CVE-2025-7875 is a vulnerability identified in Metasoft 美特软件 MetaCRM versions up to 6.4.2, specifically involving an improper authentication flaw in the /debug.jsp file. This vulnerability allows an attacker to bypass authentication mechanisms remotely without requiring any privileges or user interaction. The flaw stems from inadequate validation or control over access to the debug.jsp endpoint, which is typically used for diagnostic or debugging purposes but is exposed in a way that permits unauthorized access. The vulnerability is classified with a CVSS 4.0 base score of 6.9, indicating a medium severity level. The vector metrics highlight that the attack can be performed remotely (AV:N), requires no authentication (PR:N), no user interaction (UI:N), and has low impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). The exploit has been publicly disclosed, increasing the risk of exploitation, although no known active exploitation in the wild has been reported yet. The vendor has not responded to the disclosure, and no patches or mitigations have been officially released. This leaves organizations using MetaCRM versions 6.4.0 through 6.4.2 exposed to potential unauthorized access through the debug.jsp endpoint, which could lead to unauthorized data access or manipulation depending on the debug functionality's capabilities.

For European organizations using MetaCRM, this vulnerability poses a risk of unauthorized access to CRM systems, which often contain sensitive customer data, business intelligence, and operational information. Exploitation could lead to data breaches, loss of customer trust, and regulatory non-compliance, especially under GDPR requirements. Even though the impact on confidentiality, integrity, and availability is rated low individually, the ability to bypass authentication remotely without user interaction significantly raises the risk profile. Attackers could leverage this access to gather intelligence, pivot within networks, or prepare for further attacks. The lack of vendor response and absence of patches exacerbate the threat, potentially leading to prolonged exposure. Organizations in sectors with high CRM usage such as finance, retail, and professional services in Europe could face operational disruptions and reputational damage if exploited.

Given the absence of official patches, European organizations should implement immediate compensating controls. First, restrict access to the /debug.jsp endpoint by network-level controls such as firewall rules or web application firewall (WAF) policies to allow only trusted IP addresses or internal networks. Secondly, disable or remove the debug.jsp file if it is not essential for operations. If debugging functionality is required, implement strong authentication and authorization mechanisms around it. Conduct thorough logging and monitoring of access attempts to this endpoint to detect any suspicious activity promptly. Additionally, organizations should consider isolating MetaCRM instances from the public internet or placing them behind VPNs or zero-trust network access solutions. Regularly review and update access controls and conduct penetration testing focused on authentication bypass scenarios. Finally, maintain communication with the vendor for any future patches or advisories and prepare to apply updates promptly once available.
