Authenticated memory disclosure via MAC filter out-of-bounds read
Published Jun 7, 2023 · Updated Jan 7, 2025
Out-of-bounds read in TP-Link TL-WR940N V2/V4, TL-WR841N V8/V10, and TL-WR740N V1/V2 allows remote authenticated users to read memory. The public record identifies the /userRpm/WlanMacFilterRpm handler but does not disclose the input parameter or memory operation that reads beyond buffer bounds. Access to the router management interface and authentication are required; resulting reads can expose memory and interrupt service.
