Like CVE-2020-6868, has been released for CVE-2022-23136. The vulnerability is classified as "problematic" rather than critical due to its medium severity rating.
ZTE F680 V9.0.10P1N6 has an input validation vulnerability in the PON terminal product, particularly in the functionality that supports the creation of WAN connections through the web management pages.
The most critical vulnerabilities associated with the ZTE F680 family generally fall into three categories:
Ensure your ISP has pushed the latest firmware to your F680.
The ZTE F680 exploits highlight a significant problem in the telecommunications industry: the "set-it-and-forget-it" nature of CPE. Because ISPs manage these devices, users are often unable to update the firmware themselves. If an ISP fails to push a patch, the device remains vulnerable for years. This creates a massive, homogeneous attack surface where a single exploit can be used to target hundreds of thousands of households simultaneously. Conclusion zte f680 exploit
: Insufficient sanitization of user-supplied data allows remote attackers to inject and execute arbitrary HTML or script code in a user’s browser. This can lead to session hijacking or sensitive information theft.

, which are frequently targeted by IoT botnets like Mirai to gain administrative control. Remote Code Execution (RCE):
: Recent research (2024) identified a stack-based buffer overflow in the check_data_integrity function of the binary across multiple ZTE routers. : An unauthenticated attacker can exploit this to achieve RCE as root
Warning: exploiting, distributing, or using vulnerabilities against devices you do not own or do not have explicit permission to test is illegal and unethical. This article focuses on technical analysis, responsible disclosure context, and defensive mitigations.

Periodically verify that your router’s DNS settings point to trusted providers (like Google DNS, Cloudflare, or your ISP's official servers) rather than unrecognized IP addresses. For Internet Service Providers (ISPs):
Ensure management capabilities are restricted purely to the (local network). Change Default Credentials Immediately
