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.","published":"2026-09-14T17:17:51.000Z","lastModified":"2026-09-15T12:47:32.000Z","status":"Analyzed","sourceIdentifier":"psirt@cisco.com","cvss":{"version":"3.1","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-89"],"affected":["cisco/asyncos"],"epss":{"score":0.29543,"percentile":0.98185,"date":"2026-10-30","history":[{"date":"2026-09-25","score":0.28269,"percentile":0.98053},{"date":"2026-10-13","score":0.29543,"percentile":0.98157}]},"kev":{"listed":true,"dateAdded":"2026-09-14","dueDate":"2026-09-17","knownRansomwareCampaignUse":"Unknown","notes":"Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes).
