Executive Summary

CVE-2020-37013 is a local buffer overflow vulnerability in Audio Playback Recorder version 3.2.2, specifically affecting the "eject" and "registration" input parameters. Attackers can craft malicious payloads that overwrite the Structured Exception Handler (SEH) by pasting specially crafted input into the application's input fields. This allows execution of arbitrary code, such as running shellcode, when the overwritten SEH is triggered. [1, 4]

Detection Guidance

This vulnerability is a local buffer overflow in Audio Playback Recorder 3.2.2 triggered by pasting specially crafted input into the application's 'eject' and 'registration' input fields. Detection involves verifying if the vulnerable version (3.2.2) of Audio Playback Recorder is installed on the system. Since it is a local vulnerability requiring user interaction, network detection is not applicable. There are no specific commands provided to detect exploitation attempts. However, you can check the installed software version and monitor for unusual application crashes or behavior when using the 'eject' or 'registration' features. [1, 4]
