Summary
A vulnerability in the logic that handles access control to one of the hardware components in Cisco's proprietary Secure Boot implementation could allow an authenticated, local attacker to write a modified firmware image to the component. This vulnerability affects multiple Cisco products that support hardware-based Secure Boot functionality. The vulnerability is due to an improper check on the area of code that manages on-premise updates to a Field Programmable Gate Array (FPGA) part of the Secure Boot hardware implementation. An attacker with elevated privileges and access to the underlying operating system that is running on the affected device could exploit this vulnerability by writing a modified firmware image to the FPGA. A successful exploit could either cause the device to become unusable (and require a hardware replacement) or allow tampering with the Secure Boot verification process, which under some circumstances may allow the attacker to install and boot a malicious software image. An attacker will need to fulfill all the following conditions to attempt to exploit this vulnerability: Have privileged administrative access to the device. Be able to access the underlying operating system running on the device; this can be achieved either by using a supported, documented mechanism or by exploiting another vulnerability that would provide an attacker with such access. Develop or have access to a platform-specific exploit. An attacker attempting to exploit this vulnerability across multiple affected platforms would need to research each one of those platforms and then develop a platform-specific exploit. Although the research process could be reused across different platforms, an exploit developed for a given hardware platform is unlikely to work on a different hardware platform.

Summary
A vulnerability in the Virtual Private LAN Service (VPLS) code of Cisco IOS 15.0 through 15.4 for Cisco Catalyst 6800 Series Switches could allow an unauthenticated, adjacent attacker to cause a C6800-16P10G or C6800-16P10G-XL type line card to crash, resulting in a denial of service (DoS) condition. The vulnerability is due to a memory management issue in the affected software. An attacker could exploit this vulnerability by creating a large number of VPLS-generated MAC entries in the MAC address table of an affected device. A successful exploit could allow the attacker to cause a C6800-16P10G or C6800-16P10G-XL type line card to crash, resulting in a DoS condition. This vulnerability affects Cisco Catalyst 6800 Series Switches that are running a vulnerable release of Cisco IOS Software and have a Cisco C6800-16P10G or C6800-16P10G-XL line card in use with Supervisor Engine 6T. To be vulnerable, the device must also be configured with VPLS and the C6800-16P10G or C6800-16P10G-XL line card needs to be the core-facing MPLS interfaces. Cisco Bug IDs: CSCva61927.

Summary
A vulnerability in the logic that handles access control to one of the hardware components in Cisco's proprietary Secure Boot implementation could allow an authenticated, local attacker to write a modified firmware image to the component. This vulnerability affects multiple Cisco products that support hardware-based Secure Boot functionality. The vulnerability is due to an improper check on the area of code that manages on-premise updates to a Field Programmable Gate Array (FPGA) part of the Secure Boot hardware implementation. An attacker with elevated privileges and access to the underlying operating system that is running on the affected device could exploit this vulnerability by writing a modified firmware image to the FPGA. A successful exploit could either cause the device to become unusable (and require a hardware replacement) or allow tampering with the Secure Boot verification process, which under some circumstances may allow the attacker to install and boot a malicious software image. An attacker will need to fulfill all the following conditions to attempt to exploit this vulnerability: Have privileged administrative access to the device. Be able to access the underlying operating system running on the device; this can be achieved either by using a supported, documented mechanism or by exploiting another vulnerability that would provide an attacker with such access. Develop or have access to a platform-specific exploit. An attacker attempting to exploit this vulnerability across multiple affected platforms would need to research each one of those platforms and then develop a platform-specific exploit. Although the research process could be reused across different platforms, an exploit developed for a given hardware platform is unlikely to work on a different hardware platform.

