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-2025-6824 is a critical buffer overflow vulnerability in the TOTOLINK X15 router firmware (version 1.0.0-B20230714.1105 and earlier). It occurs in the HTTP POST request handler at the /boafrm/formParentControl endpoint, where improper handling of the 'submit-url' argument allows an attacker to overflow a buffer by sending a specially crafted POST request. This can be exploited remotely without authentication. [1, 2]
How can this vulnerability impact me? :
This vulnerability can impact you by allowing remote attackers to cause a denial of service (DoS) on the affected TOTOLINK X15 router, disrupting its functionality. It compromises the confidentiality, integrity, and availability of the device, potentially allowing attackers to disrupt network operations. There are no known mitigations, and exploitation is considered easy with public proof-of-concept exploits available. [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/formParentControl and inspecting the 'submit-url' argument for unusually large or malformed input that could trigger a buffer overflow. Network intrusion detection systems (NIDS) or web application firewalls (WAF) can be configured to alert on suspicious POST requests targeting this path. As a command example, using curl to test the endpoint with a crafted payload could help detect vulnerability exposure: curl -X POST http://<router-ip>/boafrm/formParentControl -d "submit-url=<large_or_malicious_payload>". Additionally, network traffic capture tools like tcpdump or Wireshark can be used to filter and analyze POST requests to this endpoint. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include discontinuing use of the affected TOTOLINK X15 firmware version 1.0.0-B20230714.1105 or earlier, as no known countermeasures or patches are available. It is recommended to replace or upgrade the affected device to a version that is not vulnerable. Additionally, restricting remote access to the router's management interface and implementing network-level protections such as firewalls or intrusion prevention systems to block malicious POST requests targeting /boafrm/formParentControl can reduce exposure.
