    A vulnerability in the logging feature of Cisco NX-OS Software for Cisco Nexus 3000 Series Switches, Cisco Nexus 9000 Series Switches in standalone NX-OS mode, Cisco UCS 6400 Fabric Interconnects, Cisco UCS 6500 Series Fabric Interconnects, and Cisco UCS 9108 100G Fabric Interconnects could allow an authenticated, local attacker access to sensitive information. This vulnerability is due to improper logging of sensitive information. An attacker could exploit this vulnerability by accessing log files on the file system where they are stored. A successful exploit could allow the attacker to access sensitive information, such as stored credentials. Note: To access the log files on Cisco Nexus devices that are affected by this vulnerability, an attacker must have access to the file system of the underlying operating system. For more information about access requirements, see the Cisco Nexus 9000 Series Switches Programming Guides ["https://www.cisco.com/c/en/us/support/switches/nexus-9000-series-switches/products-programming-reference-guides-list.html"]. To access the log files on Cisco UCS Fabric Interconnect devices, an administrator of UCS Manager must generate and download a tech support file, which includes the system log files. The system log files are not directly accessible from the CLI or the Cisco UCS Manager UI. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. This advisory is part of the August 2025 Cisco FXOS and NX-OS Software Security Advisory Bundled Publication. For a complete list of the advisories and links to them, see Cisco Event Response: August 2025 Semiannual Cisco FXOS and NX-OS Software Security Advisory Bundled Publication ["https://sec.cloudapps.cisco.com/security/center/viewErp.x?alertId=ERP-75667"].
