Summary
A vulnerability in the CGI endpoint used for configuration uploads in Draytek devices allows attackers to upload a crafted kernel module, leading to arbitrary code execution. Multiple router and VPN gateway models are affected before specific firmware versions.
Risk Assessment
The risk for the organization includes full device compromise, potentially leading to breach of network data confidentiality and integrity, and enabling further attacks on the infrastructure.
Recommendation
Immediately update the firmware of affected Draytek devices to the versions specified in the security advisory and restrict management interface access to trusted networks only.
Other vulnerabilities in Draytek
See all- CVE-2025-44643High
A vulnerability in Draytek products (AP903, AP912C, AP918R) stems from insecure configuration of the ripd.conf file, which contains a hardcoded weak password. An attacker with network access can exploit this to gain unauthorized control over the routing daemon.
- CVE-2024-41338High
A NULL pointer dereference vulnerability was found in Draytek devices. An attacker can send a crafted DHCP request, causing a Denial of Service (DoS).
