Recently ASUS has swiftly addressed critical vulnerabilities affecting several of its router models through comprehensive software updates. The vulnerabilities, identified as CVE-2024-3080 and CVE-2024-3079, posed significant risks by potentially allowing unauthorized access and arbitrary command execution on vulnerable devices.
Understanding the Critical Flaws
The primary concern, CVE-2024-3080, stands out with a CVSS v3.1 score of 9.8, categorizing it as critical. This flaw enables remote attackers to bypass authentication protocols, effectively granting them unauthorized access to impacted ASUS routers. According to insights shared by the Taiwan Computer Emergency Response Team / Coordination Center (TWCERT/CC), this vulnerability could have serious implications if exploited by malicious actors.
Alongside CVE-2024-3080, ASUS has also addressed CVE-2024-3079, which involves a high-severity buffer overflow issue (CVSS score: 7.2). Exploiting this flaw requires administrative privileges but could allow attackers to execute arbitrary commands on the affected routers. These vulnerabilities highlight the importance of prompt updates and proactive security measures in safeguarding network infrastructure.
Impacted Router Models and Firmware Updates
The security updates released by ASUS cover a range of router models prone to these vulnerabilities. Users are urged to update their devices to the latest firmware versions to mitigate potential risks effectively. Here are the models affected and the corresponding updates:

For users with these router models, ASUS provides direct links to download the necessary updates. Detailed instructions on updating firmware can be found on ASUS’s support FAQ page, ensuring a straightforward process to enhance device security.
Additional Security Measures and Recommendations
In addition to firmware updates, ASUS advises users to strengthen their network security posture by following these recommendations:
- Password Security: Ensure strong passwords for both router access and WiFi networks. ASUS recommends passwords with more than 10 non-consecutive characters to thwart brute-force attacks.
- Network Configuration: Disable unnecessary features such as remote access from WAN, port forwarding, DDNS, VPN servers, DMZ, and port triggering if not actively used.
- Vulnerability Awareness: Stay informed about potential security risks and updates related to ASUS products by regularly checking the ASUS support portal and official communications.
Broad Impact and Continuous Improvement
Earlier this year, ASUS also addressed CVE-2024-3912, another critical vulnerability impacting certain router models. This flaw, rated with a CVSS score of 9.8, allowed remote attackers to upload arbitrary files and execute system commands on affected devices. ASUS’s proactive approach in releasing timely patches underscores its commitment to customer safety and cybersecurity excellence.
Enhancing Utility Security: Download Master Updates
Beyond router firmware updates, ASUS has rolled out a new version of Download Master, addressing multiple security issues ranging from arbitrary file uploads to XSS vulnerabilities. Users are encouraged to upgrade Download Master to version 3.1.0.114 or later to mitigate these risks effectively.
Conclusion
ASUS’s prompt response to critical vulnerabilities in its router models reflects a proactive stance in safeguarding user data and network integrity. By promptly releasing security patches and offering comprehensive guidance on updating firmware, ASUS ensures that its customers can mitigate potential cybersecurity threats effectively. Users of affected ASUS routers are strongly advised to implement these updates without delay to fortify their devices against evolving security risks. For ongoing protection, staying informed and adhering to best practices in network security remain crucial in today’s interconnected digital landscape.
