CVE-2018-25414 Overview
CVE-2018-25414 is an SQL injection vulnerability in AiOPMSD Final 1.0.0, an open-source project distributed through SourceForge. The flaw resides in actor.php, which fails to sanitize input passed through the actor GET parameter before incorporating it into an SQL query. Unauthenticated attackers can send crafted requests to extract database contents, including usernames, database names, and version information. The issue is tracked under CWE-89: Improper Neutralization of Special Elements used in an SQL Command.
Critical Impact
Remote, unauthenticated attackers can exfiltrate sensitive database contents from any internet-reachable AiOPMSD Final 1.0.0 instance through a single HTTP GET request.
Affected Products
- AiOPMSD Final 1.0.0
- Deployments using actor.php with the unsanitized actor parameter
- Installations sourced from the AIOPMSD SourceForge project

Technical Details for CVE-2018-25414
Vulnerability Analysis
The vulnerability stems from direct concatenation of user-controlled input into an SQL statement within actor.php. The application accepts a value via the actor GET parameter and embeds it into a query without parameterization or input filtering. An attacker can append SQL syntax such as UNION SELECT to read arbitrary columns from accessible tables. Because the endpoint is reachable without authentication, exploitation requires no credentials or user interaction.
Published proof-of-concept material referenced in Exploit-DB entry 45690 and the VulnCheck SQL Injection Advisory demonstrates retrieval of user(), database(), and version() output. The same primitive permits dumping of credential tables and application records, depending on the privileges granted to the database account configured for the application.
Root Cause
The root cause is the absence of prepared statements or parameterized queries in actor.php. Input is interpolated into the SQL string verbatim, allowing the parser to treat attacker-supplied content as query logic rather than data.
Attack Vector
Exploitation occurs over the network through standard HTTP. The attacker issues a GET request to actor.php with a malicious payload appended to the actor query string parameter. No session, cookie, or pre-existing account is required. Standard union-based and error-based SQL injection techniques apply.
No verified exploit code is reproduced here. Refer to the Exploit-DB #45690 and VulnCheck advisory for technical payload details.
Detection Methods for CVE-2018-25414
Indicators of Compromise
- Web server access logs containing GET requests to actor.php with SQL keywords such as UNION, SELECT, SLEEP, or INFORMATION_SCHEMA in the actor parameter
- URL-encoded SQL meta-characters (%27, %20OR%20, --) appearing in the actor parameter value
- Unusual database query patterns referencing user(), database(), or version() from the application's database account
- Sudden spikes in response sizes or HTTP 500 errors from actor.php
Detection Strategies
- Deploy web application firewall (WAF) rules to flag SQL meta-characters and tautologies in the actor parameter
- Enable database query logging and alert on queries referencing schema metadata originating from the AiOPMSD database user
- Correlate web access logs with database audit logs to identify injection attempts that produced successful responses
Monitoring Recommendations
- Forward web server, WAF, and database audit logs into a centralized analytics platform for cross-source correlation
- Establish baselines for legitimate actor.php request patterns and alert on deviations such as long query strings or encoded payloads
- Monitor outbound traffic from the web host for signs of data exfiltration following suspicious requests
How to Mitigate CVE-2018-25414
Immediate Actions Required
- Restrict network access to AiOPMSD Final 1.0.0 instances, placing them behind authenticated reverse proxies or VPNs until remediated
- Apply a WAF rule that blocks SQL injection patterns in the actor parameter of actor.php
- Audit web and database logs for prior exploitation attempts and rotate any credentials stored in the application's database
- Reduce database account privileges to the minimum required by the application
Patch Information
No vendor patch is referenced in the NVD record at the time of publication. AiOPMSD is distributed via SourceForge; operators should monitor the project page for updated releases and consider migrating to actively maintained alternatives.
Workarounds
- Modify actor.php to use parameterized queries or prepared statements instead of string concatenation
- Add server-side input validation to reject non-numeric or non-whitelisted values for the actor parameter
- Disable or remove the actor.php endpoint if it is not required for production use
- Place the application behind authentication and restrict access by source IP
