HIGHCVSS Vector
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Lifecycle Timeline
3Description
A stack-based buffer overflow vulnerability was discovered in Tenda AC18 v15.03.05.05_multi. The vulnerability exists in the guestSsid parameter of the /goform/WifiGuestSet interface. Remote attackers can exploit this vulnerability by sending oversized data to the guestSsid parameter, leading to denial of service (device crash) or potential remote code execution.
Analysis
A stack-based buffer overflow vulnerability was discovered in Tenda AC18 v15.03.05.05_multi. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available.
Technical Context
This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes. A stack-based buffer overflow vulnerability was discovered in Tenda AC18 v15.03.05.05_multi. The vulnerability exists in the guestSsid parameter of the /goform/WifiGuestSet interface. Remote attackers can exploit this vulnerability by sending oversized data to the guestSsid parameter, leading to denial of service (device crash) or potential remote code execution. Affected products include: Tenda Ac18 Firmware.
Affected Products
Tenda Ac18 Firmware.
Remediation
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate write boundaries, use memory-safe languages, enable compiler protections (ASLR, stack canaries).
