Vulnerability from variot
A vulnerability in the Image Signature Verification feature of Cisco NX-OS Software could allow an authenticated, local attacker with administrator-level credentials to install a malicious software image on an affected device. The vulnerability exists because software digital signatures are not properly verified during CLI command execution. An attacker could exploit this vulnerability to install an unsigned software image on an affected device. Cisco NX-OS The software contains a vulnerability related to digital signature verification.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Successfully exploiting these issues may allow an attacker to perform unauthorized actions. This may lead to other attacks. This issue is being tracked by Cisco Bug IDs CSCvj14093, CSCvj14106, CSCvj14182, CSCvk53125, CSCvk53227, CSCvk53256. Cisco NX-OS Software is a data center-level operating system software used by a set of switches of Cisco. The vulnerability stems from a network system or product not adequately verifying the origin or authenticity of data. Attackers can use forged data to attack. The following products and versions are affected: Cisco Nexus 3000 Series Switches; Nexus 3600 Platform Switches; Nexus 9000 Series Switches in standalone NX-OS mode; Nexus 9500 R-Series Switching Platform

"data": "A vulnerability in the Image Signature Verification feature of Cisco NX-OS Software could allow an authenticated, local attacker with administrator-level credentials to install a malicious software image on an affected device. The vulnerability exists because software digital signatures are not properly verified during CLI command execution. An attacker could exploit this vulnerability to install an unsigned software image on an affected device. Cisco NX-OS The software contains a vulnerability related to digital signature verification.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. \nSuccessfully exploiting these issues may allow an attacker to perform unauthorized actions. This may lead to other attacks. \nThis issue is being tracked by Cisco Bug IDs CSCvj14093, CSCvj14106, CSCvj14182, CSCvk53125, CSCvk53227, CSCvk53256. Cisco NX-OS Software is a data center-level operating system software used by a set of switches of Cisco. The vulnerability stems from a network system or product not adequately verifying the origin or authenticity of data. Attackers can use forged data to attack. The following products and versions are affected: Cisco Nexus 3000 Series Switches; Nexus 3600 Platform Switches; Nexus 9000 Series Switches in standalone NX-OS mode; Nexus 9500 R-Series Switching Platform",
