CVE-2020-37053 Overview
Navigate CMS 2.8.7 contains an authenticated SQL injection vulnerability that allows attackers to leak database information by manipulating the sidx parameter in comments. Attackers can exploit the vulnerability to extract user activation keys by using time-based blind SQL injection techniques, potentially enabling password reset for administrative accounts.
Critical Impact
Authenticated attackers can extract sensitive database information including user activation keys, potentially leading to administrative account compromise through password reset functionality.

Technical Details for CVE-2020-37053
Vulnerability Analysis
This SQL injection vulnerability (CWE-89) exists in Navigate CMS version 2.8.7 where the sidx parameter used in comments functionality fails to properly sanitize user-supplied input before incorporating it into SQL queries. The vulnerability requires authentication, meaning an attacker must have valid credentials to the CMS before exploitation is possible.
The time-based blind SQL injection technique allows attackers to infer database contents by observing response time differences. By crafting malicious SQL statements that conditionally introduce delays, attackers can systematically extract data character by character without receiving direct query results in the response.
Root Cause
The root cause of this vulnerability is improper input validation and lack of parameterized queries in the comments handling functionality. The sidx parameter, which likely controls sorting or indexing of comments, is directly concatenated into SQL statements without proper sanitization or the use of prepared statements. This allows attackers to inject arbitrary SQL syntax that gets executed against the underlying database.
Attack Vector
The attack is network-based and requires low privileges (authenticated user account). An authenticated attacker can manipulate the sidx parameter in HTTP requests to the comments functionality, injecting SQL payloads designed to extract sensitive information. The time-based blind technique involves injecting conditional statements with time delays (such as SLEEP() or BENCHMARK() functions in MySQL) to determine true/false conditions about database contents.
The primary target of this attack appears to be user activation keys stored in the database. By extracting these keys, an attacker could potentially initiate password reset procedures for administrative accounts, leading to complete compromise of the CMS installation.
Detection Methods for CVE-2020-37053
Indicators of Compromise
- Unusual or malformed values in the sidx parameter within HTTP requests to Navigate CMS
- Database queries with abnormally long execution times indicating time-based injection attempts
- Repeated requests to comments-related endpoints with varying parameter values suggesting automated extraction
- SQL syntax characters (single quotes, semicolons, UNION, SELECT, SLEEP) appearing in request parameters
Detection Strategies
- Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in the sidx parameter
- Monitor application logs for requests containing SQL keywords or time-delay functions
- Deploy database activity monitoring to identify queries with unusual timing patterns or malformed syntax
- Enable detailed logging on Navigate CMS to capture all parameter values in requests
Monitoring Recommendations
- Set up alerting for database query execution times exceeding normal thresholds
- Monitor for multiple sequential requests from the same source targeting comments functionality
- Track failed authentication attempts followed by exploitation attempts against authenticated endpoints
- Review access logs for patterns consistent with automated SQL injection tools
How to Mitigate CVE-2020-37053
Immediate Actions Required
- Restrict access to Navigate CMS administrative functions to trusted IP addresses only
- Implement additional authentication controls for sensitive CMS operations
- Deploy a Web Application Firewall with SQL injection detection rules
- Audit all user accounts and disable any unnecessary authenticated access
Patch Information
Consult the NavigateCMS Official Website and SourceForge Project Page for the latest security updates and patched versions. The VulnCheck Advisory for NavigateCMS provides additional technical details about this vulnerability.
Workarounds
- Implement input validation at the web server or reverse proxy level to filter the sidx parameter
- Use a WAF rule to block requests containing SQL injection payloads in query parameters
- Consider disabling comments functionality if not required for business operations
- Restrict database user privileges for the Navigate CMS application to minimum required permissions
# Example WAF rule concept for ModSecurity
# Block SQL injection attempts in sidx parameter
SecRule ARGS:sidx "@rx (?i)(union|select|sleep|benchmark|waitfor|delay)" \
"id:100001,phase:2,deny,status:403,msg:'Potential SQL Injection in sidx parameter'"
