CVE-2025-15620: CWE-306 Missing Authentication for Critical Function in Belden Hirschmann HiOS Switch Platform
HiOS Switch Platform versions 09.1.00 prior to 09.4.05 and 10.3.01 contains a denial-of-service vulnerability in the web interface that allows remote attackers to reboot the affected device by sending a malicious HTTP GET request to a specific endpoint. Attackers can trigger an uncontrolled reboot condition through crafted HTTP requests to cause service disruption and unavailability of the switch.
AI Analysis
Technical Summary
The Hirschmann HiOS Switch Platform versions 09.1.00 and 10.0.00 contain a CWE-306 missing authentication vulnerability in the web interface. This flaw allows unauthenticated remote attackers to reboot the affected switch devices by sending malicious HTTP GET requests to a specific endpoint. The reboot causes denial of service by making the switch unavailable until it restarts. The CVSS v3.1 base score is 8.6, reflecting network attack vector, low attack complexity, no privileges or user interaction required, and high impact on availability without affecting confidentiality or integrity.
Potential Impact
Successful exploitation results in denial of service due to an uncontrolled reboot of the switch device, causing temporary loss of network availability. There is no impact on confidentiality or integrity. The vulnerability can be triggered remotely without authentication, increasing the risk of disruption in network environments relying on affected switch versions.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official patch or workaround information is provided, users should monitor Belden's advisories for updates. Until a fix is available, restricting access to the device's web interface from untrusted networks may reduce exposure.
