CVE-2025-22347 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability found in the Bannersky BSK Forms Blacklist plugin. This vulnerability allows attackers to launch Blind SQL Injection attacks, potentially leading to unauthorized access to sensitive data. The CVSS score for this vulnerability is 8.2, categorizing it as high risk due to its significant impact on confidentiality.
The vulnerability affects all versions of BSK Forms Blacklist up to version 3.9. The presence of a CSRF vulnerability, combined with the potential for Blind SQL Injection, increases the urgency for organizations utilizing this plugin to take immediate action.
Organizations using the BSK Forms Blacklist plugin should prioritize patching this vulnerability as it poses a significant risk to data integrity and confidentiality. The potential for exploitation through network vectors underscores the need for rapid remediation.
Given the high severity score and the potential impact of this vulnerability, organizations should assess their exposure and take corrective measures without delay.
Vulnerability Details
The official description of this vulnerability states that it is a Cross-Site Request Forgery (CSRF) vulnerability in the Bannersky BSK Forms Blacklist plugin, allowing Blind SQL Injection. The vulnerability was published on January 7, 2025, and affects versions of the plugin from n/a through 3.9. The CWE classification for this vulnerability is CWE-352.
The CVSS score of 8.2 indicates a high severity level, which is primarily due to the potential confidentiality impact being high, while integrity is none and availability is low. The attack vector is classified as NETWORK, requiring low complexity and no privileges for the attacker, but user interaction is required.
Technical Analysis
The root cause of this vulnerability stems from improper validation of user input, which can allow an attacker to craft a malicious request that exploits the CSRF vulnerability. The attack vector is network-based, allowing remote attackers to exploit the vulnerability without physical access.
The attack complexity is low, as attackers do not require any special conditions to exploit this vulnerability. Privileges required are none, and user interaction is required, meaning the victim must be tricked into clicking on a malicious link or visiting a compromised page.
The confidentiality impact is high since successful exploitation could allow attackers to read sensitive data from the database. However, there is no integrity impact, and availability is low, indicating that the system would remain operational regardless of the exploit.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to sensitive data through Blind SQL Injection. Given the high CVSS score, organizations should assess their exposure and prioritize remediation efforts. The blast radius of this vulnerability can be extensive, affecting all users of the BSK Forms Blacklist plugin.
Organizations are advised to address this vulnerability in their priority patch cycle to mitigate any potential risks. The urgency of this vulnerability is further emphasized by its classification within the high severity range.
