CVE-2025-29617 is a critical vulnerability in the Piciorgros TMO-100 data modem for TETRA radio networks. The device exposes an unauthenticated TFTP service on both LAN and TETRA data networks, allowing any network-adjacent attacker to read and modify the modem's configuration. The configuration file contains sensitive information such as PPP credentials and network settings. Attackers can leverage this to alter port forwarding, disrupt modem operation, or facilitate further attacks. The issue affects software versions below 4.20, where TFTP access is unrestricted and unauthenticated.
