CVE-2025-62423 is a Blind SQL Injection vulnerability categorized under CWE-89, affecting the open-source video hosting platform ClipBucket V5 developed by MacWarrior. The vulnerability exists in the /admin_area/login_as_user.php script within versions 5.5.2 and earlier. Blind SQL Injection occurs when an attacker can send crafted SQL queries to the backend database but does not receive direct query results, instead inferring data based on application behavior or timing. In this case, exploitation requires the attacker to have administrative privileges to access the vulnerable admin area, which limits the attack surface but does not eliminate risk. The vulnerability allows an attacker to inject malicious SQL commands that can lead to unauthorized data disclosure (confidentiality impact), data manipulation (integrity impact), and minor availability impact due to potential database disruptions. The CVSS v3.1 score of 6.7 reflects a medium severity, with attack vector being network-based, low attack complexity, but requiring high privileges and no user interaction. No public exploits or active exploitation have been reported yet. The absence of a patch link suggests that a fix may not have been publicly released at the time of disclosure, emphasizing the need for immediate risk mitigation by administrators. The vulnerability highlights the importance of proper input validation and parameterized queries in PHP applications, especially in sensitive admin modules.

For European organizations, the impact of this vulnerability can be significant, particularly for those using ClipBucket V5 to manage video content and user data. An attacker with admin access exploiting this vulnerability could extract sensitive information such as user credentials, private videos, or internal configuration data, leading to confidentiality breaches. Integrity of the database could also be compromised, allowing unauthorized modification or deletion of content, which could disrupt service and damage organizational reputation. Although availability impact is low, any disruption in video hosting services can affect user experience and business operations, especially for media companies and educational institutions relying on video platforms. The requirement for admin privileges reduces the likelihood of external attackers exploiting this flaw directly but raises concerns about insider threats or compromised admin accounts. European data protection regulations such as GDPR impose strict requirements on data confidentiality and integrity, so exploitation could lead to regulatory penalties and loss of customer trust. Organizations should assess their exposure based on their deployment of ClipBucket and the sensitivity of hosted content.

To mitigate this vulnerability, European organizations should take the following specific actions: 1) Immediately restrict and audit administrative access to the ClipBucket platform, ensuring only trusted personnel have admin privileges. 2) Implement multi-factor authentication (MFA) for admin accounts to reduce the risk of credential compromise. 3) Monitor and log all admin area activities to detect suspicious behavior indicative of exploitation attempts. 4) Apply input validation and parameterized queries in the /admin_area/login_as_user.php script to prevent SQL injection, if source code modification is feasible. 5) Stay alert for official patches or updates from MacWarrior and apply them promptly once available. 6) Consider isolating the admin interface behind VPNs or IP allowlists to limit exposure. 7) Conduct regular security assessments and penetration testing focusing on admin modules. 8) Educate administrators about phishing and social engineering risks that could lead to credential theft. These measures go beyond generic advice by focusing on access control, monitoring, and code-level remediation specific to the vulnerability context.
