CVE-2025-50926 is a SQL injection vulnerability identified in Easy Hosting Control Panel (EHCP) version 20.04.1.b. The vulnerability exists in the 'List All Email Addresses' function, specifically via the 'id' parameter. SQL injection (CWE-89) occurs when untrusted input is improperly sanitized and directly included in SQL queries, allowing an attacker to manipulate the backend database queries. In this case, the 'id' parameter can be exploited remotely without authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). This means an attacker can send crafted requests over the network to execute arbitrary SQL commands. The CVSS base score is 6.5, reflecting a medium severity level with potential impacts on confidentiality and integrity but no direct impact on availability. Exploiting this vulnerability could allow an attacker to extract sensitive information such as user credentials, email addresses, or other stored data, or potentially modify database contents, depending on the database permissions. No known exploits are currently reported in the wild, and no official patches or mitigation links are provided yet. The vulnerability was reserved in June 2025 and published in August 2025, indicating it is a recent discovery. EHCP is an open-source web hosting control panel used to manage hosting services, including email and domain management, which makes this vulnerability particularly relevant for hosting providers and organizations managing their own hosting infrastructure.

For European organizations, the impact of this vulnerability can be significant, especially for small to medium hosting providers and enterprises that use EHCP to manage their hosting environments. Successful exploitation could lead to unauthorized disclosure of customer data, including email addresses and potentially other sensitive information stored in the database. This could result in privacy violations under GDPR, leading to regulatory fines and reputational damage. Additionally, attackers could manipulate or corrupt email-related data, disrupting communication services. While availability is not directly affected, the integrity and confidentiality breaches could undermine trust in hosting services. Organizations relying on EHCP for email and hosting management should be aware of the risk of data leakage and potential lateral movement if attackers gain further access through compromised credentials or data. The lack of authentication requirement and ease of exploitation increase the threat level, particularly for externally accessible EHCP instances.

Given the absence of official patches, European organizations should implement immediate compensating controls. First, restrict network access to the EHCP interface by limiting exposure to trusted IP addresses or internal networks only, using firewall rules or VPNs. Second, implement web application firewalls (WAFs) with SQL injection detection and prevention rules tailored to the EHCP environment to block malicious payloads targeting the 'id' parameter. Third, conduct thorough input validation and sanitization on the 'id' parameter if custom modifications are possible. Fourth, monitor EHCP logs for unusual query patterns or repeated failed attempts that may indicate exploitation attempts. Fifth, consider isolating EHCP servers from critical infrastructure to limit lateral movement in case of compromise. Finally, stay alert for official patches or updates from EHCP maintainers and apply them promptly once available. Regular backups of the database should be maintained to enable recovery in case of data tampering.
