VAR-201905-0249
Vulnerability from variot - Updated: 2023-12-18 12:00A vulnerability in the Bash shell implementation for Cisco NX-OS Software could allow an authenticated, local attacker to bypass the limited command set of the restricted Guest Shell and execute commands at the privilege level of a network-admin user outside of the Guest Shell. The attacker must authenticate with valid administrator device credentials. The vulnerability is due to the incorrect implementation of a CLI command that allows a Bash command to be incorrectly invoked on the Guest Shell CLI. An attacker could exploit this vulnerability by authenticating to the device and entering a crafted command at the Guest Shell prompt. A successful exploit could allow the attacker to issue commands that should be restricted by a Guest Shell account. Cisco NX-OS The software contains vulnerabilities related to authorization, permissions, and access control.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Cisco NX-OS System Software is prone to a local security-bypass vulnerability. This may aid in further attacks. This issue is being tracked by Cisco Bug IDs CSCvh76090, CSCvj01472, CSCvj01497 . The implementation of the Bash shell in Cisco NX-OS Software is vulnerable to permission and access control issues. The vulnerability stems from the lack of effective permissions and access control measures in network systems or products. The following products and versions are affected: Cisco Nexus 3000 Series Switches; Nexus 3500 Platform Switches; Nexus 3600 Platform Switches; Nexus 7000 Series Switches; Nexus 7700 Series Switches; Nexus 9000 Series Switches in standalone NX-OS mode; Platform

"data": "A vulnerability in the Bash shell implementation for Cisco NX-OS Software could allow an authenticated, local attacker to bypass the limited command set of the restricted Guest Shell and execute commands at the privilege level of a network-admin user outside of the Guest Shell. The attacker must authenticate with valid administrator device credentials. The vulnerability is due to the incorrect implementation of a CLI command that allows a Bash command to be incorrectly invoked on the Guest Shell CLI. An attacker could exploit this vulnerability by authenticating to the device and entering a crafted command at the Guest Shell prompt. A successful exploit could allow the attacker to issue commands that should be restricted by a Guest Shell account. Cisco NX-OS The software contains vulnerabilities related to authorization, permissions, and access control.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Cisco NX-OS System Software is prone to a local security-bypass vulnerability. This may aid in further attacks. \nThis issue is being tracked by Cisco Bug IDs CSCvh76090, CSCvj01472, CSCvj01497 . The implementation of the Bash shell in Cisco NX-OS Software is vulnerable to permission and access control issues. The vulnerability stems from the lack of effective permissions and access control measures in network systems or products. The following products and versions are affected: Cisco Nexus 3000 Series Switches; Nexus 3500 Platform Switches; Nexus 3600 Platform Switches; Nexus 7000 Series Switches; Nexus 7700 Series Switches; Nexus 9000 Series Switches in standalone NX-OS mode; Platform",
