CVE-2020-14496
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedSuccessful exploitation of this vulnerability for multiple Mitsubishi Electric Factory Automation Engineering Software Products of various versions could allow an attacker to escalate privilege and execute malicious programs, which could cause a denial-of-service condition, and allow information to be disclosed, tampered with, and/or destroyed.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
