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). |
Attack-Flow Graph
AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2025-9363 is a stack-based buffer overflow vulnerability in multiple Linksys range extender models. It occurs in the portTriggerManageRule function when the parameters triggerRuleName or schedule are manipulated with inputs that exceed expected sizes, causing a stack overflow. This flaw allows remote attackers to crash the device or potentially execute arbitrary code due to improper input validation. [1, 2]
How can this vulnerability impact me? :
This vulnerability can impact you by compromising the confidentiality, integrity, and availability of the affected Linksys devices. An attacker can remotely exploit this flaw without local access or physical interaction, potentially crashing the device or executing arbitrary code, which could lead to device takeover or denial of service. [2]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
Detection of this vulnerability involves monitoring for attempts to exploit the portTriggerManageRule function by observing unusual or malformed requests targeting the /goform/portTriggerManageRule endpoint, specifically those manipulating the triggerRuleName or schedule parameters with abnormally long inputs. Network intrusion detection systems (NIDS) can be configured to alert on such suspicious HTTP POST requests. However, no specific detection commands or signatures are provided in the available resources. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include replacing affected Linksys devices (models RE6250, RE6300, RE6350, RE6500, RE7000, and RE9000 with vulnerable firmware versions) with alternative products, as no patches or official vendor fixes are currently available. Additionally, restricting remote access to the management interface and implementing network-level protections such as firewall rules to block access to /goform/portTriggerManageRule can reduce exposure. Monitoring for exploit attempts and isolating vulnerable devices from untrusted networks are also recommended. [2]
