CVE-2020-37036
Published: 30 January 2026
Summary
CVE-2020-37036 is a high-severity Classic Buffer Overflow (CWE-120) vulnerability in Informer (inferred from references). Its CVSS base score is 7.1 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 10.0th 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-16 (Memory Protection) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2020-37036 is a local buffer overflow vulnerability (CWE-120) affecting RM Downloader version 2.50.60, specifically in the 'Load' parameter. This flaw enables attackers to overwrite memory, leading to arbitrary code execution. The vulnerability carries a CVSS v3.1 base score of 8.4 (AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), highlighting its high impact on confidentiality, integrity, and availability in a local attack context.
A local attacker can exploit this vulnerability with low complexity and no privileges required, without needing user interaction. By crafting a malicious payload incorporating an egg hunter technique, the attacker can bypass memory protections and execute arbitrary commands, such as launching calc.exe.
