CVE-2025-7633: CWE-79 Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') in Zohocorp ManageEngine Exchange Reporter Plus
Zohocorp ManageEngine Exchange Reporter Plus versions 5723 and below are vulnerable to the Stored XSS Vulnerability in the Custom report.
AI Analysis
Technical Summary
CVE-2025-7633 is a stored Cross-Site Scripting (XSS) vulnerability classified under CWE-79, found in Zohocorp's ManageEngine Exchange Reporter Plus product, specifically in versions 5723 and earlier. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages within the Custom report feature. This flaw allows an attacker with limited privileges (PR:L) to inject malicious scripts that are stored and later executed in the context of other users who view the affected reports. The attack vector is network-based (AV:N), requiring the attacker to have some level of authenticated access and user interaction (UI:R) to trigger the exploit. The vulnerability impacts confidentiality and integrity significantly (C:H/I:H), as it can lead to session hijacking, credential theft, or unauthorized actions performed on behalf of legitimate users. Availability is not impacted (A:N). Although no known exploits are currently reported in the wild, the vulnerability's nature and the widespread use of ManageEngine Exchange Reporter Plus in enterprise environments make it a critical concern. The CVSS v3.1 score of 7.3 reflects the high impact and moderate complexity of exploitation. The vulnerability was reserved in July 2025 and published in November 2025, indicating recent discovery and disclosure. The lack of available patches at the time of reporting necessitates immediate mitigation efforts by organizations using the affected versions.
Potential Impact
For European organizations, this vulnerability poses a significant risk due to the widespread use of Microsoft Exchange and associated monitoring tools like ManageEngine Exchange Reporter Plus. Successful exploitation could lead to unauthorized access to sensitive email reporting data, session hijacking, and potential lateral movement within corporate networks. This could compromise confidential communications, disrupt business operations, and lead to data breaches subject to GDPR penalties. Sectors such as finance, healthcare, government, and critical infrastructure, which rely heavily on Exchange services and reporting, are particularly vulnerable. The stored nature of the XSS increases the risk as malicious scripts persist and affect multiple users. The requirement for limited privileges and user interaction lowers the barrier for exploitation within trusted user bases. Given the high confidentiality and integrity impact, organizations may face reputational damage and regulatory consequences if exploited.
Mitigation Recommendations
1. Apply official patches from Zohocorp immediately once they become available to address CVE-2025-7633. 2. Until patches are released, restrict access to the Custom report feature to trusted administrators only, minimizing exposure. 3. Implement strict input validation and output encoding on all user-supplied data within the reporting interface to prevent script injection. 4. Employ Web Application Firewalls (WAFs) with custom rules to detect and block XSS payloads targeting ManageEngine Exchange Reporter Plus. 5. Conduct regular security audits and penetration testing focusing on web application input handling. 6. Educate users about the risks of interacting with suspicious reports or links within the application. 7. Monitor logs for unusual activities or repeated failed attempts to inject scripts. 8. Consider network segmentation to isolate the reporting tool from broader enterprise systems to limit lateral movement in case of compromise.
