What is CVE-2023-36354?

Several TP-Link router models have been found to contain a buffer overflow vulnerability in the /userRpm/AccessCtrlTimeSchedRpm component. This weakness allows attackers to craft specific GET requests that can lead to a Denial of Service (DoS), potentially disrupting network access and performance for legitimate users. Home and small office users of affected TP-Link devices should ensure that their firmware is up to date to mitigate the risk.
