Summary

CVE-2020-37008 is a high-severity Authorization Bypass Through User-Controlled Key (CWE-639) vulnerability in Elektraweb (inferred from references). Its CVSS base score is 8.7 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 36.2th 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 AC-3 (Access Enforcement) and SI-10 (Information Input Validation).

Deeper analysis

CVE-2020-37008 is an authentication bypass vulnerability (CWE-639) affecting EasyPMS version 1.0.0. The flaw enables unprivileged users to manipulate SQL queries via JSON requests, allowing access to admin user information. It arises from weak input validation, where attackers inject single quotes into ID parameters to bypass proper token authentication and modify admin user passwords.

The vulnerability can be exploited remotely over the network (AV:N) by attackers requiring no privileges (PR:N), low attack complexity (AC:L), and no user interaction (UI:N). Exploitation yields high confidentiality impact through admin data disclosure and enables password changes, consistent with its CVSS v3.1 base score of 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).

Advisories from VulnCheck detail the issue, while proof-of-concept exploits are publicly available on Exploit-DB (ID 48858). The vendor site, Elektraweb, is referenced in connection with the software. No specific patches or mitigation steps are outlined in the provided details.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly mitigates weak input validation by requiring validation of JSON request inputs like ID parameters to block SQL injection with single quotes.

prevent

Enforces approved authorizations to prevent unprivileged users from accessing admin information or modifying passwords via bypassed mechanisms.

prevent

Strengthens management and protection of authenticators like tokens to reduce authentication bypass risks in API requests.
