Cisco Secure Email Gateway SQL Injection Vulnerability
Qué es
A vulnerability in the email parsing of Cisco AsyncOS Software for Cisco Secure Email Gateway could allow an unauthenticated, remote attacker to execute arbitrary commands with root privileges on the underlying operating system.
This vulnerability is due to insufficient validation in the email parsing logic. An attacker could exploit this vulnerability by sending a crafted email message that contains malicious SQL statements through an affected device. A successful exploit could allow the attacker to execute arbitrary SQL statements, leading to command execution with root privileges on the underlying operating system.
CISA: Cisco AsyncOS software for Cisco Secure Email Gateway (SEG) contains a SQL injection vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary commands with root privileges on the underlying operating system.
Qué hacer
