CVE-2017-12754
HighSummary
Stack buffer overflow in httpd in Asuswrt-Merlin firmware 380.67_0RT-AC5300 and earlier for ASUS devices allows remote attackers to execute arbitrary code on the router by sending a crafted http GET request packet that includes a long delete_offline_client parameter in the url.
Risk Assessment
This vulnerability poses a serious security risk as it allows remote takeover of the router, potentially leading to further attacks on the local network.
Recommendation
It is recommended to update the router firmware to the latest version to mitigate this vulnerability and to monitor logs for potential attack attempts.
