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 · unedited
A CWE-345: Insufficient Verification of Data Authenticity vulnerability exists in the Data Server that could cause access to delete files in the IGSS project report directory, this could lead to loss of data when an attacker sends specific crafted messages to the Data Server TCP port. Affected Products: IGSS Data Server(IGSSdataServer.exe)(V16.0.0.23040 and prior), IGSS Dashboard(DashBoard.exe)(V16.0.0.23040 and prior), Custom Reports(RMS16.dll)(V16.0.0.23040 and prior).

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.
