Summary

CVE-2020-36980 is a high-severity Unquoted Search Path or Element (CWE-428) vulnerability in Segurazo (inferred from references). Its CVSS base score is 8.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Path Interception by Unquoted Path (T1574.009); ranked at the 2.9th 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 CM-2 (Baseline Configuration) and CM-6 (Configuration Settings).

Deeper analysis

CVE-2020-36980 is an unquoted service path vulnerability in SAntivirus IC version 10.0.21.61. The issue affects the Windows service configuration of this antivirus software, where the service binary path lacks proper quoting, enabling potential exploitation by local attackers to execute arbitrary code through path traversal.

Local attackers with low privileges (PR:L) can exploit this vulnerability given local access (AV:L) and low complexity (AC:L), without requiring user interaction (UI:N). By injecting malicious files into directories traversed by the unquoted executable path, attackers achieve privilege escalation to system-level permissions, resulting in high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H), as reflected in the CVSS v3.1 base score of 7.8. The vulnerability maps to CWE-428 (Unquoted Search Path or Element).

MITRE ATT&CK Enterprise TechniquesAI

T1574.009 Path Interception by Unquoted Path Stealth
Adversaries may execute their own malicious payloads by hijacking vulnerable file path references.
T1068 Exploitation for Privilege Escalation Privilege Escalation
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
Why these techniques?

Unquoted service path directly enables path interception for local privilege escalation via malicious executable placement in the service binary path.
