CVE-2023-52310Public exploitNetwork attack vector

Arbitrary command execution via unsanitized interval input

Published Jan 3, 2024 · Updated Apr 17, 2025

Command injection in PaddlePaddle before 2.6.0 allows attackers to execute arbitrary operating-system commands through crafted API input. The get_online_pass_interval method concatenates its days and hours arguments into echo commands passed to os.popen without first rejecting shell metacharacters. Exploitation requires an application or workflow to pass attacker-influenced values into either argument, after which commands run with the host process's privileges.
