benefit over plaintext passwords since they are subject not only to reuse by malicious attackers but also by malicious insiders. If a system administrator can recover a password directly, or use a brute force search on the available information, the administrator can use the password on other accounts.
• CWE-522Insufficiently Protected CredentialsThe product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.
