Vulnerability Details

The vulnerability allows Cross-Site Request Forgery (CSRF) in Erik AntiSpam for Contact Form 7. The affected versions range from n/a through <= 0.6.3. The CVSS score of 5.4 indicates medium severity, with impacts on integrity and availability classified as low. The vulnerability falls under the Common Weakness Enumeration (CWE) ID CWE-352.

Technical Analysis

The root cause of this vulnerability lies in the lack of proper CSRF protection mechanisms in the plugin. Attackers can exploit this vulnerability by tricking users into submitting unauthorized requests through a web interface. The attack vector is network-based, requiring low complexity, and does not require any privileges or user interaction. The potential impact includes low integrity and availability risks.

Risk & Impact Analysis

Risk to organizations includes unauthorized actions executed in the context of authenticated users, which could lead to data manipulation or loss. The blast radius potential is moderate, especially for organizations relying heavily on the affected plugin for managing contact forms. Organizations should assess their exposure to this vulnerability and consider the urgency of remediation based on their deployment context.

Exploitation Status

Affected Versions

All versions prior to vendor patch, specifically AntiSpam for Contact Form 7 from n/a through <= 0.6.3, are affected by this vulnerability.

Mitigation & Remediation
