CVE-2026-76461: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in Cisco Cisco Secure Email
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.
AI Analysis
Technical Summary
This vulnerability arises from improper neutralization of special elements in SQL commands within the email parsing logic of Cisco AsyncOS Software for Cisco Secure Email Gateway. An attacker can exploit this by sending a maliciously crafted email containing SQL statements, which the device improperly processes. This leads to arbitrary SQL execution and escalates to command execution with root privileges on the host OS, posing a severe security risk.
Potential Impact
An unauthenticated remote attacker can execute arbitrary commands with root privileges on the underlying operating system of the affected Cisco Secure Email Gateway device. This compromises confidentiality, integrity, and availability of the system, allowing full control over the device.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict exposure of the affected devices to untrusted networks and monitor for suspicious email traffic targeting the gateway.
