CVE-2018-25413: AiOPMSD SQL Injection Vulnerability – Unauthenticated Database Access

Technical summary

CVE-2018-25413 is an unauthenticated SQL injection vulnerability in the 'q' parameter of search.php in AiOPMSD Final 1.0.0. The application fails to properly sanitize or parameterize user input before incorporating it into SQL queries, allowing attackers to inject arbitrary SQL commands via GET requests. The vulnerability maps to CWE-89 (SQL Injection) and carries a CVSS 3.1 score of 8.2 (HIGH severity), reflecting high confidentiality impact with low integrity impact and no availability impact. The network-accessible attack vector combined with low complexity creates significant risk for systems running this version.

Business impact

Exploitation of this vulnerability could result in unauthorized access to sensitive database contents, including user credentials, system metadata, and potentially confidential business data stored within the application. The combination of unauthenticated access and high confidentiality impact means attackers can systematically extract information without leaving obvious audit trails. Organizations running AiOPMSD Final 1.0.0 face reputational risk, potential regulatory violations (depending on data classification and jurisdiction), and exposure of administrative credentials that could facilitate lateral movement or system compromise.

Affected systems

AiOPMSD Final version 1.0.0 is the confirmed affected version. Organizations should inventory all deployments of this application, including development, staging, and production environments. Systems exposed directly to untrusted networks or the internet face the highest risk. Internal deployments accessible only to authenticated users face lower attack surface, though insider threats remain relevant.

Exploitability

This vulnerability is highly exploitable. It requires no authentication, can be triggered via simple HTTP GET requests with crafted parameters, and requires no user interaction or special browser capabilities. An attacker with network access to search.php can execute reconnaissance-level attacks immediately using basic fuzzing or publicly available SQL injection payloads. The low attack complexity means minimal technical skill is required to attempt exploitation. As of the last assessment, this vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog, though the straightforward nature of SQL injection attacks means functional exploits are likely to emerge or already exist in private use.

Remediation

Immediate action required: upgrade AiOPMSD Final to a patched version released by the vendor after the vulnerability discovery. Verify the specific patched version in the official vendor advisory. As interim measures before patching is possible, consider restricting network access to search.php to trusted IP ranges, implementing Web Application Firewall rules to block common SQL injection patterns in the 'q' parameter, and enabling SQL query logging to detect suspicious activity. Input validation at the application layer should enforce strict whitelisting on search parameters.

Patch guidance

Contact the AiOPMSD Final vendor for availability of security updates addressing CVE-2018-25413. Patched versions should be verified against official vendor security advisories before deployment. Test patches in a non-production environment to confirm functionality and compatibility. Given the high severity and ease of exploitation, prioritize patching production systems within your standard change management window—ideally within 1-2 weeks of patch availability. Document the vulnerability scan and patching timeline for compliance records.

Detection guidance

Monitor web server logs for unusual patterns in search.php requests, including: multiple failed query attempts, requests with SQL keywords or syntax characters (SELECT, UNION, OR, --, ;, etc.) in the 'q' parameter, and requests from unexpected geographic regions or user agents. Implement WAF rules to flag or block requests containing common SQL injection signatures. Query database audit logs for unexpected system commands or schema enumeration queries. Conduct periodic database access reviews to identify any unauthorized query activity. Log all search operations and correlate with application error logs to identify injection attempts.

Why prioritize this

This vulnerability warrants HIGH priority remediation due to the combination of (1) unauthenticated network-accessible attack surface, (2) high confidentiality impact with direct access to database contents, (3) low attack complexity requiring minimal sophistication, (4) potential for rapid exploitation at scale, and (5) absence of authentication barriers. Organizations should treat this equivalent to a critical patch despite not being listed in the KEV catalog, given the straightforward nature of SQL injection attacks and the sensitivity of typical database contents.

Risk score, explained

The CVSS 3.1 score of 8.2 (HIGH) reflects the following: Attack Vector (Network) indicates internet-exploitable scope; Attack Complexity (Low) means standard SQL injection techniques apply; Privileges Required (None) and User Interaction (None) eliminate barriers to exploitation; Confidentiality Impact (High) shows full database access potential; Integrity Impact (Low) indicates limited write/modification capability; Availability Impact (None) suggests the injection does not degrade system uptime. The high confidentiality impact combined with network accessibility and no authentication requirement justifies prioritization ahead of many 'Critical' vulnerabilities with lower real-world exploitability.
