CVE-2025-46610 is a high-severity vulnerability identified in ARTEC EMA Mail version 6.92, characterized as a Cross-Site Request Forgery (CSRF) flaw (CWE-352). CSRF vulnerabilities allow attackers to trick authenticated users into submitting unwanted requests to a web application in which they are currently authenticated. This can lead to unauthorized actions being performed on behalf of the user without their consent. The CVSS 3.1 base score of 8.8 reflects the critical nature of this vulnerability, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The scope is unchanged (S:U), and the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). This means an attacker can remotely exploit the vulnerability without needing prior authentication, but the victim must interact with a malicious link or webpage. Successful exploitation could allow an attacker to execute arbitrary commands or manipulate email system settings, potentially leading to data leakage, unauthorized email sending, or disruption of email services. Although no known exploits are currently reported in the wild and no patches have been linked yet, the vulnerability's presence in a mail system product suggests significant risk, especially given the critical role of email in organizational communications and operations.

For European organizations, the impact of this CSRF vulnerability in ARTEC EMA Mail 6.92 could be substantial. Email systems are central to business communications, and compromise can lead to unauthorized disclosure of sensitive information, manipulation of email content, or disruption of email services. Given the high confidentiality, integrity, and availability impacts, exploitation could result in data breaches affecting personal data protected under GDPR, leading to regulatory penalties and reputational damage. Additionally, attackers could use compromised email systems to launch phishing campaigns internally or externally, further amplifying risk. The fact that no authentication is required lowers the barrier for attackers, increasing the likelihood of exploitation if the product is widely used. The requirement for user interaction means social engineering or phishing tactics could be employed to trigger the exploit. European organizations relying on ARTEC EMA Mail 6.92 should consider this vulnerability a significant threat to their email infrastructure security and overall operational continuity.

To mitigate this vulnerability effectively, European organizations should: 1) Immediately identify and inventory all instances of ARTEC EMA Mail 6.92 in their environment. 2) Monitor vendor communications closely for official patches or updates addressing CVE-2025-46610 and apply them promptly upon release. 3) Implement Web Application Firewall (WAF) rules to detect and block suspicious CSRF attempts targeting the mail system interfaces. 4) Enforce strict Content Security Policy (CSP) and SameSite cookie attributes to reduce CSRF attack surface. 5) Educate users about the risks of interacting with unsolicited links or emails, emphasizing caution with email system interfaces. 6) Consider deploying multi-factor authentication (MFA) for access to the mail system to add an additional layer of defense, even though the vulnerability does not require authentication. 7) Conduct regular security assessments and penetration testing focused on email infrastructure to detect potential exploitation attempts. 8) Implement network segmentation to isolate the mail system from less trusted network zones, limiting attacker movement if exploited.
