CVE-2020-7494
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 · uneditedA CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability exists in EcoStruxure Operator Terminal Expert 3.1 Service Pack 1 and prior (formerly known as Vijeo XD) which could cause malicious code execution when opening the project file.
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.
dbcve analysis · moderate confidenceThis is a path traversal (CWE-22) vulnerability in EcoStruxure Operator Terminal Expert. When a user opens a maliciously crafted project file, the application fails to properly validate file paths, allowing the attacker to use '..' sequences to traverse directories and potentially execute arbitrary code on the targeted system.
