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 10th 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 map to SI-16 (Memory Protection) and SI-2 (Flaw Remediation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

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.

MITRE ATT&CK Enterprise TechniquesAI

T1068 Exploitation for Privilege Escalation Privilege Escalation
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
Why these techniques?

Local buffer overflow enabling arbitrary code execution with no privileges required maps directly to exploitation for privilege escalation or code execution on the local system.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Requires timely identification, reporting, and patching of the buffer overflow flaw in RM Downloader to eliminate the vulnerability.

prevent

Implements memory safeguards like DEP and ASLR to protect against arbitrary code execution via buffer overflows, even against egg hunter bypass techniques.

prevent

Restricts user installation of unapproved software like vulnerable RM Downloader, preventing deployment of exploitable applications.

prevents

Secure coding directly requires bounds-checked memory operations, addressing the root cause of CWE-120.

detects

Security testing in development and acceptance can detect buffer overflows through fuzzing and static analysis, though it does not prevent them at the source.

prevents

Secure development life cycle mandates processes that can include input validation and bounds checking to prevent buffer overflows.

prevents

Application security requirements can specify input-size validation and safe buffer handling to mitigate classic buffer overflows.

prevents

Secure system architecture and engineering principles promote defensive coding patterns that reduce the likelihood of unchecked buffer copies.
