CVE-2025-10389 is a medium-severity security vulnerability affecting CRMEB versions up to 5.6.1. The flaw exists in the Administrator Password Handler component, specifically within the Save function located in app/services/system/admin/SystemAdminServices.php. The vulnerability arises due to improper authorization checks when handling the 'ID' argument. An attacker can manipulate this argument remotely without requiring user interaction or elevated privileges beyond limited privileges (PR:L). This improper authorization allows unauthorized modification or saving of administrator password data or related sensitive configurations. The vulnerability has a CVSS 4.0 base score of 5.3, indicating a moderate risk with network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:L), and no user interaction (UI:N). The impact affects confidentiality, integrity, and availability to a limited extent (VI:L, VA:L, VC:N). The vendor has not responded to disclosure attempts, and no patches or mitigations have been officially released. Although no known exploits are currently observed in the wild, the public availability of exploit code increases the risk of exploitation. This vulnerability could be leveraged by attackers to escalate privileges or manipulate administrator credentials, potentially leading to unauthorized access or control over the CRMEB system.

For European organizations using CRMEB, especially those running versions 5.6.0 or 5.6.1, this vulnerability poses a tangible risk. CRMEB is a customer relationship management and e-commerce backend system, often used by small to medium enterprises for managing customer data and administrative functions. Exploitation could lead to unauthorized access to administrative accounts, enabling attackers to alter sensitive configurations, access confidential customer data, or disrupt business operations. This could result in data breaches, regulatory non-compliance (e.g., GDPR violations), reputational damage, and financial losses. Since the attack can be initiated remotely without user interaction, organizations with internet-facing CRMEB instances are particularly vulnerable. The lack of vendor response and absence of patches increases the window of exposure. European organizations in sectors such as retail, services, and SMBs that rely on CRMEB for customer management are at risk of targeted attacks or opportunistic exploitation.

Given the absence of official patches, European organizations should implement immediate compensating controls. First, restrict network access to the CRMEB administrative interface by using firewalls, VPNs, or IP whitelisting to limit exposure to trusted users only. Second, enforce strong authentication mechanisms and monitor administrative account activities for anomalies. Third, conduct thorough audits of CRMEB installations to identify affected versions and upgrade to later versions once patches become available. Until then, consider disabling or restricting the vulnerable Save function if feasible. Additionally, implement web application firewalls (WAFs) with custom rules to detect and block suspicious requests manipulating the 'ID' parameter. Regularly review logs for unauthorized access attempts and prepare incident response plans. Organizations should also engage with CRMEB vendors or community forums to track patch releases and share threat intelligence.
