CVE-2023-36357Network attack vector

Authenticated service interruption via unbounded GET processing

Published Jun 22, 2023 · Updated Dec 2, 2024

Denial of service in TP-Link TL-WR940N V2/V4/V6, TL-WR841N V8/V10, and TL-WR941ND V5 allows remote authenticated users to interrupt service. The /userRpm/LocalManageControlRpm endpoint processes a crafted GET request without limiting resource allocation, exhausting service resources. Valid management credentials and network access are required; the reported consequence is an availability loss with no data disclosure or modification.
