Key Information Title RX3 V1.0br_V16.03.13.11 Stack Overflow Vulnerability Firmware Version Firmware: RX3 V1.0br_V16.03.13.11 Detailed Information Vulnerability Cause: In the function, when the parameter obtained via has a value of "shareSpeed", this value is concatenated with the -obtained parameter using , leading to a stack overflow. Similarly, due to the lack of restrictions on the parameter, a stack overflow can also occur. Code Example: Test Code: Log Information HTTPD Listening Address: 192.168.101.55 Port 80 Error Logs: Repeated occurrences of "connect: No such file or directory" and "ERROR:uwg_proc_send_msg[313] connect server is fail." Conclusion This firmware version contains a stack overflow vulnerability. By crafting a specific value for the parameter, the vulnerability can be triggered, potentially causing device crashes or exploitation by attackers.
