CVE-2025-0308 affects the Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin plugin for WordPress. This vulnerability allows for a time-based SQL Injection via the search parameter in all versions up to, and including, 2.9.1. Due to insufficient escaping on user-supplied parameters and a lack of adequate preparation on the existing SQL query, unauthenticated attackers can append additional SQL queries to existing queries, potentially extracting sensitive information from the database.
With a CVSS score of 7.5, classified as high severity, this vulnerability poses significant risks. Attackers may leverage this flaw to gain unauthorized access to confidential data, which can lead to severe repercussions for organizations utilizing this plugin. Given the ease of exploitation, organizations should prioritize patching immediately.
The vulnerability was published on January 18, 2025, and has been analyzed thoroughly. Organizations using versions of the Ultimate Member plugin prior to 2.9.2 are strongly advised to upgrade to mitigate the risk associated with this vulnerability.
In addition, monitoring for any unusual database activities and implementing access controls can further help in minimizing risk exposure. Understanding the implications of such vulnerabilities can aid in better preparation against potential attacks.
Vulnerability Details
The Ultimate Member plugin is a widely used solution in WordPress for user management. The identified SQL Injection vulnerability is categorized under CWE-89, indicating its nature as a SQL Injection issue. The attack vector is network-based, with low complexity and no required privileges or user interaction, which further increases its risk profile.
The vulnerability is characterized by a high confidentiality impact, as attackers can potentially access sensitive information stored in the database. However, there is no integrity or availability impact associated with this vulnerability.
Technical Analysis
The root cause of this vulnerability lies in the insufficient escaping of user-supplied parameters in SQL queries. When the search parameter is not properly sanitized, it allows attackers to manipulate the SQL command executed by the database. This manipulation can lead to unauthorized data exposure.
The attack vector is primarily network-based, meaning it can be exploited remotely without requiring physical access to the server. The complexity of the attack is low, allowing even minimally skilled attackers to exploit the vulnerability. No privileges or user interactions are necessary to carry out the attack.
Given the nature of the vulnerability, organizations must implement strong input validation and sanitization protocols to prevent similar issues. Continuous monitoring for unusual database queries and ensuring that all user inputs are correctly escaped will be crucial in mitigating the risk.
Risk & Impact Analysis
Risk to organizations includes potential exposure of sensitive user data, which can lead to data breaches, loss of customer trust, and regulatory penalties. The blast radius of this vulnerability extends to any organization relying on the affected plugin, with the potential for widespread data leaks.
Organizations should assess their deployment of the Ultimate Member plugin and prioritize patching in their update cycles. Given the high severity and the potential for exploitation, rapid remediation efforts are essential to protect sensitive information.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
All versions of the Ultimate Member plugin for WordPress prior to 2.9.2 are affected by this vulnerability. Organizations should ensure they are using the latest version to mitigate the risks associated with this issue.
Mitigation & Remediation
To remediate this vulnerability, organizations should upgrade to version 2.9.2 or later of the Ultimate Member plugin. If patching is not immediately possible, implementing input validation and sanitization measures is critical. Additionally, organizations may consider deploying web application firewalls (WAFs) to help filter out malicious requests targeting this vulnerability. For further assistance, organizations can engage in penetration testing to evaluate their security posture and identify potential weaknesses.
Detection Guidance
Monitoring for unusual database queries and user behavior can be crucial in detecting exploitation attempts. Organizations should look for anomalies in login attempts and sudden spikes in database query execution times. Logging database interactions and setting up alerts for suspicious activities can also aid in early detection.
AppSecure Threat Intelligence Insight
The emergence of CVE-2025-0308 highlights the ongoing challenges organizations face in managing third-party plugin vulnerabilities. As seen with this vulnerability, insufficient input validation can lead to significant exposure risks. Organizations must adopt a proactive stance in their security practices, including regular vulnerability assessments and updates to third-party components.
Security teams are encouraged to review their application security testing practices, ensuring that input validation is a core focus area. Resources such as the penetration testing methodology can provide valuable insights into effective strategies for identifying and remediating vulnerabilities.
Finally, organizations should stay informed about trends in vulnerabilities and threats by reviewing materials such as the vulnerability management program design to enhance their overall security posture.
