Service crash via unchecked POST parameter copy
Published Jul 1, 2022 · Updated Aug 3, 2024
Stack overflow in Tenda M3 firmware 1.0.0.12 allows remote attackers to crash its HTTP service through a crafted POST request. The formMasterMng handler at /goform/getMasterMng copies the POST url parameter into a stack buffer without checking its length. Network access to the management HTTP endpoint is required; the published proof of concept supplies a user=admin cookie but does not establish whether authentication is enforced.
