CVE-2020-37065
Published: 03 February 2026
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.
