CVE-2025-2908 Overview
CVE-2025-2908 is a credential exposure vulnerability affecting Fermax MeetMe products in versions prior to 2024-09. The call forwarding configuration module stores credentials within configuration files that are accessible to attackers on the adjacent network. An authenticated attacker with low privileges can read these files and recover credentials that grant access to protected assets. The issue is categorized under CWE-522: Insufficiently Protected Credentials. INCIBE-CERT published the coordinated advisory covering multiple Fermax mobile application vulnerabilities.
Critical Impact
An adjacent-network attacker with low privileges can extract credentials from MeetMe call forwarding configuration files and pivot to sensitive assets.
Affected Products
- Fermax MeetMe products in versions prior to 2024-09
- Fermax mobile applications integrating the call forwarding configuration module
- Deployments exposing MeetMe configuration files on adjacent network segments

Technical Details for CVE-2025-2908
Vulnerability Analysis
The vulnerability resides in the call forwarding configuration module of Fermax MeetMe products. The module writes credentials into configuration files without adequate protection. An attacker positioned on the adjacent network can retrieve these files and extract embedded credentials. Recovered credentials then unlock downstream assets referenced by the call forwarding workflow.
The root weakness maps to CWE-522: Insufficiently Protected Credentials. Configuration files should never store secrets in clear form or with weak transformations that reverse to plaintext. The exposure directly undermines the confidentiality and integrity of connected assets.
Root Cause
The call forwarding module persists authentication material inside configuration files that lack sufficient access controls or cryptographic protection. Any actor that can read the configuration file gains the credentials in a usable form. The design does not separate configuration data from secrets or delegate credential handling to a hardened credential store.
Attack Vector
Exploitation requires adjacent network access and low-level privileges on the target environment. The attacker locates the MeetMe configuration artifacts, reads the credentials, and reuses them against the assets referenced in the call forwarding configuration. No user interaction is required. The published INCIBE-CERT advisory on Fermax mobile applications documents the affected components and coordinated fix availability.
No public proof-of-concept exploit is currently listed for CVE-2025-2908, and the vulnerability is not tracked in the CISA Known Exploited Vulnerabilities catalog.
Detection Methods for CVE-2025-2908
Indicators of Compromise
- Unauthorized reads of MeetMe call forwarding configuration files from adjacent network hosts
- Authentication events using service credentials from geographies or hosts not associated with normal MeetMe administration
- Unexpected outbound connections from MeetMe deployments to assets referenced by the call forwarding module
Detection Strategies
- Inventory all Fermax MeetMe deployments and identify instances running versions prior to 2024-09
- Audit file access telemetry for reads of configuration files belonging to the call forwarding module
- Correlate authentication logs on downstream assets with the credential set stored in MeetMe configurations to identify reuse from unexpected origins
Monitoring Recommendations
- Enable file integrity monitoring on MeetMe configuration directories and alert on read access by non-administrative principals
- Monitor adjacent network segments for reconnaissance activity targeting MeetMe management interfaces
- Rotate credentials referenced by the call forwarding module and track their usage to identify anomalous authentication events
How to Mitigate CVE-2025-2908
Immediate Actions Required
- Upgrade Fermax MeetMe products to the 2024-09 release or later as identified in the INCIBE-CERT advisory
- Rotate every credential that was configured in the call forwarding module prior to patching
- Restrict adjacent network access to MeetMe management interfaces using segmentation and firewall rules
Patch Information
Fermax addressed the credential exposure in MeetMe releases from 2024-09 onward. Administrators should consult the INCIBE-CERT advisory covering multiple Fermax mobile application vulnerabilities for the full list of affected components and remediation guidance. Apply the patched version across all endpoints and mobile clients that interact with the call forwarding workflow.
Workarounds
- Isolate MeetMe deployments on dedicated VLANs with strict access control lists limiting adjacent-network exposure
- Remove or replace credentials stored in call forwarding configurations with short-lived secrets managed by an external credential vault
- Restrict file system permissions on MeetMe configuration directories to the minimum set of service accounts required for operation
