Exploitability
| CWE ID | Description |
|---|---|
| CWE-121 | A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). |
| 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. |

AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2025-9482 is a stack-based buffer overflow vulnerability in multiple Linksys range extender models. It occurs in the portRangeForwardAdd function when certain input parameters (ruleName, schedule, inboundFilter, TCPPorts, UDPPorts) are manipulated with data exceeding expected lengths. This causes a stack overflow, allowing remote attackers to crash the router or potentially execute arbitrary code. [1, 2]
How can this vulnerability impact me? :
This vulnerability can severely impact you by allowing remote attackers to crash your Linksys router or execute arbitrary code on it. This compromises the confidentiality, integrity, and availability of your device, potentially leading to unauthorized access, disruption of network services, or control over the device. [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 attempts to access or exploit the /goform/portRangeForwardAdd endpoint with unusually long or malformed parameters such as ruleName, schedule, inboundFilter, TCPPorts, or UDPPorts. Since the exploit is remote and publicly available, network intrusion detection systems (NIDS) can be configured to alert on suspicious HTTP POST requests targeting this endpoint with oversized payloads. Specific commands are not provided in the resources, but using tools like curl or wget to test the endpoint with crafted inputs or employing network monitoring tools to detect abnormal traffic patterns to /goform/portRangeForwardAdd may help identify exploitation attempts. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
No known countermeasures or patches are available from the vendor, as Linksys did not respond to the disclosure. The recommended immediate mitigation is to replace affected devices (Linksys RE6250, RE6300, RE6350, RE6500, RE7000, and RE9000 with specified firmware versions) with alternative products. Additionally, restricting remote access to the vulnerable devices, disabling port forwarding features if possible, and monitoring network traffic for exploitation attempts can help reduce risk until replacement is possible.
