Acer to Patch Critical Zero-Day Vulnerabilities in Wave 7 Routers
Acer is developing a firmware update to address two severe zero-day vulnerabilities in its Wave 7 routers, disclosed by security researcher Gergo Pap. The flaws, rated with a maximum severity score under CVSS 4.0, allow unauthenticated remote exploitation and could lead to full system compromise.
The first vulnerability stems from broken access control, exposing a log file via the router’s web interface without authentication. This file contains plaintext credentials for the administrative panel and Telnet services, enabling attackers to bypass authentication entirely. The second flaw involves a hardcoded AES encryption key in the firmware, used for configuration backups. Attackers can decrypt, modify, and re-upload these backups to establish persistent backdoor access, even after reboots or credential changes.
Exploiting these vulnerabilities could grant attackers administrative control, allowing them to intercept traffic, alter DNS settings, or recruit devices into botnets. Routers exposed to the internet are especially vulnerable, as exploitation requires no prior authentication or user interaction.
Acer expects to release the patch by the end of June 2026, advising users to apply it immediately upon availability. The disclosure underscores persistent security risks in consumer networking devices, particularly around improper data handling and insecure cryptographic practices.
