VAR-201905-0532
Vulnerability from variot - Updated: 2023-12-18 12:00A 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 patch on an affected device. The vulnerability is due to improper verification of digital signatures for patch images. An attacker could exploit this vulnerability by crafting an unsigned software patch to bypass signature checks and loading it on an affected device. A successful exploit could allow the attacker to boot a malicious software patch image. 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. Multiple Cisco Products prone to an local security-bypass vulnerability. An attacker may exploit this issue to bypass certain security restrictions and perform unauthorized actions. This may lead to further attacks. This issue is being tracked by Cisco Bug IDs CSCvi42264 and CSCvj12239. 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 MDS 9700 Series Multilayer Directors; Nexus 7000 Series Switches; Nexus 7700 Series Switches; UCS 6200 Series Fabric Interconnects; UCS 6300 Series Fabric Interconnects

"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 patch on an affected device. The vulnerability is due to improper verification of digital signatures for patch images. An attacker could exploit this vulnerability by crafting an unsigned software patch to bypass signature checks and loading it on an affected device. A successful exploit could allow the attacker to boot a malicious software patch image. 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. Multiple Cisco Products prone to an local security-bypass vulnerability. \nAn attacker may exploit this issue to bypass certain security restrictions and perform unauthorized actions. This may lead to further attacks. \nThis issue is being tracked by Cisco Bug IDs CSCvi42264 and CSCvj12239. 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 MDS 9700 Series Multilayer Directors; Nexus 7000 Series Switches; Nexus 7700 Series Switches; UCS 6200 Series Fabric Interconnects; UCS 6300 Series Fabric Interconnects",
