A vulnerability in the web-based management interface of Cisco ATA 190 Series Multiplatform Analog Telephone Adapter firmware could allow an authenticated, local attacker with low privileges to view passwords on an affected device. This vulnerability is due to incorrect sanitization of HTML content from an affected device. A successful exploit could allow the attacker to view passwords that belong to other users.
The 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.
The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.
The product stores sensitive information without properly limiting read or write access by unauthorized actors.
