CVE-2026-3042
Published: 24 February 2026
Summary
CVE-2026-3042 is a medium-severity Injection (CWE-74) vulnerability in Admerc Event Management System. Its CVSS base score is 6.9 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 33.9th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2026-3042 is a SQL injection vulnerability in itsourcecode Event Management System 1.0, published on 2026-02-24. The flaw resides in an unknown function within the file /admin/index.php, where manipulation of the ID argument triggers the injection. It 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) and maps to CWEs-74 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-89 (SQL Injection).
Unauthenticated remote attackers can exploit this vulnerability with low attack complexity and no user interaction required. By injecting malicious SQL via the ID parameter, they can achieve limited impacts on confidentiality, integrity, and availability, such as unauthorized data access, modification, or disruption within the application's database.
Advisories and details are available via VulDB entries (https://vuldb.com/?ctiid.347398, https://vuldb.com/?id.347398, https://vuldb.com/?submit.757226), a GitHub issue (https://github.com/ltranquility/cve_submit/issues/1), and the vendor site (https://itsourcecode.com/). The exploit is publicly available and may be used.
The vulnerability's public exploit status increases the risk of active exploitation against unpatched instances of the affected software.

Why these techniques?
SQL injection in a public-facing web app (/admin/index.php) directly matches T1190 for remote unauthenticated exploitation; limited DB impacts (C/I/A) enable T1213.006 for collection from databases.

Directly requires validation and sanitization of untrusted input (the ID parameter) to block SQL injection payloads before they reach the database.
Mandates prompt remediation of the publicly disclosed SQL-injection flaw in /admin/index.php to eliminate the vulnerable code path.
Limits the database privileges of the application account so that a successful injection yields only minimal confidentiality/integrity/availability impact.
