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-2025-5787 is a critical buffer overflow vulnerability in the TOTOLINK X15 router firmware version 1.0.0-B20230714.1105. It occurs in the HTTP POST request handler at the endpoint /boafrm/formWsc, where the manipulation of the 'submit-url' argument allows an attacker to overflow a buffer by sending a specially crafted POST request. This flaw arises because the router copies input data to an output buffer without checking the input size, leading to memory corruption. The vulnerability can be exploited remotely and may cause denial of service or other disruptions to the device's normal operation. [1, 2]
How can this vulnerability impact me? :
This vulnerability can impact you by allowing a remote attacker to cause a denial of service (DoS) on the affected TOTOLINK X15 router, disrupting network connectivity and device availability. Additionally, because it affects confidentiality, integrity, and availability, it could potentially allow attackers to compromise the device's normal operation, leading to further security risks. The exploit is publicly available and requires no local access, increasing the risk of exploitation. [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 HTTP POST requests to the endpoint /boafrm/formWsc, specifically looking for suspicious or malformed requests manipulating the submit-url argument. Network intrusion detection systems (NIDS) or web application firewalls (WAF) can be configured to alert on such requests. A simple detection command using curl to test the endpoint might be: curl -X POST http://<router-ip>/boafrm/formWsc -d "submit-url=<malicious_payload>" -v. Additionally, inspecting logs for unusual POST requests to /boafrm/formWsc can help identify exploitation attempts. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include replacing the affected TOTOLINK X15 router firmware version 1.0.0-B20230714.1105 with an alternative device or firmware version not vulnerable to this issue, as no official vendor mitigations or patches are currently available. Additionally, restricting remote access to the router's web interface, disabling the vulnerable HTTP POST endpoint if possible, and implementing network-level protections such as firewalls or intrusion prevention systems to block malicious POST requests to /boafrm/formWsc can help reduce risk.
