CVE-2025-14485 identifies a command injection vulnerability in the EFM ipTIME A3004T router firmware version 14.19.0. The flaw resides in the show_debug_screen function within the /sess-bin/timepro.cgi script, part of the Administrator Password Handler component. Attackers can manipulate the 'aaksjdkfj' parameter with crafted input containing special characters (e.g., !@dnjsrureljrm*&), leading to arbitrary command execution on the device. This vulnerability is remotely exploitable without user interaction and requires low privileges, but the attack complexity is high, indicating that exploitation demands significant skill or specific conditions. Despite the availability of a public exploit, the impact is limited due to the difficulty of exploitation and the low privileges required, reflected in the CVSS 4.0 base score of 2.3. The vendor EFM has not responded to disclosure requests, and no patches or mitigations have been officially released. The vulnerability could allow attackers to execute arbitrary commands, potentially leading to device compromise, unauthorized access, or network pivoting. However, the lack of known exploits in the wild and the high complexity reduce immediate risk. The vulnerability highlights the need for vigilance in managing embedded device firmware and monitoring for unusual activity on affected routers.

For European organizations, the impact of CVE-2025-14485 is currently low but non-negligible. If exploited, attackers could execute arbitrary commands on affected routers, potentially compromising device integrity and enabling lateral movement within internal networks. This could lead to interception or manipulation of network traffic, disruption of services, or unauthorized access to connected systems. Organizations relying on ipTIME A3004T devices for critical network infrastructure may face increased risk of targeted attacks, especially if remote management interfaces are exposed to the internet. The absence of vendor patches and public exploit availability increases the urgency for proactive defense. However, the high complexity and low privileges required limit widespread exploitation. The threat is more significant for organizations with less mature network segmentation or monitoring capabilities. Overall, while immediate widespread impact is unlikely, the vulnerability represents a foothold risk that could be leveraged in multi-stage attacks against European enterprises.

1. Immediately audit and restrict remote management access to ipTIME A3004T devices, preferably disabling remote administration unless absolutely necessary. 2. Implement strict network segmentation to isolate routers from critical internal systems, limiting potential lateral movement if compromised. 3. Monitor router logs and network traffic for unusual command execution patterns or unexpected connections originating from the device. 4. Employ intrusion detection systems (IDS) with signatures or heuristics targeting command injection attempts on router management interfaces. 5. If possible, downgrade or upgrade firmware to versions not affected by this vulnerability, or replace affected devices with models from vendors providing timely security updates. 6. Conduct internal awareness and training to ensure network administrators recognize signs of exploitation and understand the risks of exposed router management interfaces. 7. Use VPNs or secure tunnels for remote management to reduce exposure of vulnerable interfaces. 8. Regularly review and update firewall rules to block unauthorized access to router management ports. 9. Engage with EFM or reseller channels to demand security patches or mitigation guidance. 10. Maintain an inventory of all ipTIME devices in the network to ensure comprehensive coverage of mitigation efforts.
