CVE-2023-7206

Code execution via CSP parsing stack overflow

Published Jan 15, 2024 · Updated Nov 13, 2024

Stack-based buffer overflow in Horner Automation Cscape 9.90 SP10 and earlier allows local users to execute code via a malicious CSP file. The CSP project-file parser does not properly validate attacker-controlled data, causing a stack buffer overflow while processing the file. Exploitation requires a user to open the crafted file, after which code runs in the context of the Cscape process.
