Cisco Secure Email and Web Manager and Secure Web Appliance Command Injection Vulnerability

Vulnerability

A vulnerability in the web-based management interface of Cisco AsyncOS Software for Cisco Secure Email Gateway and Cisco Secure Web Appliance could allow an authenticated, remote attacker to perform command injection attacks against an affected device. The attacker must have valid administrative credentials. This vulnerability is due to insufficient validation of XML configuration files by an affected device. An attacker could exploit this vulnerability by uploading a crafted XML configuration file. [1]

Exploitation

To exploit, the attacker must have valid admin credentials and upload a crafted XML configuration file via the web interface. The device fails to validate the XML properly, allowing injection of arbitrary commands into the underlying OS with root privileges. [1]

Impact

Successful exploitation allows the attacker to execute arbitrary commands on the underlying operating system with root privileges, leading to full system compromise, data disclosure, or denial of service. [1]

Mitigation

Cisco has released software updates that address this vulnerability. There are no workarounds. Users should upgrade to the latest fixed version. [1]
