Vulnerability from cvelistv5 – Published: 2020-08-26 16:15 – Updated: 2024-11-13 18:13

Title

Cisco Data Center Network Manager Information Disclosure Vulnerability

Summary

A vulnerability in Cisco Data Center Network Manager (DCNM) Software could allow an authenticated, local attacker to obtain confidential information from an affected device. The vulnerability is due to insufficient protection of confidential information on an affected device. An attacker at any privilege level could exploit this vulnerability by accessing local filesystems and extracting sensitive information from them. A successful exploit could allow the attacker to view sensitive data, which they could use to elevate their privilege.

Severity

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
