Summary

CVE-2020-37053 is a high-severity SQL Injection (CWE-89) vulnerability in Naviwebs Navigate Cms. Its CVSS base score is 7.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 3.6th 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-2 (Flaw Remediation).

Deeper analysis

Navigate CMS version 2.8.7 is affected by CVE-2020-37053, an authenticated SQL injection vulnerability (CWE-89) in the 'sidx' parameter within the comments functionality. This flaw allows attackers to manipulate the parameter to leak database information through time-based blind SQL injection techniques. The vulnerability has a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N), indicating high confidentiality impact with low privileges required.

Authenticated users with low privileges (PR:L) can exploit this vulnerability remotely over the network with low complexity and no user interaction. Successful exploitation enables extraction of sensitive database contents, such as user activation keys, which could facilitate password resets for administrative accounts, potentially leading to unauthorized account takeover.

Advisories and references, including those from VulnCheck and an Exploit-DB entry (exploit 48545), detail the issue; security practitioners should consult these for patch information or upgrade guidance from the Navigate CMS project on SourceForge or its official site. No specific mitigation steps are outlined in the core CVE details.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1552 Unsecured Credentials Credential Access
Adversaries may search compromised systems to find and obtain insecurely stored credentials.
Why these techniques?

SQL injection in public-facing CMS directly enables T1190; DB data extraction (activation keys) enables T1552 for account takeover.

prevent

Directly requires validation of inputs such as the 'sidx' parameter to block SQL injection payloads before they reach the database.

prevent

Mandates timely remediation of known flaws such as the authenticated SQL injection in Navigate CMS 2.8.7 via patching or upgrade.

prevent

Restricts the actions available to low-privilege authenticated accounts, limiting the ability to reach or exploit the vulnerable comments functionality.
