ASUS has released new firmware updates to address nine security vulnerabilities in its routers, including a critical authentication bypass flaw identified as CVE-2025-59366. This vulnerability affects routers with the AiCloud feature enabled, which allows remote access and personal cloud functionality. The flaw, stemming from an unintended side effect of the Samba functionality, could allow remote attackers to execute specific functions without proper authorization by chaining path traversal and OS command injection weaknesses. ASUS strongly urges all users to update their router firmware immediately to mitigate these risks.
For users with end-of-life ASUS router models that will not receive firmware updates, the company recommends disabling all internet-facing services such as AiCloud, WAN remote access, port forwarding, DDNS, VPN server, DMZ, port triggering, and FTP. Additionally, users are advised to use strong, unique passwords for both router login and WiFi to reduce exposure. The vulnerabilities have made outdated ASUS routers attractive targets for botnet campaigns, emphasizing the importance of prompt mitigation and firmware updates to protect against exploitation.

ASUS has released security advisories addressing several critical vulnerabilities affecting its routers and PC software. Notably, CVE-2025-59366 is an authentication bypass flaw in the AiCloud feature of ASUS routers, with a CVSS score of 9.4, allowing attackers to execute specific functions without proper authorization due to a Samba-related issue. Additionally, CVE-2025-12003 is a path traversal vulnerability in the WebDAV component of ASUS router firmware, enabling unauthenticated remote attackers to compromise device integrity. Another high-severity issue, CVE-2025-59373, impacts the ASUS System Control Interface Service used by the MyASUS application, allowing local privilege escalation to SYSTEM on Windows devices through a flawed file-restore mechanism. ASUS has provided patches for these vulnerabilities and urges users to update affected devices immediately. The vulnerabilities impact a wide range of ASUS products, including desktop PCs, laptops, NUC systems, All-in-One machines, and various router models. Attackers exploiting these flaws could gain unauthorized access, escalate privileges, or execute arbitrary code, posing significant risks to both home and enterprise environments. Users are advised to verify their device firmware and software versions and apply the latest security updates via Windows Update or the ASUS Support site to mitigate these threats.

ASUS has disclosed a critical authentication bypass vulnerability, tracked as CVE-2025-59367, affecting several of its DSL series router models, including DSL-AC51, DSL-N16, and DSL-AC750. This flaw allows remote, unauthenticated attackers to gain unauthorized access to unpatched devices exposed to the internet, with attacks requiring low complexity and no user interaction. ASUS has released firmware version 1.1.2.3_1010 to address the issue and strongly urges users to update their devices immediately. For users unable to update, ASUS recommends disabling all internet-accessible services such as remote WAN access, port forwarding, DDNS, VPN server, DMZ, port triggering, and FTP, as well as following best practices like using complex passwords and regularly checking for firmware updates. The vulnerability has been assigned a critical CVSS score of 9.3, highlighting the significant risk it poses to affected devices. While there are currently no reports of active exploitation, the nature of the flaw makes it a prime target for attackers seeking to compromise routers for use in botnets or DDoS attacks. Users of end-of-life models that will not receive firmware updates are especially urged to implement the recommended mitigations to reduce their exposure to potential attacks.

ASUS has released firmware and software updates for seven vulnerabilities across ASUSWRT routers and several Windows components, led by **CVE-2026-13385**, a critical router flaw rated **CVSS 9.5**. The issue affects CN SKU ASUS routers using the UU feature and, according to ASUS advisories, could let a machine-in-the-middle attacker spoof the update server and execute arbitrary commands without credentials; other reporting describes the bug as stemming from improper input validation in router management components and affecting firmware branches including `3.0.0.4_386`, `3.0.0.4_388`, and `3.0.0.6_102`. Successful exploitation could give attackers control of edge devices, enabling traffic interception, malware deployment, and broader network compromise. The broader advisory set also covers flaws in **ASUS System Control Interface v3**, **ASUS Business Manager**, **Aura Wallpaper Service**, **GameSDK**, and router web interfaces, with impacts including physical memory access, information disclosure, denial of service, unauthorized file operations, credential exposure, and data tampering. ASUS said none of the vulnerabilities are confirmed to be under active exploitation and that no public proof-of-concept is known for the critical router issue, but urged customers to apply updates immediately, disable remote administration or affected router features if patching is delayed, restrict management access to trusted IP ranges, use strong credentials, and replace end-of-life routers no longer supported after March 2026.
