Assigner: VulDB

Description
A flaw has been found in Linksys RE6250, RE6300, RE6350, RE6500, RE7000 and RE9000 1.0.013.001/1.0.04.001/1.0.04.002/1.1.05.003/1.2.07.001. The impacted element is the function urlFilterManageRule of the file /goform/urlFilterManageRule. Executing manipulation of the argument urlFilterRuleName/scheduleUrl/addURLFilter can lead to stack-based buffer overflow. The attack may be launched remotely. The vendor was contacted early about this disclosure but did not respond in any way.

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).

Executive Summary

CVE-2025-9362 is a stack-based buffer overflow vulnerability found in multiple Linksys range extender models. It occurs in the function urlFilterManageRule within the /goform/urlFilterManageRule endpoint. The vulnerability arises because the parameters urlFilterRuleName, scheduleUrl, and addURLFilter are not properly validated for length. An attacker can send specially crafted inputs that exceed the expected size, causing a stack overflow. This can lead to crashing the device or potentially executing arbitrary code remotely without authentication. [1, 2]

Impact Analysis

This vulnerability can impact you by allowing a remote attacker to crash your Linksys device or potentially execute arbitrary code on it. This compromises the device's confidentiality, integrity, and availability. Since the exploit can be launched remotely without authentication, it poses a significant security risk. There are currently no known patches or mitigations, so affected devices may need to be replaced to avoid exploitation. [1, 2]

Detection Guidance

Detection of this vulnerability involves monitoring for unusual or malformed requests to the /goform/urlFilterManageRule endpoint, especially those manipulating the urlFilterRuleName, scheduleUrl, or addURLFilter parameters with abnormally long input values that could trigger a stack-based buffer overflow. Specific commands are not provided in the available resources. Network intrusion detection systems (NIDS) could be configured to alert on such suspicious HTTP POST requests targeting this endpoint with oversized parameters. [1, 2]

Mitigation Strategies

Immediate mitigation steps include replacing affected Linksys range extender devices (models RE6250, RE6300, RE6350, RE6500, RE7000, and RE9000 with the specified vulnerable firmware versions) with alternative products, as no patches or vendor-provided fixes are currently available. Additionally, restricting remote access to the management interface and monitoring for exploitation attempts may reduce risk temporarily. [2]
