Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Mandates timely identification, reporting, and remediation of flaws like the stack overflow in Torrent FLV Converter, including patching if available or removal otherwise.

CM-10 Software Usage Restrictions good match

prevent

Authorizes and restricts software usage to approved applications only, preventing execution of vulnerable third-party software such as Torrent FLV Converter.

SI-16 Memory Protection good match

prevent

Implements memory safeguards like DEP and ASLR that directly mitigate stack overflow exploits involving SEH overwrites on 32-bit Windows systems.

NVD Description

Torrent FLV Converter 1.51 Build 117 contains a stack overflow vulnerability that allows attackers to overwrite Structured Exception Handler (SEH) through a malicious registration code input. Attackers can craft a payload with specific offsets and partial SEH overwrite techniques to…

potentially execute arbitrary code on vulnerable Windows 32-bit systems.

Deeper analysisAI

CVE-2020-37181 is a stack overflow vulnerability in Torrent FLV Converter version 1.51 Build 117. The issue arises from a malicious registration code input that enables attackers to overwrite the Structured Exception Handler (SEH) using specific offsets and partial SEH overwrite techniques. It affects vulnerable 32-bit Windows systems and is classified under CWE-121 with a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

Remote attackers can exploit this vulnerability over the network without requiring user privileges or interaction. By crafting a suitable payload, they can achieve arbitrary code execution on the target system, compromising confidentiality, integrity, and availability to a high degree.
