VAR-201905-0590
Vulnerability from variot - Updated: 2023-12-18 11:14A vulnerability in the system shell for Cisco Nexus 9000 Series Fabric Switches in Application Centric Infrastructure (ACI) mode could allow an authenticated, local attacker to use symbolic links to overwrite system files. These system files may be sensitive and should not be overwritable by non-root users. The attacker would need valid device credentials. The vulnerability is due to incorrect symbolic link verification of directory paths when they are used in the system shell. An attacker could exploit this vulnerability by authenticating to the device and providing crafted user input to specific symbolic link CLI commands. Successful exploitation could allow the attacker to overwrite system files that should be restricted. This vulnerability has been fixed in software version 14.1(1i). Cisco Nexus 9000 Series Fabric Switch Contains a path traversal vulnerability.Information may be tampered with. This may aid in further attacks. This issue is tracked by Cisco Bug ID CSCvo80695. The vulnerability stems from a network system or product that fails to properly filter resources or special elements in file paths. An attacker could exploit this vulnerability to access locations outside of restricted directories
