Summary

CVE-2024-57582 is a critical-severity Out-of-bounds Write (CWE-787) vulnerability in Tenda Ac18 Firmware. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 48% 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 map to SA-11 (Developer Testing and Evaluation) and SA-15 (Development Process, Standards, and Tools) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2024-57582 is a stack-based buffer overflow vulnerability (CWE-787) affecting the Tenda AC18 router running firmware version V15.03.05.19. The issue resides in the formSetPPTPServer function, where the startIP parameter triggers the overflow due to insufficient bounds checking on user-supplied input.

The vulnerability carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating it is exploitable remotely over the network with low complexity, no authentication or user interaction required. Attackers can send a specially crafted request to the affected endpoint, potentially leading to arbitrary code execution, denial of service, or full compromise of the device, granting high impacts on confidentiality, integrity, and availability.

Mitigation details and additional technical analysis are available in the referenced advisory at https://github.com/qijiale/Tenda/tree/main/9. Security practitioners should check for firmware updates from Tenda and apply network segmentation or exposure controls for affected devices until patched.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation (including fuzzing and bounds checks) finds out-of-bounds write flaws before deployment.

SA-15 Development Process, Standards, and Tools partial match

Requiring documented secure-development standards and tools can mandate bounds-checked coding practices that avoid the weakness.

SI-10 Information Input Validation partial match

Input validation can structurally reject or sanitize data that would otherwise trigger an out-of-bounds write.

SI-16 Memory Protection partial match

Memory-protection mechanisms limit the exploitability and blast radius of a successful out-of-bounds write.
