A vulnerability has been discovered in Cisco Secure Email Gateway that could allow for remote code execution. Cisco Secure Email Gateway is an email security product that uses signature analysis and machine learning to identify and block malicious emails before they reach recipients inboxes. Successful exploitation could allow the attacker to replace any file on the underlying file system. The attacker could then perform any of the following actions: add users with root privileges, modify the device configuration, execute arbitrary code, or cause a permanent denial of service (DoS) condition on the affected device.
