Exploitability
| CWE ID | Description |
|---|---|
| CWE-119 | The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data. |
| CWE-120 | The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer. |

AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2025-5793 is a critical buffer overflow vulnerability in the TOTOLINK EX1200T router firmware version 4.1.2cu.5232_B20210713. It occurs in the HTTP POST request handler at the /boafrm/formPortFw endpoint, specifically due to improper handling of the "service_type" parameter. The input buffer is copied to an output buffer without verifying the input size, leading to a buffer overflow. This flaw can be exploited remotely by sending a crafted HTTP POST request, potentially causing denial of service or other impacts on the device. [1, 2]
How can this vulnerability impact me? :
This vulnerability can impact you by compromising the confidentiality, integrity, and availability of the affected TOTOLINK EX1200T router. An attacker can remotely exploit the buffer overflow to cause denial of service (DoS), potentially disrupting network connectivity or device operation. Since no authentication is required, the attack can be launched easily from a remote location. The exploit is publicly available, increasing the risk of attacks. [1, 2]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by monitoring for malicious HTTP POST requests targeting the /boafrm/formPortFw endpoint with the 'service_type' parameter. Network intrusion detection systems (NIDS) or web application firewalls (WAF) can be configured to alert on unusual or oversized POST requests to this path. A simple detection command using curl to test the endpoint could be: curl -X POST http://<router-ip>/boafrm/formPortFw -d "service_type=test" -v. Additionally, inspecting logs for abnormal POST requests to /boafrm/formPortFw may help identify exploitation attempts. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include replacing the affected TOTOLINK EX1200T router firmware version 4.1.2cu.5232_B20210713 with a patched or updated version if available. Since no known countermeasures or mitigations have been identified, it is recommended to isolate the vulnerable device from untrusted networks, restrict access to the management interface, and monitor for exploitation attempts. If replacement or patching is not immediately possible, consider disabling remote management or blocking HTTP POST requests to /boafrm/formPortFw at the network perimeter. [2]