hardware components in Cisco's proprietary Secure Boot implementation could allow an authenticated, local attacker to write a modified firmware image to the component. This vulnerability affects multiple Cisco products that support hardware-based Secure Boot functionality. The vulnerability is due to an improper check on the area of code that manages on-premise updates to a Field Programmable Gate Array (FPGA) part of the Secure Boot hardware implementation. An attacker with elevated privileges and access to the underlying operating system that is running on the affected device could exploit this vulnerability by writing a modified firmware image to the FPGA. A successful exploit could either cause the device to become unusable (and require a hardware replacement) or allow tampering with the Secure Boot verification process, which under some circumstances may allow the attacker to install and boot a malicious software image. An attacker will need to fulfill all the following conditions to attempt to exploit this vulnerability: Have privileged administrative access to the device. Be able to access the underlying operating system running on the device; this can be achieved either by using a supported, documented mechanism or by exploiting another vulnerability that would provide an attacker with such access. Develop or have access to a platform-specific exploit. An attacker attempting to exploit this vulnerability across multiple affected platforms would need to research each one of those platforms and then develop a platform-specific exploit. Although the research process could be reused across different platforms, an exploit developed for a given hardware platform is unlikely to work on a different hardware platform.", }, { lang: "es", value: "Una vulnerabilidad en la lógica que maneja el control de acceso de uno de los componentes de hardware en la implementación Secure Boot de propiedad de Cisco, podría permitir que un atacante local autenticado escriba una imagen de firmware modificada en el componente. Esta vulnerabilidad afecta a varios productos de Cisco que admiten la funcionalidad de Secure Boot basada en hardware. La vulnerabilidad se genera por una comprobación incorrecta en el área de código que administra las actualizaciones en las instalaciones de Field Programmable Gate Array (FPGA) parte de la implementación del hardware Secure Boot. Un atacante con privilegios elevados y acceso al sistema operativo subyacente que se ejecuta en el dispositivo afectado podría explotar esta vulnerabilidad al escribir una imagen de firmware modificada en el FPGA. Una explotación exitosa podría hacer que el dispositivo se vuelva inutilizable (y requiera un reemplazo de hardware) o permitir la manipulación del proceso de comprobación de Secure Boot, que en algunas circunstancias puede permitir al atacante instalar y arrancar una imagen de software malicioso. Un atacante deberá cumplir todas las condiciones siguientes para intentar explotar esta vulnerabilidad: Tener acceso administrativo privilegiado al dispositivo. Poder acceder al sistema operativo subyacente que se ejecuta en el dispositivo; Esto se puede lograr mediante el uso de un mecanismo documentado de soporte o mediante la explotación de otra vulnerabilidad que proporcionaría a un atacante con dicho acceso. Desarrollar o tener acceso a un exploit específico de la plataforma. Un atacante que busque explotar esta vulnerabilidad en múltiples plataformas afectadas necesitará investigar cada una de esas plataformas y después desarrollar una vulnerabilidad específica de la plataforma. Si bien el proceso de investigación se podría realizar en diferentes plataformas, es poco probable que una vulnerabilidad desarrollada para una plataforma de hardware determinada opere en una plataforma de hardware diferente.", }, ], id: "CVE-2019-1649", lastModified: "2024-11-21T04:37:00.627", metrics: { cvssMetricV2: [ { acInsufInfo: false, baseSeverity: "HIGH", cvssData: { accessComplexity: "LOW", accessVector: "LOCAL", authentication: "NONE", availabilityImpact: "COMPLETE", baseScore: 7.2, confidentialityImpact: "COMPLETE", integrityImpact: "COMPLETE", vectorString: "AV:L/AC:L/Au:N/C:C/I:C/A:C", version: "2.0", }, exploitabilityScore: 3.9, impactScore: 10, obtainAllPrivilege: false, obtainOtherPrivilege: false, obtainUserPrivilege: false, source: "nvd@nist.gov", type: "Primary", userInteractionRequired: false, }, ], cvssMetricV30: [ { cvssData: { attackComplexity: "LOW", attackVector: "LOCAL", availabilityImpact: "HIGH", baseScore: 6.7, baseSeverity: "MEDIUM", confidentialityImpact: "HIGH", integrityImpact: "HIGH", privilegesRequired: "HIGH", scope: "UNCHANGED", userInteraction: "NONE", vectorString: "CVSS:3.0/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H", version: "3.0", }, exploitabilityScore: 0.8, impactScore: 5.9, source: "psirt@cisco.com", type: "Secondary", }, ], cvssMetricV31: [ { cvssData: { attackComplexity: "LOW", attackVector: "LOCAL", availabilityImpact: "HIGH", baseScore: 6.7, baseSeverity: "MEDIUM", confidentialityImpact: "HIGH", integrityImpact: "HIGH", privilegesRequired: "HIGH", scope: "UNCHANGED", userInteraction: "NONE", vectorString: "CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H", version: "3.1", }, exploitabilityScore: 0.8, impactScore: 5.9, source: "nvd@nist.gov", type: "Primary", }, ], }, published: "2019-05-13T19:29:01.520", references: [ { source: "psirt@cisco.com", tags: [ "Third Party Advisory", "VDB Entry", ], url: "http://www.securityfocus.com/bid/108350", }, { source: "psirt@cisco.com", tags: [ "Vendor Advisory", ], url: "https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190513-secureboot", }, { source: "psirt@cisco.com", tags: [ "Third Party Advisory", "US Government Resource", ], url: "https://www.kb.cert.org/vuls/id/400865", }, { source: "psirt@cisco.com", tags: [ "Third Party Advisory", "US Government Resource", ], url: "https://www.us-cert.gov/ics/advisories/icsa-20-072-03", }, { source: "af854a3a-2127-422b-91ae-364da2661108", tags: [ "Third Party Advisory", "VDB Entry", ], url: "http://www.securityfocus.com/bid/108350", }, { source: "af854a3a-2127-422b-91ae-364da2661108", tags: [ "Vendor Advisory", ], url: "https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190513-secureboot", }, { source: "af854a3a-2127-422b-91ae-364da2661108", tags: [ "Third Party Advisory", "US Government Resource", ], url: "https://www.kb.cert.org/vuls/id/400865", }, { source: "af854a3a-2127-422b-91ae-364da2661108", tags: [ "Third Party Advisory", "US Government Resource", ], url: "https://www.us-cert.gov/ics/advisories/icsa-20-072-03", }, ], sourceIdentifier: "psirt@cisco.com", vulnStatus: "Modified", weaknesses: [ { description: [ { lang: "en", value: "CWE-284", }, ], source: "psirt@cisco.com", type: "Secondary", }, { description: [ { lang: "en", value: "CWE-667", }, ], source: "nvd@nist.gov", type: "Primary", }, ], }
