Summary

CVE-2020-37065 is a high-severity Classic Buffer Overflow (CWE-120) vulnerability. Its CVSS base score is 8.4 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 24.6th 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 SI-10 (Information Input Validation) and SI-16 (Memory Protection).

Deeper analysis

CVE-2020-37065 is a buffer overflow vulnerability in StreamRipper32 version 2.6, specifically in the Station/Song Section. The flaw allows attackers to overwrite memory by manipulating the SongPattern input with a malicious payload exceeding 256 bytes, potentially leading to arbitrary code execution and full application compromise. It carries a CVSS score of 9.8 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) and maps to CWE-120.

Remote attackers can exploit this vulnerability over the network without authentication, privileges, or user interaction, using low-complexity methods. Successful exploitation enables high-impact effects on confidentiality, integrity, and availability, allowing arbitrary code execution on the targeted system running the vulnerable software.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1203 Exploitation for Client Execution Execution
Adversaries may exploit software vulnerabilities in client applications to execute code.
Why these techniques?

Buffer overflow enables unauthenticated remote arbitrary code execution on a network-accessible application (T1190) or client software (T1203).
