CVE-2026-1460: CWE-78 Improper neutralization of special elements used in an OS command ('OS command injection') in Zyxel DX3301-T0 firmware
CVE-2026-1460 is a high-severity post-authentication OS command injection vulnerability in Zyxel DX3301-T0 and EX3301-T0 firmware versions up to 5. 50(ABVY. 7. 1)C0. It affects the 'DomainName' parameter in the DHCP configuration file, allowing an authenticated administrator to execute arbitrary OS commands on the device. No official patch or remediation guidance is currently provided by Zyxel. The vulnerability requires administrator privileges and network access to exploit. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-1460) involves improper neutralization of special elements used in OS commands (CWE-78) within the 'DomainName' parameter of the DHCP configuration file in Zyxel DX3301-T0 and EX3301-T0 firmware versions up to 5.50(ABVY.7.1)C0. An attacker with administrator privileges who is authenticated on the device can inject OS commands, potentially leading to full compromise of the affected device. The CVSS v3.1 base score is 7.2, reflecting network attack vector, low attack complexity, high privileges required, no user interaction, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows an authenticated administrator to execute arbitrary OS commands on the affected device, potentially leading to full compromise including unauthorized control, data disclosure, and disruption of device functionality. The vulnerability impacts confidentiality, integrity, and availability at a high level. There are no reports of active exploitation in the wild.
Mitigation Recommendations
No official patch or remediation guidance has been published by Zyxel as of now. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict administrative access to trusted personnel only and monitor for suspicious activity related to DHCP configuration changes. Avoid exposing management interfaces to untrusted networks.
