CVE-2018-25418: SQL Injection in AiOPMSD Final 1.0.0 – Unauthenticated Remote Code Execution Risk

Technical summary

This is a classic SQL injection vulnerability (CWE-89) affecting AiOPMSD Final 1.0.0. The year parameter in year.php fails to properly sanitize or parameterize user input before incorporating it into SQL queries. An attacker can inject SQL metacharacters and commands to break out of the intended query context and execute arbitrary SQL statements. The attack vector is straightforward: GET requests to year.php with crafted payloads in the year parameter bypass input validation and reach the database layer directly. The vulnerability permits information disclosure attacks targeting the database schema, credentials, and system metadata.

Business impact

Successful exploitation could expose your organization's database credentials, usernames, and structural information that attackers use for reconnaissance and further attacks. This information disclosure may lead to unauthorized data access, compliance violations if personal or regulated data is exposed, and reputational damage. Because exploitation requires no authentication or user interaction, the exposure window is immediate and continuous until the application is patched or taken offline.

Affected systems

AiOPMSD Final version 1.0.0 is confirmed vulnerable. Organizations running this specific version—particularly in production environments—face direct risk. The vulnerability affects any deployment of this software accessible over the network. No other versions or products are specified in the published data, so verify your inventory against version 1.0.0 specifically.

Exploitability

This vulnerability has a high exploitability profile. The attack requires no authentication, no special privileges, and no user interaction. Network access is sufficient. The exploit technique—SQL injection via URL parameters—is well-understood and easily weaponized. Automated scanning tools can detect the vulnerable parameter and attempt injection payloads with minimal effort. The fact that the vulnerability is not yet listed on the CISA Known Exploited Vulnerabilities (KEV) catalog does not diminish the technical ease of exploitation; it reflects publication recency rather than difficulty.

Remediation

Upgrade AiOPMSD Final to a patched version released after this vulnerability's publication date of May 30, 2026. Contact your vendor for patched releases and timelines. As an interim measure, isolate the affected application from untrusted networks, disable or restrict access to year.php if operationally feasible, and implement Web Application Firewall (WAF) rules to block SQL injection patterns in the year parameter. Monitor database query logs for suspicious SQL syntax or error messages that may indicate exploitation attempts.

Patch guidance

Check the AiOPMSD vendor's security advisories and release notes for patches addressing CVE-2018-25418. Patches should be applied to all instances of version 1.0.0 in your environment. Before deploying patches to production, test them in a staging environment to confirm compatibility with your configurations and downstream systems. Verify patch application by confirming the installed version and re-testing the vulnerable year.php parameter with safe payloads to confirm input sanitization is in place.

Detection guidance

Monitor for GET requests to year.php containing SQL metacharacters (single quotes, double quotes, dashes, semicolons, keywords like 'UNION', 'SELECT', 'OR', 'AND') in the year parameter. Database activity logs may show unusual queries, errors related to malformed SQL, or unexpected data retrieval patterns. Web application firewall logs should flag attempts to inject SQL syntax. Consider deploying SQL injection detection signatures and correlating web server logs with database query logs to identify exploitation attempts.

Why prioritize this

This vulnerability scores 8.2 (HIGH) under CVSS 3.1 and poses significant risk due to the combination of unauthenticated access, high confidentiality impact (database credential and schema exposure), and trivial exploit complexity. The lack of authentication requirement and straightforward network attack vector make this a priority remediation target. Organizations should treat this as urgent if they operate AiOPMSD Final 1.0.0 in any network-accessible location.

Risk score, explained

The CVSS 3.1 score of 8.2 reflects: (1) Network attack vector—exploitable remotely with no special network positioning; (2) Low attack complexity—no special conditions or authentication required; (3) No privileges required—unauthenticated attackers can exploit; (4) No user interaction—attacks succeed autonomously; (5) High confidentiality impact—sensitive database information is exposed; (6) Low integrity impact—the vulnerability primarily enables data exfiltration rather than modification; (7) No availability impact—the application does not crash or become unavailable. The high score appropriately emphasizes the information disclosure risk and ease of exploitation.
