CVE-2025-4740Public exploit

Local code execution via untrusted pickle load

Published May 16, 2025 · Updated May 16, 2025

Deserialization in BeamCtrl Airiana 11.0 and earlier allows local users to execute arbitrary code through a crafted data file. The coef script passes coeficients.dat directly to Python's pickle.load(), so attacker-controlled pickle opcodes invoke arbitrary commands during loading. Exploitation requires write access to that local file and execution of the script; resulting commands inherit the script's privileges.
