TITLE

Cisco NX-OS Vulnerabilities related to digital signature verification in system software

Trust: 0.8

sources: JVNDB: JVNDB-2017-010551

DESCRIPTION

A vulnerability in Cisco NX-OS System Software could allow an authenticated, local attacker to bypass signature verification when loading a software patch. The vulnerability is due to insufficient NX-OS signature verification for software patches. An authenticated, local attacker could exploit this vulnerability to bypass signature verification and load a crafted, unsigned software patch on a targeted device. The attacker would need valid administrator credentials to perform this exploit. This vulnerability affects the following products running Cisco NX-OS System Software: Multilayer Director Switches, Nexus 7000 Series Switches, Nexus 7700 Series Switches, Unified Computing System Manager. Cisco Bug IDs: CSCvf16494, CSCvf23655. Vendors have confirmed this vulnerability Bug ID CSCvf16494 and CSCvf23655 It is released as.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Cisco MultilayerDirectorSwitches, etc. are products of Cisco. Cisco MultilayerDirectorSwitches is a switch product. UnifiedComputingSystemManager is a set of embedded device management software. Cisco NX-OS System Software is a set of software that runs on the switch. This may aid in further attacks
