: This allowed unauthenticated attackers to read sensitive system files, such as /etc/shadow (containing password hashes) or configuration files storing the ISP's PPPoE credentials and Wi-Fi pre-shared keys. 2. Hardcoded Credentials and Hidden Backdoors

Coordinate closely with ZTE to compile, test, and push security patches aggressively to subscriber gateways as soon as zero-day disclosures emerge.

: Vulnerabilities in the web interface (often via the ping or traceroute diagnostic tools) allow attackers to bypass input validation and execute arbitrary system commands.

Automated bots continuously scan the internet for routers with exposed web interfaces and attempt to log in using default or commonly used passwords. Once inside, attackers can modify DNS settings to redirect users to malicious websites (e.g., phishing pages), enable remote management for persistent access, or add the router to a botnet for DDoS attacks.

While often considered less severe than RCE, XSS vulnerabilities in the management interface can be used to hijack a logged-in administrator’s session, allowing the attacker to change settings, alter DNS configurations, or install persistent malicious scripts. How an Exploit is Executed : This allowed unauthenticated attackers to read sensitive
