An attacker could exploit this vulnerability by sending crafted packets to an IP interface on an affected device. A successful exploit could allow the attacker to execute arbitrary code with root privileges and could cause process crashes resulting in a reload and DoS condition.","cvssScore":9.8,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-121"],"vendors":[],"products":[],"references":[{"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ngoam-rce-LWKQ4BU","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":{"summary":"This vulnerability allows an unauthenticated attacker to execute arbitrary code with root privileges or cause a Denial-of-Service (DoS) condition by sending crafted packets to an IP interface on an affected device.","exploitability":"Exploitation requires sending crafted packets to an enabled NGOAM feature, making it moderately hard to exploit.","blast_radius":"If exploited, the vulnerability could result in arbitrary code execution and a DoS condition, impacting the availability and integrity of the device.","remediation":"Disable the NGOAM feature or upgrade to the version 8.2(4) or later.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["rce","dos","network","unauth"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-10-08T08:40:47.651Z"}}
