CVE-2025-62938 is a missing authorization vulnerability identified in Reoon Technology's Reoon Email Verifier software, affecting versions up to and including 2.0.1. The flaw stems from incorrectly configured access control security levels, which allow attackers with low privileges (PR:L) to remotely exploit the system over the network (AV:N) without requiring user interaction (UI:N). This vulnerability enables unauthorized access to sensitive operations or data within the email verification platform, compromising confidentiality and integrity of the system. The CVSS v3.1 base score is 8.1, reflecting high severity due to the ease of exploitation and significant impact on data confidentiality and integrity, although availability remains unaffected. The vulnerability does not require elevated privileges beyond low-level access, making it easier for attackers who have some access to the system to escalate their capabilities. No public exploits have been reported yet, but the vulnerability is published and should be considered a critical risk for organizations relying on this product for email verification tasks. The lack of patch links indicates that a fix may not yet be available, emphasizing the need for immediate mitigation measures.

For European organizations, this vulnerability poses a significant risk to the confidentiality and integrity of email verification data, which often includes sensitive customer information and business-critical communication details. Exploitation could lead to unauthorized access to verified email lists, manipulation of verification results, or exposure of internal processes, potentially facilitating further phishing or social engineering attacks. Organizations in sectors such as marketing, finance, healthcare, and e-commerce that rely heavily on accurate and secure email verification services are particularly vulnerable. The breach of trust in email verification data could damage reputations, lead to regulatory non-compliance (e.g., GDPR violations), and cause financial losses. Since the vulnerability is remotely exploitable without user interaction, attackers could leverage it as an initial foothold or lateral movement vector within corporate networks.

Organizations should immediately audit their use of Reoon Email Verifier and restrict access to the application to trusted users and networks only. Implement network segmentation and firewall rules to limit exposure of the email verifier service to the internet or untrusted zones. Monitor logs for unusual access patterns or privilege escalations related to the email verifier. Until an official patch is released by Reoon Technology, consider disabling or isolating the vulnerable service where feasible. Employ strong authentication and authorization mechanisms around the email verifier interface, including multi-factor authentication and role-based access controls. Regularly update and review access control configurations to ensure no unauthorized privileges are granted. Engage with the vendor for timely patch deployment and subscribe to vulnerability advisories for updates. Additionally, conduct penetration testing focused on access control weaknesses to identify and remediate similar issues proactively.
