CVE-2025-9527 Details
Description
A vulnerability was found in Linksys E1700 1.0.0.4.003. This affects the function QoSSetup of the file /goform/QoSSetup. Performing manipulation of the argument ack_policy results in stack-based buffer overflow. The attack may be initiated remotely. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.
A stack-based buffer overflow vulnerability has been identified in the Linksys E1700 router running firmware version 1.0.0.4.003. The issue arises in the QoSSetup function of the file /goform/QoSSetup, where the ack_policy parameter is vulnerable to manipulation. This lack of input validation allows remote attackers to overwrite the stack, potentially leading to arbitrary code execution. Exploitation of this vulnerability causes the router to crash, disrupting its normal service.
