Elevated risk57th percentile - higher than 57% of all known CVEs
Summary
A vulnerability was determined in Tenda AC7 (version 15.03.06.44). It affects an unknown function of the file /goform/setNotUpgrade. Manipulation of the newVersion argument causes a stack-based buffer overflow. The attack can be carried out remotely, and the exploit has been publicly disclosed.
Risk Assessment
A remote attacker could exploit this vulnerability to overflow the buffer, potentially enabling code execution or causing the router to crash, threatening network security.
Recommendation
Update the Tenda AC7 firmware to the latest version if a patch is available. Restricting administrative panel access can reduce risk.
