CVE-2026-76461 is a critical vulnerability in Cisco AsyncOS Software for Cisco Secure Email Gateway. It arises from insufficient validation in the email parsing logic, allowing an unauthenticated remote attacker to send crafted emails containing malicious SQL statements. Successful exploitation can lead to arbitrary command execution with root privileges on the underlying operating system.
AI Analysis
Technical Summary
This vulnerability in Cisco AsyncOS Software for Cisco Secure Email Gateway is caused by improper validation in the email parsing component. An attacker can exploit this by sending specially crafted email messages that include malicious SQL statements. Exploitation results in arbitrary SQL execution, which escalates to arbitrary command execution with root privileges on the device's operating system. The CVSS 3.1 base score is 9.8, indicating a critical severity with network attack vector, no privileges required, and no user interaction needed.
Potential Impact
An attacker can remotely and without authentication execute arbitrary commands with root privileges on the underlying operating system of the affected Cisco Secure Email Gateway device. This can lead to full system compromise, data loss, or disruption of email gateway services.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch information is provided in the available data. Until a patch is available, monitor vendor communications for updates and consider applying any recommended temporary mitigations once disclosed.
