Vulnerability Details
This vulnerability allows for improper neutralization of input during web page generation, specifically allowing reflected XSS. The CVSS score is 7.1, indicating a high severity classification. The affected product is the MJ Contact Us plugin, with the vulnerability published on January 24, 2025. The Common Weakness Enumeration (CWE) classification for this vulnerability is CWE-79.
Technical Analysis
The root cause of this vulnerability lies in the failure to properly sanitize user input within the MJ Contact Us plugin. Attackers can exploit this weakness by crafting a malicious link that, when clicked by a user, executes arbitrary scripts in their browser. The attack vector is through the network, requiring low attack complexity and no privileges. User interaction is required for exploitation, as the user must click on the malicious link.
The impact of this vulnerability includes low confidentiality, integrity, and availability impacts, meaning that while sensitive data may not be directly compromised, the potential for unauthorized actions exists.
Risk & Impact Analysis
Organizations using the MJ Contact Us plugin should assess the risk of this vulnerability. The potential for exploitation through XSS could lead to unauthorized access and data manipulation. Given the ease of exploitation, attackers may leverage this vulnerability to carry out phishing attacks or redirect users to malicious sites.
Organizations should prioritize this vulnerability in their patch cycles, considering the implications of a successful attack on their reputation and customer trust. The urgency for remediation is high due to the nature of XSS vulnerabilities and the potential blast radius.
