An html injection vulnerability has been discovered in the TP-LINK TL-WR740N router, leaving users’ systems vulnerable to potential cyber attacks. The exploit was identified by cybersecurity researcher Shujaat Amin (ZEROXINN) and reported on 25/9/2023. The affected version of the router is TP-Link TL-WR740n 3.12.11 Build 110915 Rel.40896n.
Amin outlined the steps to reproduce the vulnerability in a Proof of Concept (POC) provided with the report. By accessing the router’s IP address (192.168.0.1) and navigating to Access control –> Target,rule, users can add new rules and inject HTML code such as
into the Target Description box. Upon saving the changes, the injected HTML code will be visible on the webpage, indicating a successful exploitation of the vulnerability.
The vulnerability poses a significant security risk as it could potentially allow attackers to execute malicious code within the router’s interface, leading to unauthorized access, data theft, and further network compromise. Given that routers are the primary gateway for internet connectivity in households and businesses, the implications of such a vulnerability are grave and could result in widespread security breaches.
The vendor, TP-LINK, is urged to address the issue and release a security patch to mitigate the vulnerability and protect users from potential exploitation. In the meantime, users of the TP-LINK TL-WR740N router are advised to exercise caution and employ additional security measures to safeguard their network, such as regularly updating router firmware, implementing strong passwords, and monitoring network activity for any signs of unauthorized access.
Cybersecurity experts emphasize the importance of proactive measures to secure network devices, as vulnerabilities such as the one found in the TP-LINK TL-WR740N router can have far-reaching consequences for both individuals and organizations. As the prevalence of internet-connected devices continues to grow, the need for robust security measures to counter potential cyber threats becomes increasingly crucial.
In light of this discovery, it is crucial for both vendors and users to remain vigilant and take proactive steps to ensure the security of network devices. By promptly addressing vulnerabilities and implementing best practices for network security, the risks associated with potential cyber threats can be significantly mitigated, safeguarding users and their data from exploitation. As the cybersecurity landscape evolves, collaborative efforts between researchers, vendors, and end-users remain essential in combating emerging security challenges and fortifying the resilience of internet-connected devices.
