Details
A vulnerability in the Cisco Discovery Protocol feature of Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to execute arbitrary code as root or cause a denial of service (DoS) condition on an affected device. The vulnerability exists because of insufficiently validated Cisco Discovery Protocol packet headers. An attacker could exploit this vulnerability by sending a crafted Cisco Discovery Protocol packet to a Layer 2-adjacent affected device. A successful exploit could allow the attacker to cause a buffer overflow that could allow the attacker to execute arbitrary code as root or cause a DoS condition on the affected device. Note: Cisco Discovery Protocol is a Layer 2 protocol. To exploit this vulnerability, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent). Note: This vulnerability is different from the following Cisco FXOS and NX-OS Software Cisco Discovery Protocol vulnerabilities that Cisco announced on Feb. 5, 2020: Cisco FXOS, IOS XR, and NX-OS Software Cisco Discovery Protocol Denial of Service Vulnerability and Cisco NX-OS Software Cisco Discovery Protocol Remote Code Execution Vulnerability.

description_data: [ { lang: "en", value: "A vulnerability in the Cisco Discovery Protocol feature of Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to execute arbitrary code as root or cause a denial of service (DoS) condition on an affected device. The vulnerability exists because of insufficiently validated Cisco Discovery Protocol packet headers. An attacker could exploit this vulnerability by sending a crafted Cisco Discovery Protocol packet to a Layer 2-adjacent affected device. A successful exploit could allow the attacker to cause a buffer overflow that could allow the attacker to execute arbitrary code as root or cause a DoS condition on the affected device. Note: Cisco Discovery Protocol is a Layer 2 protocol. To exploit this vulnerability, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent). Note: This vulnerability is different from the following Cisco FXOS and NX-OS Software Cisco Discovery Protocol vulnerabilities that Cisco announced on Feb. 5, 2020: Cisco FXOS, IOS XR, and NX-OS Software Cisco Discovery Protocol Denial of Service Vulnerability and Cisco NX-OS Software Cisco Discovery Protocol Remote Code Execution Vulnerability.", }, ], }, problemtype: { problemtype_data: [ { description: [ { lang: "en", value: "CWE-20", }, ], }, ], }, references: { reference_data: [ { name: "20200226 Cisco FXOS and NX-OS Software Cisco Discovery Protocol Arbitrary Code Execution and Denial of Service Vulnerability", refsource: "CISCO", tags: [ "Vendor Advisory", ], url: "https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200226-fxos-nxos-cdp", }, ], }, }, impact: { baseMetricV2: { acInsufInfo: false, cvssV2: { accessComplexity: "LOW", accessVector: "ADJACENT_NETWORK", authentication: "NONE", availabilityImpact: "COMPLETE", baseScore: 8.3, confidentialityImpact: "COMPLETE", integrityImpact: "COMPLETE", vectorString: "AV:A/AC:L/Au:N/C:C/I:C/A:C", version: "2.0", }, exploitabilityScore: 6.5, impactScore: 10, obtainAllPrivilege: false, obtainOtherPrivilege: false, obtainUserPrivilege: false, severity: "HIGH", userInteractionRequired: false, }, baseMetricV3: { cvssV3: { attackComplexity: "LOW", attackVector: "ADJACENT_NETWORK", availabilityImpact: "HIGH", baseScore: 8.8, baseSeverity: "HIGH", confidentialityImpact: "HIGH", integrityImpact: "HIGH", privilegesRequired: "NONE", scope: "UNCHANGED", userInteraction: "NONE", vectorString: "CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", version: "3.1", }, exploitabilityScore: 2.8, impactScore: 5.9, }, }, lastModifiedDate: "2023-04-20T15:27Z", publishedDate: "2020-02-26T17:15Z", }, }, }
