Assigner: VulDB

Description
A vulnerability was identified in Linksys RE6500, RE6250, RE6300, RE6350, RE7000 and RE9000 1.0.013.001/1.0.04.001/1.0.04.002/1.1.05.003/1.2.07.001. This affects the function AP_get_wired_clientlist_setClientsName of the file mod_form.so. The manipulation of the argument clientsname_0 leads to stack-based buffer overflow. The attack may be initiated remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.

CWE ID Description
CWE-787 The product writes data past the end, or before the beginning, of the intended buffer.
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).

Detection Guidance

This vulnerability can be detected by monitoring for unusual or malformed requests targeting the function AP_get_wired_clientlist_setClientsName, specifically those manipulating the clientsname_%d parameter with excessively long strings. Since the exploit is publicly available, network intrusion detection systems (NIDS) can be configured to look for such exploit patterns. However, no specific detection commands or signatures are provided in the available resources. [1, 2]

Mitigation Strategies

Immediate mitigation steps include discontinuing the use of affected Linksys models (RE6500, RE6250, RE6300, RE6350, RE7000, RE9000) with vulnerable firmware versions, as no patches or vendor mitigations are currently available. Consider replacing these devices with alternative products. Additionally, restrict remote access to these devices and monitor network traffic for exploit attempts. [2]

Executive Summary

This vulnerability is a stack-based buffer overflow in certain Linksys router models (RE6500, RE6250, RE6300, RE6350, RE7000, and RE9000) in specific firmware versions. It occurs in the function AP_get_wired_clientlist_setClientsName within the mod_form.so file when the argument clientsname_0 is manipulated. The vulnerability can be exploited remotely, and a public exploit is available.

Impact Analysis

Exploiting this vulnerability can lead to a stack-based buffer overflow, which may allow an attacker to execute arbitrary code remotely with limited privileges. This can compromise the affected device's confidentiality, integrity, and availability, potentially leading to unauthorized access, data theft, or disruption of network services.
