CVE-2018-25420: SQL Injection in AiOPMSD Final 1.0.0 – CVSS 8.2 HIGH

Technical summary

CVE-2018-25420 is an unauthenticated SQL injection vulnerability in AiOPMSD Final 1.0.0 affecting the watch.php script. The 'id' parameter fails to sanitize user input, allowing attackers to inject arbitrary SQL commands via GET requests. The CWE-89 classification confirms improper neutralization of special elements used in an SQL command. Attack surface is network-accessible, requires no privileges or user interaction, and can result in unauthorized database access and information disclosure.

Business impact

Successful exploitation enables attackers to bypass authentication, enumerate database schemas, extract user credentials, and retrieve sensitive application data. In a production environment, this could lead to account takeover, regulatory compliance violations (depending on data classification), reputational damage, and potential lateral movement if database credentials are reused across systems. The high CVSS score (8.2) reflects substantial risk to data confidentiality.

Affected systems

AiOPMSD Final version 1.0.0 is the confirmed affected release. Organizations running this application in any environment—development, staging, or production—should be considered at risk. Verify your deployment version matches 1.0.0 and assess whether watch.php is accessible from your threat model (internet-facing, internal network, DMZ, etc.).

Exploitability

Exploitability is high. The vulnerability requires only network access and no authentication. Attackers can craft simple GET requests with SQL payloads and execute them immediately; no interaction from legitimate users is needed. The barrier to entry is low for anyone with basic SQL injection knowledge. However, this vulnerability is not currently tracked in the CISA Known Exploited Vulnerabilities (KEV) catalog, which may indicate limited public exploit availability or awareness—but organizations should not rely on obscurity as a security control.

Remediation

Immediate action is required. Upgrade AiOPMSD Final to a patched version released after 1.0.0 (verify availability with the vendor), or if upgrades are not immediately feasible, implement Web Application Firewall (WAF) rules to block SQL injection patterns in the 'id' parameter, restrict network access to watch.php via IP allowlisting or network segmentation, and apply input validation and parameterized query patterns if code modification is possible.

Patch guidance

Contact the AiOPMSD vendor or check their official advisory for patch availability and upgrade procedures. The vulnerability was modified on 2026-06-17, which may indicate vendor activity. Obtain patches only from official channels and test in a non-production environment before production rollout. If the vendor has not released a patch, escalate to your vendor support and consider interim mitigations listed above.

Detection guidance

Monitor watch.php access logs for anomalous 'id' parameter values containing SQL metacharacters (single quotes, double dashes, UNION, SELECT, etc.). Deploy WAF or IDS rules to flag SQL injection attempts. Query your application logs for failed or unusual database queries and check database audit logs for unexpected command execution. Consider enabling SQL query logging if available. Review recent database access patterns for anomalies that might indicate prior exploitation.

Why prioritize this

This vulnerability merits high-priority remediation due to its combination of high CVSS score (8.2), unauthenticated attack vector, and direct impact on data confidentiality. SQL injection is a foundational attack class; exploitation is straightforward and can expose sensitive data or credentials immediately. Organizations running 1.0.0 should prioritize patching or implementing interim controls within days, not weeks.

Risk score, explained

CVSS 3.1 score of 8.2 (HIGH) reflects: network-accessible attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction needed (UI:N), high confidentiality impact (C:H), low integrity impact (I:L), and no availability impact (A:N). The confidentiality concern dominates, as attackers can extract database contents. Integrity is low because SQL injection typically allows SELECT queries more easily than UPDATE/DELETE. Availability is unaffected unless the attacker deliberately corrupts or locks the database.
