Overview
A critical security vulnerability, identified as CVE-2025-63219, has been discovered in the ITEL ISO FM SFN Adapter. This vulnerability allows for session hijacking due to improper session management on the /home.html endpoint. Successful exploitation allows an attacker to gain complete control over the affected device.
Technical Details
The vulnerability resides in the ITEL ISO FM SFN Adapter, specifically affecting firmware version ISO2 2.0.0.0 and WebServer 2.0. The core issue is the lack of adequate session validation and management on the /home.html endpoint. This allows an unauthenticated attacker to potentially access and take over an active user session. By exploiting this flaw, an attacker can bypass authentication mechanisms, gaining unauthorized access to administrative functionalities and device configurations.
CVSS Analysis
Currently, a CVSS score is not available for CVE-2025-63219. However, given the potential for complete device takeover and the ability to modify configurations, this vulnerability should be considered critical. A formal CVSS score will be updated when available.
Possible Impact
The exploitation of CVE-2025-63219 can have severe consequences, including:
- Complete Device Control: Attackers can gain full administrative control over the ITEL ISO FM SFN Adapter.
- Configuration Modification: Unauthorized modification of device settings, potentially disrupting operations or creating backdoors.
- Compromised System Integrity: Attackers can compromise the integrity of the system, potentially leading to data breaches, service disruptions, or further exploitation of the network.
- Denial of Service: By manipulating device settings, attackers could render the device unusable.
Mitigation and Patch Steps
Currently, specific patch information is not readily available. However, the following mitigation steps are recommended:
- Contact ITEL Support: Immediately contact ITEL support at https://www.itel.it/ and inquire about a patch or firmware update to address CVE-2025-63219.
- Network Segmentation: Isolate the ITEL ISO FM SFN Adapter on a separate network segment to limit the potential impact of a successful exploit.
- Monitor Network Traffic: Implement network monitoring to detect any suspicious activity targeting the device.
- Temporary Workaround (if possible): If available, disable access to the /home.html endpoint until a patch is available (only if this does not affect critical functionality). Consult with ITEL support before attempting this.
Important: Applying the patch or mitigation steps should be done in a test environment before applying in production
