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-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). |

AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2025-9393 is a stack-based buffer overflow vulnerability in multiple Linksys range extender models. It exists in the addStaProfile function of the /goform/addStaProfile endpoint, where several input parameters such as profile_name, Ssid, wep_key_1 through wep_key_4, wep_key_length, wep_default_key, cipher, and passphrase are not properly validated for length. An attacker can send maliciously crafted inputs to these parameters, causing a stack overflow that can crash the device or allow remote code execution. [1, 2]
How can this vulnerability impact me? :
This vulnerability can severely impact affected devices by allowing remote attackers to crash the device or execute arbitrary code without authentication. This compromises the confidentiality, integrity, and availability of the 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 network traffic for attempts to access the /goform/addStaProfile endpoint with unusually long or malformed parameters such as profile_name, Ssid, wep_key_1, wep_key_2, wep_key_3, wep_key_4, wep_key_length, wep_default_key, cipher, or passphrase. Commands like using curl or wget to test the endpoint with crafted inputs or inspecting logs for suspicious POST requests to /goform/addStaProfile may help. For example, using curl to send a request with oversized parameters to see if the device crashes or behaves abnormally. However, no specific detection commands are provided in the resources. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include replacing affected Linksys devices (RE6250, RE6300, RE6350, RE6500, RE7000, RE9000 with specified firmware versions) with alternative products, as no patches or vendor fixes are available. Additionally, restricting remote access to the device management interface, disabling remote management if possible, and monitoring for exploit attempts can reduce risk. Since the exploit is public and remote exploitation is possible without authentication, isolating vulnerable devices from untrusted networks is recommended. [2]
