CVE-2026-3042 Exploited in itsourcecode Event Management System

In a rapidly evolving threat landscape, CVE-2026-3042 has emerged as a high-risk SQL injection vulnerability in the itsourcecode Event Management System version 1.0.

Published on February 23, 2026, this flaw carries a CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L), indicating significant danger due to its remote exploitability without authentication.

While no widespread exploitation has been confirmed yet, a public exploit is now available, urging immediate action from affected organizations.

CVE-2026-3042 Vulnerability

The issue resides in an unidentified function within /admin/index.php. Attackers manipulate the ID argument to inject malicious SQL payloads, bypassing normal query structures.

This classic CWE-89 SQL injection allows unauthorized access to the underlying database, potentially exposing sensitive event records, user credentials, attendee data, and more.

The vector confirms network accessibility (AV: N), low attack complexity (AC: L), no privileges required (PR: N), and no user interaction required (UI: N). Scope remains unchanged (S: U), but impacts span confidentiality (C:L), integrity (I:L), and availability (A:L). Proof-of-concept exploits, referenced in VulDB entries and a GitHub issue, demonstrate straightforward remote execution.

This isn’t theoretical; public exploit availability elevates it to high risk. Opportunistic attackers can probe internet-facing instances for quick wins, leading to data exfiltration, tampering with event schedules, or denial-of-service via resource exhaustion.

Small to medium businesses relying on this open-source system for conferences, webinars, or ticketing face the brunt, as admin panels are often left exposed. Customer trust erodes fast when personal data leaks, and regulatory fines (GDPR, CCPA) loom large.

Attackers craft payloads like ' OR 1=1-- into the ID parameter via GET/POST requests to /admin/index.php?id=<payload>. Success yields SQL errors, dumped tables, or manipulated records. Detection hinges on proactive monitoring:

• Anomalous traffic: Repeated probes to /admin/index.php with encoded payloads (e.g., UNION SELECT, time-based blinds).
• Log signatures: SQL errors like “syntax error near”, unusual query durations, or spikes in DB connections from admin endpoints.
• Tooling: WAF/IPS rules for SQLi (e.g., ModSecurity CRS), SIEM alerts on IOCs from VulDB (CTI-347398), or EDR for query anomalies.
• Network: Suricata/Zeek rules flagging HTTP params with SQL keywords.

Primarily on-premises or misconfigured cloud deployments of Event Management System 1.0 with public admin access. Scan your estate via Shodan or Censys for /admin/index.php exposures.

Prioritize ruthlessly; treat as P1 if EPSS ≥ 0.5 or KEV-listed.

1. Patch Immediately: Fetch updates from itsourcecode.com; test in staging first.
2. Interim Defenses: IP allowlist admin access, enforce VPN/MFA, or turn off direct exposure via reverse proxy.
3. Code Hardening: Retrofit parameterized queries (e.g., PDO in PHP: $stmt->bindParam(':id', $id);), input sanitization (filter_var), and least-privilege DB accounts.
4. WAF Boost: Deploy SQLi blocks; OWASP CRS set covers this.
5. Post-Fix: Hunt for IOCs, rotate creds, and audit logs for prior attempts.
