Summary

CVE-2026-1457 is a high-severity Stack-based Buffer Overflow (CWE-121) vulnerability in Tp-Link Vigi C385 Firmware. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 29.2th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190) and 1 other technique. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly addresses the lacking input sanitization in the Web API that enables buffer overflow by validating all inputs to prevent memory corruption.

SI-2 Flaw Remediation good match

prevent

Requires timely remediation of identified flaws like this buffer handling vulnerability through firmware updates provided by the vendor.

SI-16 Memory Protection partial match

prevent

Provides memory protection mechanisms such as ASLR and DEP to mitigate exploitation of buffer overflows even if input sanitization fails.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

T1068 Exploitation for Privilege Escalation Privilege Escalation

Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.

Why these techniques?

Buffer overflow in Web API enables remote code execution from low-privileged access (T1190: Exploit Public-Facing Application) and escalation to elevated privileges (T1068: Exploitation for Privilege Escalation).

NVD Description

An authenticated buffer handling flaw in TP-Link VIGI C385 V1 Web API lacking input sanitization, may allow memory corruption leading to remote code execution. Authenticated attackers may trigger buffer overflow and potentially execute arbitrary code with elevated privileges.

Deeper analysisAI

CVE-2026-1457, published on 2026-01-29, is an authenticated buffer handling flaw classified under CWE-121 in the Web API of TP-Link VIGI C385 V1. The issue arises from insufficient input sanitization, enabling memory corruption via buffer overflow that could lead to remote code execution. It carries 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 high severity due to its potential for significant impact.

Authenticated attackers with low privileges (PR:L) can exploit the vulnerability remotely over the network (AV:N) with low attack complexity (AC:L) and without requiring user interaction (UI:N). Exploitation triggers a buffer overflow, potentially allowing arbitrary code execution with elevated privileges and resulting in high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H).

TP-Link provides mitigation through firmware updates for VIGI C385 V1, downloadable from https://www.tp-link.com/en/support/download/vigi-c385/v1/#Firmware, https://www.tp-link.com/kr/support/download/vigi-c385/v1/#Firmware, and related support resources including FAQ https://www.tp-link.com/us/support/faq/4931/.
