The vulnerability identified as CVE-2024-44558 affects the Tenda AX1806 router firmware version 1.0.0.1 and represents a critical stack overflow condition that can be exploited through the adv.iptv.stbpvid parameter within the setIptvInfo function. This issue stems from inadequate input validation and buffer management within the router's web interface handling mechanism, creating a potential pathway for remote code execution and system compromise.
The technical flaw manifests when the adv.iptv.stbpvid parameter receives excessively long input data that exceeds the allocated stack buffer space within the setIptvInfo function. This parameter is typically used to configure IPTV settings within the router's advanced network configuration interface. When an attacker sends a malformed request containing a specially crafted payload exceeding the buffer limits, the program experiences a stack overflow condition that can overwrite adjacent memory locations and potentially corrupt the program's execution flow. The vulnerability falls under CWE-121 Stack-based Buffer Overflow, which is classified as a critical weakness in software security architectures.
The operational impact of this vulnerability extends beyond simple denial of service scenarios, as it can enable attackers to execute arbitrary code on the affected device with the privileges of the web server process. This remote code execution capability allows adversaries to gain full control over the router, potentially leading to man-in-the-middle attacks, network traffic interception, or the use of the compromised device as a pivot point for attacking other systems within the local network. The vulnerability affects the router's web administration interface, making it accessible to remote attackers without requiring physical access or authentication credentials. According to ATT&CK framework, this represents a technique categorized under T1210 Exploitation of Remote Services and T1072 Software Deployment Tools, as the vulnerability allows for unauthorized software execution on the target system.
Mitigation strategies should focus on immediate firmware updates from Tenda to address the buffer overflow condition, alongside network segmentation and monitoring of traffic to and from the affected device. Network administrators should implement strict input validation on all web interface parameters and consider deploying intrusion detection systems to monitor for exploitation attempts. The vulnerability highlights the importance of proper buffer management and input validation in embedded systems, particularly those handling user-supplied data through web interfaces. Organizations should also conduct thorough security assessments of their network infrastructure to identify similar vulnerabilities in other router models or firmware versions that may be susceptible to the same class of attack. The issue demonstrates how seemingly minor configuration parameters can create significant security risks when proper input validation is not implemented in embedded network devices.
