CVE-2025-7632 is a stored Cross-Site Scripting (XSS) vulnerability classified under CWE-79, found in Zohocorp's ManageEngine Exchange Reporter Plus product, specifically affecting versions 5723 and earlier. The vulnerability resides in the Public Folders report component, where user-supplied input is not properly sanitized or neutralized before being embedded into web pages generated by the application. This improper input handling allows an attacker with low-level privileges to inject malicious JavaScript code that is stored persistently on the server and executed in the browsers of users who view the affected reports. The vulnerability requires the attacker to have some level of authenticated access (PR:L) and user interaction (UI:R) to trigger the malicious payload. The CVSS 3.1 score of 7.3 indicates a high severity, reflecting the network attack vector (AV:N), low attack complexity (AC:L), and significant impacts on confidentiality and integrity (C:H/I:H), though availability is not affected (A:N). Exploiting this vulnerability could allow attackers to steal session tokens, perform actions on behalf of users, or conduct further attacks within the victim’s context. Although no known exploits are currently reported in the wild, the vulnerability's presence in a widely used enterprise monitoring tool makes it a significant concern. The lack of available patches at the time of reporting increases the urgency for mitigation. The vulnerability highlights the importance of secure coding practices, particularly proper input validation and output encoding in web applications that generate dynamic content.

For European organizations, this vulnerability poses a substantial risk, especially for those using ManageEngine Exchange Reporter Plus to monitor Microsoft Exchange environments. Successful exploitation could lead to unauthorized access to sensitive email metadata and reporting data, potentially exposing confidential business communications. The high confidentiality and integrity impact means attackers could hijack user sessions, manipulate report data, or escalate privileges within the affected environment. This could disrupt operational security and lead to data breaches or compliance violations under regulations such as GDPR. The requirement for low privileges and user interaction lowers the barrier for attackers, increasing the likelihood of exploitation in targeted phishing or insider threat scenarios. Organizations in sectors with critical infrastructure, finance, healthcare, and government are particularly vulnerable due to the sensitive nature of the data processed by Exchange Reporter Plus. The absence of known exploits in the wild provides a window for proactive defense, but also means attackers may develop exploits soon after disclosure. The vulnerability could also be leveraged as a foothold for lateral movement within networks, amplifying its impact.

1. Apply security patches from Zohocorp immediately once they become available to remediate the vulnerability. 2. Until patches are released, restrict access to the Public Folders report feature to trusted administrators only, minimizing exposure. 3. Implement Web Application Firewall (WAF) rules to detect and block suspicious input patterns targeting the Public Folders report interface. 4. Conduct thorough input validation and output encoding on all user-supplied data within the application, especially in dynamic web content generation. 5. Educate users and administrators about the risks of XSS and encourage cautious behavior regarding links and reports from untrusted sources. 6. Monitor logs for unusual activity related to the Public Folders report and anomalous script execution attempts. 7. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers accessing the application. 8. Regularly audit and update the ManageEngine environment and related infrastructure to reduce attack surface. 9. Consider network segmentation to isolate critical monitoring tools from general user networks. 10. Prepare incident response plans to quickly address any exploitation attempts.
