CVE-2018-25417: SQL Injection in AiOPMSD Final 1.0.0 – Unauthenticated Database Access

Technical summary

This is a classic SQL injection vulnerability (CWE-89) affecting AiOPMSD Final version 1.0.0. The application fails to sanitize or parameterize the 'quality' GET parameter before passing it to a SQL query. An unauthenticated network attacker can send specially crafted requests to quality.php that inject SQL syntax—such as UNION SELECT, OR conditions, or comment sequences—to bypass query logic and extract arbitrary data from the database. The vulnerability exists in a parameter that likely lacks input validation, type checking, or prepared statement usage.

Business impact

Successful exploitation enables unauthorized access to sensitive database contents, including user credentials, internal system identifiers, and database version information. This creates immediate risk of account takeover, privilege escalation, and further lateral movement within the application or infrastructure. Data exfiltration can trigger regulatory compliance violations (GDPR, HIPAA, PCI-DSS depending on data classification) and reputational damage. The unauthenticated nature of the attack means no insider access or stolen credentials are required—any internet-facing deployment is immediately at risk.

Affected systems

AiOPMSD Final version 1.0.0 is confirmed vulnerable. The quality.php endpoint and the quality GET parameter are the primary attack surface. Any deployment of this version, particularly internet-facing or accessible from untrusted networks, should be considered exposed. Organizations must inventory all instances of AiOPMSD Final 1.0.0 in their environment, including development, test, and production systems.

Exploitability

Exploitability is very high. The attack requires no authentication, no special privileges, and no user interaction. It can be executed via simple HTTP GET requests from any network-connected system. Automated scanning and exploitation tools can trivially identify and abuse this vulnerability at scale. The low attack complexity and high impact make this a critical priority for rapid remediation.

Remediation

Immediate actions: Take any internet-facing AiOPMSD Final 1.0.0 deployments offline or restrict network access to trusted sources only via firewall or network segmentation. Contact the AiOPMSD vendor to obtain a patched version or security advisory. Implement input validation and SQL injection protections at the application layer. Consider using parameterized queries (prepared statements) for all database operations. Audit database access logs for evidence of exploitation attempts or successful data extraction.

Patch guidance

Check the vendor's official advisory and support channels for a patched version of AiOPMSD that addresses this SQL injection flaw. Verify patch availability and compatibility with your deployed version before applying updates. If no patch is publicly available, maintain strict network controls and consider architectural changes such as deploying a Web Application Firewall (WAF) with SQL injection detection rules while awaiting an official fix.

Detection guidance

Monitor quality.php endpoints for GET requests containing suspicious SQL syntax patterns such as single quotes, SQL keywords (UNION, SELECT, OR, AND, COMMENT sequences like -- or /*), and URL-encoded variants (%27, %2D%2D). Implement query logging on the backend database to capture and alert on unusual SQL patterns. Review web application firewall (WAF) logs for SQL injection signature matches. Search historical logs for requests to quality.php with special characters or SQL keywords to identify potential past exploitation.

Why prioritize this

This vulnerability scores 8.2 (HIGH) due to the combination of complete lack of authentication requirements, network accessibility, high confidentiality impact from database information disclosure, and low attack complexity. The CWE-89 SQL injection classification reflects a well-understood, easily exploitable flaw. Immediate patching or mitigation is essential to prevent data compromise.

Risk score, explained

CVSS 3.1 score of 8.2 reflects: Attack Vector (Network) — remotely exploitable; Attack Complexity (Low) — no special conditions needed; Privileges Required (None) — unauthenticated access; User Interaction (None) — no victim action required; Confidentiality (High) — sensitive database data is exposed; Integrity (Low) — potential for limited data modification; Availability (None) — no denial-of-service component. This HIGH severity rating justifies emergency response prioritization.
