CVE-2025-3702 is a Missing Authorization vulnerability (CWE-862) identified in the Melapress File Monitor product prior to version 2.2.0. This vulnerability arises due to incorrectly configured access control security levels, allowing users with limited privileges (requiring some level of authentication but not full administrative rights) to perform unauthorized actions that should be restricted. Specifically, the vulnerability does not impact confidentiality but can lead to integrity and availability issues. An attacker with low privileges can exploit this flaw remotely (network vector) without user interaction, potentially modifying or disrupting file monitoring operations managed by Melapress File Monitor. The CVSS 3.1 base score is 5.4 (medium severity), reflecting the moderate impact and relatively low complexity of exploitation. No known exploits are currently reported in the wild, and no patches have been linked yet, indicating that the vendor may still be working on a fix or that the vulnerability is newly disclosed. The vulnerability affects all versions before 2.2.0, but the exact affected versions are not specified. The core issue is that the product fails to enforce proper authorization checks on certain functions, allowing privilege escalation within the scope of authenticated users.

For European organizations using Melapress File Monitor, this vulnerability could lead to unauthorized modification or disruption of file monitoring processes, which are often critical for security, compliance, and operational integrity. The integrity of monitored files could be compromised, potentially allowing attackers to hide malicious changes or disrupt detection mechanisms. Availability could also be affected if attackers exploit the flaw to disable or interfere with monitoring services. This could have downstream effects on incident detection and response capabilities. Since the vulnerability requires at least some level of authentication, the risk is somewhat mitigated by existing access controls; however, insider threats or compromised low-privilege accounts could leverage this vulnerability. Organizations in sectors with strict regulatory requirements for file integrity monitoring, such as finance, healthcare, and critical infrastructure, may face compliance risks if this vulnerability is exploited. The lack of known exploits currently reduces immediate risk, but the absence of patches means organizations must proactively manage exposure.

European organizations should immediately audit their use of Melapress File Monitor and identify any instances running versions prior to 2.2.0. Until a patch is released, organizations should implement compensating controls such as restricting access to the Melapress File Monitor interface to only highly trusted users and network segments, employing network segmentation and firewall rules to limit exposure. Monitoring and logging of all user activities related to the file monitor should be enhanced to detect any unauthorized attempts or suspicious behavior. Additionally, organizations should enforce strong authentication and account management policies to reduce the risk of compromised low-privilege accounts being used to exploit this vulnerability. Regularly reviewing user privileges and applying the principle of least privilege will further reduce attack surface. Once a vendor patch is available, organizations must prioritize timely deployment. Finally, consider alternative file monitoring solutions with robust authorization controls if immediate patching is not feasible.
