Vulnerability Details
The vulnerability, characterized as 'Improper Neutralization of Input During Web Page Generation (CWE-79)', affects the WordPress File Search plugin by markcoker. The specific issue allows for reflected XSS, which can be exploited by an attacker to execute scripts in the context of the user’s browser. This vulnerability affects all versions of WordPress File Search up to and including version 1.2.
The vulnerability was published on January 22, 2025, and has been classified with a CVSS v3.1 score of 7.1, indicating high severity. The attack vector is network-based, and the attack complexity is low, with no privileges required for exploitation. The confidentiality, integrity, and availability impacts are all rated as low.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of user input during the generation of web pages. When user input is not adequately sanitized, it can allow attackers to inject malicious scripts. The attack vector is through the network, allowing exploitation over the internet. The attack complexity is low, meaning that attackers can easily craft their requests without advanced methods.
Exploitation requires user interaction, as the victim must access a malicious link that triggers the XSS. Once exploited, attackers can potentially gain access to session cookies or redirect users to malicious sites, compromising user data and integrity.
Risk & Impact Analysis
The risk posed by CVE-2025-23867 is significant due to the prevalence of WordPress and the common use of plugins in web applications. Organizations using the affected WordPress File Search plugin should recognize that the impact of XSS vulnerabilities can extend beyond immediate data loss; they can damage user trust and lead to compliance issues.
The blast radius for this vulnerability could encompass any user who interacts with the compromised web application. Given the nature of reflected XSS, the potential for widespread exploitation exists, especially if combined with social engineering tactics.
Organizations should assess their exposure based on the CVSS score of 7.1 and prioritize remediation efforts. The urgency of addressing this vulnerability is high, considering the potential for exploitation by malicious actors.
