Summary

CVE-2025-10385 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability. Its CVSS base score is 7.4 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 46.2th 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).

Deeper analysis

CVE-2025-10385 is a buffer overflow vulnerability in Mercury KM08-708H GiGA WiFi Wave2 version 1.1. The flaw affects the function sub_450B2C in the file /goform/mcr_setSysAdm, where manipulation of the ChgUserId argument triggers the overflow. It is remotely exploitable and associated with CWE-119 and CWE-120.

An attacker with low privileges can exploit this vulnerability over the network with low complexity and no user interaction, as indicated by its CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). Successful exploitation enables high-impact compromise of confidentiality, integrity, and availability, potentially allowing arbitrary code execution or denial of service on the affected device.

VulDB advisories (vuldb.com/?ctiid.323820, vuldb.com/?id.323820, vuldb.com/?submit.643902) document the issue, and a proof-of-concept exploit is publicly disclosed on GitHub (github.com/Jjx-wy/kt/blob/main/KT%20KM08-708H.md), which may facilitate active attacks. No patches or mitigations are detailed in the available references.

The exploit disclosure heightens the risk of real-world exploitation against unpatched Mercury KM08-708H GiGA WiFi Wave2 1.1 devices.

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.
Why these techniques?

Remote buffer overflow in public web form (/goform/) directly enables exploitation of a public-facing application for RCE.

Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly prevents buffer overflow exploitation by validating the ChgUserId argument in the /goform/mcr_setSysAdm endpoint using defined tools and procedures.

prevent

Requires timely identification, reporting, and correction of the buffer overflow flaw in sub_450B2C, including testing updates before deployment.

prevent

Mitigates arbitrary code execution from the buffer overflow via memory safeguards such as ASLR, DEP, and stack canaries on the affected device.
