CVE-2024-57704 is a high-severity Out-of-bounds Write (CWE-787) vulnerability in Tenda Ac8 Firmware. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 45.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
SI-10 requires input validation at entry points like the schedStartTime argument in /goform/openSchedWifi, directly preventing stack-based buffer overflows from malformed inputs.
SI-16 enforces memory protections such as stack canaries, ASLR, and DEP that mitigate exploitation of stack buffer overflows even if invalid input reaches the function.
SI-2 mandates timely identification and remediation of flaws like CVE-2024-57704, preventing exploitation through firmware patching.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Stack overflow in public-facing web interface (/goform/openSchedWifi) enables remote code execution via exploitation of the vulnerable router application.
NVD Description
Tenda AC8v4 V16.03.34.06 has a stack overflow vulnerability. Affected by this vulnerability is the function setSchedWifi of the file /goform/openSchedWifi. The manipulation of the argument schedStartTime leads to stack-based buffer overflow.
Deeper analysisAI
CVE-2024-57704 is a stack-based buffer overflow vulnerability (CWE-787) affecting Tenda AC8v4 router firmware version V16.03.34.06. The flaw resides in the setSchedWifi function within the /goform/openSchedWifi file, where manipulation of the schedStartTime argument triggers the overflow.
The vulnerability has a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating network accessibility with low attack complexity. Exploitation requires low privileges, such as those of an authenticated user, and no user interaction. Successful exploitation can compromise confidentiality, integrity, and availability to a high degree.
