CVE-2018-25414: Unauthenticated SQL Injection in AiOPMSD Final 1.0.0

Technical summary

The vulnerability (CWE-89: Improper Neutralization of Special Elements used in an SQL Command) exists in the actor parameter of actor.php. The application fails to properly sanitize or parameterize user input before constructing SQL queries. An unauthenticated attacker can inject SQL metacharacters and logic to break out of the intended query context and execute arbitrary commands. The attack vector is network-accessible and requires no privileges or user interaction, making it trivial to exploit at scale.

Business impact

Successful exploitation leads to unauthorized database access and disclosure of sensitive information including user credentials, database schema details, and system version information. This data exposure can facilitate further attacks such as privilege escalation, lateral movement, or targeted credential compromise. For organizations running AiOPMSD Final 1.0.0 in production environments, this vulnerability directly undermines data confidentiality and could trigger compliance violations (GDPR, HIPAA, PCI-DSS depending on data stored) and mandatory breach notification obligations.

Affected systems

AiOPMSD Final version 1.0.0 is affected. The vulnerability resides in the actor.php endpoint and is reachable via HTTP GET requests. Any deployment of this specific version—whether on public-facing or internal networks—is vulnerable if the application is accessible from an attacker's network position.

Exploitability

This vulnerability is highly exploitable. It requires no authentication, no special network configuration, and no user interaction. An attacker can immediately craft and send a GET request to actor.php with a SQL injection payload in the actor parameter to begin extracting data. The attack is deterministic and reliable; once the endpoint is identified, exploitation typically succeeds on first attempt. The barrier to entry is low—basic SQL injection knowledge and HTTP tools suffice.

Remediation

Upgrade AiOPMSD Final to a patched version as released by the vendor. If an immediate patch is unavailable, implement network-level access controls to restrict access to actor.php to trusted networks only, and consider disabling or removing the vulnerable endpoint if operationally feasible. Do not rely solely on input filtering; parameterized queries or prepared statements in the application code are the definitive fix.

Patch guidance

Check the vendor's security advisory and release notes for AiOPMSD Final to identify the patched version. Apply the update in a test environment first to validate compatibility and functionality. Verify against the vendor advisory for specific version numbers and deployment instructions. Once patched, restart all affected instances and confirm that the actor parameter no longer accepts SQL injection payloads (via your security testing team).

Detection guidance

Monitor HTTP access logs for GET requests to actor.php containing SQL metacharacters (single quotes, double dashes, semicolons, UNION, SELECT, DROP, etc.) in the actor parameter. Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns targeting actor.php. Implement SQL query logging at the database layer to identify unexpected or malicious query execution. Search network traffic and application logs for evidence of reconnaissance (e.g., attempts to extract version or schema information via SQL injection).

Why prioritize this

This is a high-severity, unauthenticated remote code execution risk for database confidentiality. The CVSS 3.1 score of 8.2 reflects the ease of exploitation (network-accessible, no privileges needed), the high impact on data confidentiality, and the broad attack surface. Any organization running AiOPMSD Final 1.0.0 should treat this as urgent and patch within days, not weeks.

Risk score, explained

The CVSS 3.1 score of 8.2 (HIGH) is driven by: (1) Attack Vector: Network—exploitable remotely; (2) Attack Complexity: Low—straightforward SQL injection, no special conditions; (3) Privileges Required: None—unauthenticated access; (4) User Interaction: None—attacker acts directly; (5) Scope: Unchanged—impact is to the vulnerable component; (6) Confidentiality Impact: High—sensitive database information is extractable; (7) Integrity Impact: Low—while SQL injection can allow data modification, the primary attack vector is read-access; (8) Availability Impact: None—the vulnerability does not cause denial of service. The score appropriately reflects a critical data disclosure risk that demands rapid remediation.
