Multiple vulnerabilities in Cisco ATA 190 Series Analog Telephone Adapter firmware, both on-premises and multiplatform, could allow a remote attacker to delete or change the configuration, execute commands as the root user, conduct a cross-site scripting (XSS) attack against a user of the interface, view passwords, conduct a cross-site request forgery (CSRF) attack, or reboot the device. For more information about these vulnerabilities, see the Details ["#details"] section of this advisory. Cisco has released firmware updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities. However, there is a mitigation that addresses some of these vulnerabilities for Cisco ATA 191 on-premises firmware only.

A vulnerability in the CLI of Cisco ATA 190 Series Analog Telephone Adapter firmware could allow an authenticated, local attacker with high privileges to execute arbitrary commands as the root user. This vulnerability exists because CLI input is not properly sanitized. An attacker could exploit this vulnerability by sending malicious characters to the CLI. A successful exploit could allow the attacker to read and write to the underlying operating system as the root user.

Ein Angreifer kann mehrere Schwachstellen im Cisco Analog Telephone Adaptor ATA 191 und ATA 192 ausnutzen, um seine Privilegien zu erhöhen, beliebigen Code auszuführen, vertrauliche Informationen offenzulegen, einen Cross-Site-Scripting-Angriff durchzuführen oder einen Denial-of-Service-Zustand zu erzeugen.
