CVE-2020-10622

Arbitrary file creation via improper input validation

Published May 4, 2020 · Updated Aug 4, 2024

Improper input validation in LAquis SCADA 4.3.1 and earlier allows local users to create arbitrary files after user interaction. CISA identifies the flaw as improper input validation but does not disclose the affected parser, input field, or file-operation path. Exploitation requires high privileges and a separate user’s interaction, and resulting writes can alter files available to the application.
