CVE-2023-54328: Aimone Video Converter Buffer Overflow

CVE-2023-54328 Overview

CVE-2023-54328 is a buffer overflow vulnerability [CWE-120] in AimOne Video Converter version 2.04 Build 103. The flaw resides in the application's registration form, where supplying an oversized input of approximately 7000 bytes triggers a memory corruption condition that crashes the process. Attackers with local access can leverage the bug to cause a denial of service against the desktop application. The vulnerability affects an unmaintained consumer video conversion utility from Aimonesoft, with public exploit details published in Exploit-DB entry 51196.

Critical Impact
Local attackers can crash AimOne Video Converter 2.04 Build 103 by submitting a 7000-byte payload to the registration form, producing a denial of service and potentially undermining the registration mechanism.

Technical Details for CVE-2023-54328

Vulnerability Analysis

The vulnerability is a classic stack-based buffer overflow [CWE-120] in the registration dialog of AimOne Video Converter 2.04 Build 103. The application copies user-supplied input from the registration form into a fixed-size buffer without enforcing length validation. When the input exceeds the buffer capacity, adjacent stack memory is corrupted and the process terminates.

Public proof-of-concept material referenced in the Exploit-DB entry #51196 and the GitHub CVE Repository demonstrates that a 7000-byte payload reliably crashes the application. The VulnCheck Advisory for AimOne characterizes the issue as a buffer overflow in the registration form.

Root Cause

The registration form handler lacks bounds checking on the input field. The routine reads attacker-controlled data directly into a stack buffer using an unsafe copy operation. Because the buffer size is smaller than the maximum accepted input, oversized strings overwrite saved return addresses and structured exception handler records.

Attack Vector

Exploitation requires local interaction with the application's registration dialog. An attacker, or a user tricked into pasting a malicious string, supplies a long payload to the registration field. The application processes the input and crashes. The CVSS vector indicates a local attack path with no privileges or user interaction required beyond invoking the registration workflow, and impact is limited to availability.

No verified exploit code is reproduced here. See the references above for technical details and a reproducer.

Detection Methods for CVE-2023-54328

Indicators of Compromise

Unexpected crashes of AimOne Video Converter.exe accompanied by Windows Error Reporting (WER) entries referencing access violations in the registration dialog.
Application Event Log entries showing faulting module addresses within the AimOne process space immediately after a registration attempt.
Presence of unusually large strings (multi-kilobyte) submitted to the registration form, captured in user activity logs or screen recordings.

Detection Strategies

Monitor endpoint telemetry for repeated process termination events tied to the AimOne Video Converter executable.
Correlate user-mode crash dumps in %LOCALAPPDATA%\CrashDumps with the AimOne process to flag suspicious overflow attempts.
Alert on execution of legacy or end-of-life software such as AimOne Video Converter 2.04 across managed endpoints.

Monitoring Recommendations

Inventory endpoints running AimOne Video Converter using software asset management tooling and flag the affected build.
Track Windows Error Reporting telemetry centrally to surface clustered crashes that may indicate exploitation attempts.
Review historical EDR process telemetry for anomalous child processes spawned by the AimOne binary following crashes.

How to Mitigate CVE-2023-54328

Immediate Actions Required

Remove AimOne Video Converter 2.04 Build 103 from managed endpoints, as the product appears unmaintained per the Archived AimOne Website.
Restrict execution of the AimOne binary via application allowlisting until removal is complete.
Advise users not to enter data into the registration dialog and to avoid opening untrusted registration key files.

Patch Information

No vendor patch is available. The vendor website is archived and Aimonesoft does not appear to be actively maintaining the product. Organizations should treat the application as end-of-life and replace it with a supported video conversion tool. Refer to the VulnCheck Advisory for AimOne for the most current advisory status.

Workarounds

Uninstall the affected build and migrate users to an actively supported alternative.
Enforce application control policies (for example, Windows Defender Application Control or AppLocker) to block execution of the AimOne Video Converter executable.
Run the application in a restricted, non-privileged user context if removal is not immediately possible, limiting the blast radius of a crash.
Disable or hide the registration workflow through desktop policy where feasible to prevent users from triggering the vulnerable code path.
