CVE-2020-36967: Zortam Mp3 Media Studio Buffer Overflow Leading to Remote Code Execution (SEH)

Overview

Zortam Mp3 Media Studio 27.60 is affected by a buffer overflow in the library creation file selection process. According to the CVE record and the NVD entry, a crafted text file can be used to overwrite a structured exception handler (SEH) and execute arbitrary commands.

Impact

The CVSS 3.1 vector supplied by VulnCheck describes a network-reachable attack with low complexity, no privileges required and high impact on confidentiality, integrity and availability.
The reported base score is 9.8 (critical) under CVSS 3.1 and 8.4 under CVSS 4.0.
The weakness is classified as CWE-121, stack-based buffer overflow.
Successful exploitation would allow code to run on the affected system with the rights of the application, according to the description. The exact privilege level is unknown.

Affected products and versions

The only affected version named in the record is Zortam Mp3 Media Studio 27.60.
The structured affected-product list in the record is empty, so the full range of affected versions is unknown.

Exploitation status

The CVE is not listed in CISA KEV in the record. No confirmed active exploitation appears in the sources consulted. The record includes a reference to an Exploit-DB entry, but this analysis does not assess its content and does not treat its presence as evidence of exploitation in the wild.

Remediation and mitigation

Identify every installation of Zortam Mp3 Media Studio, including portable copies, and record the installed version.
Check the vendor download page for newer builds and apply any update that the vendor provides. No fixed version is identified in the available sources.
If no update is available, consider removing or replacing the application on systems where it is not essential.
Restrict the processing of text files from untrusted sources and apply the principle of least privilege to the user accounts that run the software.
Consider application control or endpoint policies that limit what the media application can launch.

Detection guidance

Monitor for unexpected crashes of the application, which can indicate memory corruption attempts.
Review logs and endpoint telemetry for the media application starting unusual child processes or making unexpected network connections.
Track file-access events involving text files received from external sources and handled by the software.

Limitations of the available information

The record contains no fixed version, no structured affected-version data and no vendor advisory from Zortam.
EPSS and SSVC data are not available in the record.
The record title is empty; the title in this analysis is derived from the description.
The record status is Deferred, and the delivery method and required user interaction beyond the CVSS vector are not described.
The absence of a fix in the record does not mean that no fix exists.
