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.

Why it matters

Internet-facing
Not identified as a common internet-facing category
Exploitation likelihood
high
  • Remotely exploitable over the network — no physical or local access required
  • Low attack complexity — no special conditions needed to exploit
  • No authentication required
  • No user interaction needed — can be exploited automatically
Recommended mitigation

Apply the vendor patch as soon as it's available or already released.

This analysis is generated from structured CVSS vector data, CISA KEV cross-referencing, and vendor/product category rules — not a manual expert review. Treat it as a starting point, not a substitute for your own assessment.
