CVE-2025-6239 is an information disclosure vulnerability classified under CWE-200 affecting Zohocorp ManageEngine Applications Manager versions 176800 and below. The flaw resides in the File/Directory monitor component, which improperly exposes sensitive information to unauthorized actors who possess limited privileges (PR:L) but do not require user interaction (UI:N). The vulnerability can be exploited remotely over the network (AV:N) without elevated attack complexity (AC:L). The impact is primarily on confidentiality (C:H), with no direct effect on integrity or availability. This means attackers can gain access to sensitive data that should be protected, potentially including configuration files, credentials, or monitored directory contents, which could facilitate further attacks or data breaches. The vulnerability was reserved in June 2025 and published in October 2025, with no known exploits in the wild at the time of reporting. The absence of a patch link suggests that a fix may be pending or not publicly disclosed yet. Organizations using ManageEngine Applications Manager for application performance monitoring and infrastructure management should be aware of this exposure risk, especially if they rely on the File/Directory monitor feature. The CVSS 3.1 base score of 6.5 reflects a medium severity rating, balancing the high confidentiality impact against the requirement for some privileges and no user interaction.

For European organizations, this vulnerability poses a risk of unauthorized disclosure of sensitive operational or configuration data managed by ManageEngine Applications Manager. Such exposure can lead to information leakage that attackers might leverage for lateral movement, privilege escalation, or targeted attacks against critical infrastructure. Industries with stringent data protection requirements, such as finance, healthcare, and government, could face compliance risks under GDPR if sensitive personal or operational data is exposed. The vulnerability could undermine trust in monitoring systems and complicate incident response efforts. While it does not directly disrupt service availability or data integrity, the confidentiality breach alone can have significant operational and reputational consequences. Organizations relying heavily on ManageEngine for monitoring complex IT environments should prioritize assessing their exposure and readiness to respond to potential exploitation attempts.

1. Monitor Zohocorp’s official channels for the release of a security patch addressing CVE-2025-6239 and apply it promptly once available. 2. Until a patch is released, restrict access to the File/Directory monitor feature to only trusted and necessary personnel by enforcing strict role-based access controls (RBAC). 3. Implement network segmentation and firewall rules to limit exposure of the ManageEngine Applications Manager interface to internal trusted networks only. 4. Conduct thorough audits of user privileges within the ManageEngine environment to ensure no unnecessary elevated access is granted. 5. Enable detailed logging and monitoring of access to the File/Directory monitor feature to detect any anomalous or unauthorized access attempts. 6. Consider deploying additional data loss prevention (DLP) measures to detect and prevent unauthorized exfiltration of sensitive information. 7. Educate IT and security teams about the vulnerability specifics to enhance detection and response capabilities.
