Deeper analysis

CVE-2025-30843 is an Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability, classified under CWE-89, affecting the bizcalendar-web WordPress plugin developed by Setriosoft. The issue impacts versions of bizcalendar-web from an unspecified initial version through 1.1.0.34. Published on 2025-03-27, it carries a CVSS v3.1 base score of 7.6.

Exploitation requires high privileges (PR:H) but is network-accessible (AV:N) with low attack complexity (AC:L), no user interaction (UI:N), and a changed scope (S:C). An attacker with sufficient privileges can inject malicious SQL commands, resulting in high confidentiality impact (C:H) such as data extraction, with no integrity impact (I:N) and low availability impact (A:L).

Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly prevents SQL injection by requiring validation of information inputs to neutralize special elements used in SQL commands within the bizcalendar-web plugin.

SI-2 Flaw Remediation good match
prevent

Mandates timely identification, reporting, and correction of the SQL injection flaw in bizcalendar-web versions through 1.1.0.34 via patching.

AC-6 Least Privilege partial match
prevent

Enforces least privilege to limit high-privilege accounts (PR:H) capable of exploiting the network-accessible SQL injection vulnerability.
