CVE-2023-31172

Instruction execution via incompletely filtered input

Published Aug 31, 2023 · Updated Sep 27, 2024

Incomplete input filtering in SEL-5030 acSELerator QuickSet Software 7.1.3.0 and earlier allows attackers to embed executable instructions. SEL and Nozomi have not published the affected parser, input format, or special elements that pass through filtering. Execution requires an authorized device operator to process the attacker-supplied content, and the published impact is limited to instruction execution in that operator-driven workflow.
