Technical ContextAI · show details
This vulnerability is classified as Buffer Overflow (CWE-119), which allows attackers to corrupt memory to execute arbitrary code or crash the application. A vulnerability was found in Linksys RE6250, RE6300, RE6350, RE6500, RE7000 and RE9000 up to 20250801. This affects the function remoteManagement of the file /goform/remoteManagement. The manipulation of the argument portNumber leads to stack-based buffer overflow. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way. Affected products include: Linksys Re6250 Firmware, Linksys Re6300 Firmware, Linksys Re6350 Firmware, Linksys Re7000 Firmware, Linksys Re9000 Firmware. Version information: up to 20250801..

Executive ViewAI
Organizations using A vulnerability face moderate risk from CVE-2025-8831, a buffer overflow vulnerability rated CVSS 7.4. Exploitation could allow attackers to corrupt memory, crash the application, or potentially execute arbitrary code. Proof-of-concept code is publicly available, increasing the risk of exploitation. Organizations should apply vendor updates when available and consider compensating controls in the interim.
Apply vendor patch. If immediate patching is not feasible: (1) Implement network-level access controls to limit exposure; (2) Enable enhanced monitoring and alerting; (3) Apply principle of least privilege.
