An attacker could exploit this vulnerability by sending a crafted HTTP request to the NX-API of an affected device. A successful exploit could allow the attacker to execute arbitrary code with root privileges and could cause process crashes, which could result in a reload of the device and a 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-122"],"vendors":[],"products":[],"references":[{"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-napi-rce-r2shwu2j","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":{"summary":"This vulnerability allows an attacker to execute arbitrary code with root privileges or cause a DoS condition by sending a crafted HTTP request to the NX-API, posing a significant risk to the device's security and availability.","exploitability":"Exploitation requires sending a crafted HTTP request to the NX-API, which can be moderately difficult if the attacker has network access to the device.","blast_radius":"If exploited, the vulnerability could result in complete control of the device by the attacker, leading to potential data loss, system compromise, and denial of service.","remediation":"Upgrade to the latest version of Cisco NX-OS Software as specified in the vendor advisory.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["rce","dos","http","nx-api"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-10-08T08:40:46.208Z"}}
