Acer has issued a high-priority alert for its Wave 7 mesh routers due to two critical zero-day vulnerabilities that can be exploited by unauthenticated attackers. The company urges users to update their firmware immediately after the security updates are issued.
Acer has issued a high-priority alert for Wave 7 mesh routers due to two critical zero-day vulnerabilities. The first vulnerability (CVE-2026-49200) allows unauthenticated attackers to access plaintext credentials, while the second vulnerability (CVE-2026-49201) enables remote attackers to inject backdoors into the router's system backups. Acer is working on patches for these vulnerabilities, with a planned release by end of June 2026. Users are advised to update their firmware immediately after security updates are issued and consider disabling remote management or restricting Internet access to trusted IP addresses.
Acer has issued a high-priority alert for its Wave 7 mesh routers, warning users of two critical zero-day vulnerabilities that can be exploited by unauthenticated attackers. The vulnerabilities, tracked as CVE-2026-49200 and CVE-2026-49201, were reported by security researcher Gergo Pap and affect Wave 7 routers running firmware version T7c_GBL_1.01.000055 or earlier.
The first vulnerability, CVE-2026-49200, is a broken access control flaw that allows unauthenticated attackers to remotely access plaintext credentials stored in log archives. This means that an attacker can gain unauthorized access to sensitive information, including login credentials and other sensitive data.
The second vulnerability, CVE-2026-49201, stems from a hardcoded cryptographic key that lets remote attackers without privileges gain persistent backdoor access to the router. The upload.cgi binary, responsible for processing device backups, contains this hardcoded AES encryption key. This allows an attacker to decrypt, modify, and re-encrypt system backups, facilitating persistent backdoor injection.
Acer has confirmed that it is working on patches for these two vulnerabilities, with a planned release by the end of June 2026. In the meantime, the company strongly encourages all users to update their devices' firmware immediately after the security updates are issued.
To mitigate attack risks until a patch is available, Acer customers are advised to disable remote management or, if the firmware allows, restrict Internet remote access to trusted IP addresses only. This will help prevent unauthorized access to sensitive information and reduce the risk of exploitation by unauthenticated attackers.
The discovery of these critical zero-day vulnerabilities highlights the importance of regular security updates and patches for IoT devices. As more devices become connected to the internet, the risks associated with unpatched vulnerabilities increase, making it essential for device manufacturers to prioritize security and provide timely updates to their customers.
Acer's proactive response to this issue is a testament to its commitment to protecting its customers' data and ensuring the security of its products. By urging users to update their firmware and providing guidance on how to mitigate attack risks, Acer has demonstrated its dedication to responsible disclosure and customer safety.
As the cybersecurity landscape continues to evolve, it is essential for device manufacturers, consumers, and security professionals to stay vigilant and proactive in addressing emerging threats. By working together, we can reduce the risk of exploitation by unauthenticated attackers and ensure a safer online environment for everyone.
In this article, we will delve deeper into the details of these critical zero-day vulnerabilities, explore the implications for users and device manufacturers, and discuss the steps that can be taken to mitigate attack risks until a patch is available. We will also examine Acer's response to this issue and its commitment to customer safety, as well as provide guidance on how to update firmware and protect against unauthenticated attacks.
