Summary

CVE-2020-36967 is a high-severity Stack-based Buffer Overflow (CWE-121) vulnerability in Zortam Mp3 Media (inferred from references). Its CVSS base score is 8.4 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Client Execution (T1203); ranked at the 39.6th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 RA-5 (Vulnerability Monitoring and Scanning) and SI-16 (Memory Protection).

Deeper analysis

CVE-2020-36967 is a buffer overflow vulnerability (CWE-121) in Zortam Mp3 Media Studio version 27.60, specifically within the library creation file selection process. This flaw enables remote code execution when attackers craft a malicious text file containing shellcode that triggers a structured exception handler (SEH) overwrite. The vulnerability carries 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) and was published on 2026-01-28.

Remote attackers require no privileges or authentication to exploit this issue. By delivering a specially crafted text file through the library creation process, they can achieve arbitrary command execution on the target system, potentially compromising confidentiality, integrity, and availability.
