A critical auth-bypass flaw has been discovered in ASUS DSL routers, allowing remote, unauthenticated attackers to access devices with ease. The vulnerability affects multiple DSL router families and has prompted ASUS to release a firmware update to address the issue. While the company recommends that customers take proactive measures to secure their networks, the discovery of this critical vulnerability serves as a reminder that home internet security is not just about protecting personal data but also about safeguarding against malicious actors who can exploit vulnerabilities in devices to gain access to networks.
The ASUS DSL router has been found to have a critical auth-bypass flaw (CVE-2025-59367) that allows remote, unauthenticated attackers to access these devices. The vulnerability affects multiple DSL router families, including the DSL-AC51, DSL-N16, and DSL-AC750 models. ASUS has released a firmware update (1.1.2.3_1010) to address the issue and urges customers to update their routers for protection. The impact of this vulnerability is significant, with potential risks including botnet attacks and exposure of sensitive information. Users are advised to keep firmware up-to-date, use strong passwords, and regularly check for security updates to mitigate the risk.
The recent discovery of a critical auth-bypass flaw (CVE-2025-59367) in ASUS DSL routers has sent shockwaves through the cybersecurity community, raising concerns about the potential for remote, unauthenticated attackers to gain access to these devices. The vulnerability, which was identified by ASUS and subsequently patched, affects multiple DSL router families, including the DSL-AC51, DSL-N16, and DSL-AC750 models.
According to ASUS's advisory, a security vulnerability has been identified in certain ASUS DSL Series Router models, which can be exploited to access unpatched devices remotely. The company has released firmware version 1.1.2.3_1010 to address the issue, urging customers to update their routers to ensure they remain protected.
The impact of this vulnerability cannot be overstated. With the rise of remote work and online activities, home internet security has become a pressing concern for many individuals and families. ASUS DSL routers are a prime target of botnets, which can compromise entire networks and expose sensitive information to unauthorized parties.
In May 2025, GreyNoise researchers warned of a new AyySSHush botnet that compromised over 9,000 ASUS routers, adding a persistent SSH backdoor. This incident highlights the importance of keeping firmware and security updates up-to-date, as well as using strong, unique passwords for Wi-Fi and router admin access.
To mitigate this risk, ASUS recommends that customers update to the latest firmware and follow best practices for securing their networks. For unsupported EOL models, users can use strong, unique passwords (10+ chars with symbols and numbers) for Wi-Fi and router admin, avoiding reuses of these credentials, and regularly checking for firmware and security updates.
The discovery of this critical vulnerability serves as a reminder that home internet security is not just about protecting personal data but also about safeguarding against malicious actors who can exploit vulnerabilities in devices to gain access to networks. As the use of smart devices and home automation systems continues to grow, it is essential to stay vigilant and take proactive measures to protect our digital lives.
In conclusion, the critical auth-bypass flaw (CVE-2025-59367) in ASUS DSL routers poses a significant threat to home internet security. By staying informed about potential vulnerabilities and taking steps to secure their networks, individuals can reduce the risk of falling victim to malicious attacks.
