CVE-2025-7429 identifies a stored Cross-Site Scripting (XSS) vulnerability classified under CWE-79 in Zohocorp's ManageEngine Exchange Reporter Plus software, specifically in versions 5723 and earlier. The vulnerability arises from improper neutralization of user-supplied input during web page generation within the 'Mails Deleted or Moved' report feature. This flaw allows an attacker with low-level privileges to inject malicious JavaScript code that is persistently stored on the server and subsequently executed in the browsers of users who view the affected report. The CVSS 3.1 base score of 7.3 indicates a high-severity issue, with an attack vector of network (AV:N), low attack complexity (AC:L), requiring privileges (PR:L), and user interaction (UI:R). The impact affects confidentiality and integrity (C:H/I:H) but not availability (A:N). Exploiting this vulnerability could enable attackers to steal session tokens, perform actions on behalf of legitimate users, or pivot further into the network. Although no known exploits have been reported in the wild yet, the vulnerability's presence in a widely used enterprise reporting tool for Microsoft Exchange environments makes it a significant concern. The lack of available patches at the time of publication necessitates immediate attention to mitigation strategies. The vulnerability was reserved in July 2025 and published in November 2025, indicating recent discovery and disclosure. The ManageEngine Exchange Reporter Plus product is commonly used in enterprise environments to monitor and report on Exchange server activities, making the vulnerability relevant to organizations with substantial email infrastructure.

For European organizations, this vulnerability poses a significant risk to the confidentiality and integrity of email monitoring data and potentially broader network security. Attackers exploiting this stored XSS could hijack user sessions, steal sensitive information, or execute unauthorized actions within the reporting tool's context. Given that ManageEngine Exchange Reporter Plus integrates with Microsoft Exchange environments, compromise could lead to exposure of sensitive email metadata and user credentials. This could facilitate further lateral movement or data exfiltration within corporate networks. The requirement for low privileges and user interaction lowers the barrier for exploitation, increasing risk especially in environments with multiple administrators or users accessing the reporting interface. Organizations relying on this tool for compliance and security monitoring may face operational disruptions and regulatory compliance challenges if the vulnerability is exploited. The absence of known exploits currently provides a window for proactive mitigation, but the high severity score underscores the urgency for European entities to address this threat promptly.

1. Monitor Zohocorp's official channels for the release of security patches addressing CVE-2025-7429 and apply them immediately upon availability. 2. Until patches are available, restrict access to the ManageEngine Exchange Reporter Plus web interface to trusted administrators only, using network segmentation and firewall rules. 3. Implement Web Application Firewall (WAF) rules to detect and block suspicious input patterns targeting the 'Mails Deleted or Moved' report functionality. 4. Conduct thorough input validation and output encoding on all user-supplied data within the reporting tool, if customization or interim fixes are possible. 5. Educate users with access to the reporting tool about the risks of interacting with untrusted content and encourage cautious behavior to reduce user interaction exploitation vectors. 6. Review and tighten privilege assignments to minimize the number of users with rights to generate or view vulnerable reports. 7. Regularly audit logs and monitor for unusual activities or signs of exploitation related to the reporting tool. 8. Consider deploying Content Security Policy (CSP) headers to mitigate the impact of potential XSS attacks by restricting script execution sources.
