Description

QOCA aim AI Medical Cloud Platform developed by Quanta Computer has an Arbitrary File Upload vulnerability, allowing authenticated remote attackers to upload and execute web shell backdoors, thereby enabling arbitrary code execution on the server.

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match
prevent

SI-10 requires validation of information inputs, directly preventing arbitrary file uploads by checking file content, type, and structure to block web shells.

SI-9 Information Input Restrictions good match
prevent

SI-9 restricts types, amounts, and characteristics of inputs, preventing upload of executable web shells through file type whitelisting and limits.

SI-3 Malicious Code Protection partial match
preventdetect

SI-3 provides malicious code protection to scan and quarantine uploaded web shells before execution on the server.

Security SummaryAI

CVE-2025-15240 is an Arbitrary File Upload vulnerability (CWE-434) in the QOCA aim AI Medical Cloud Platform developed by Quanta Computer. Published on 2026-01-05, it enables authenticated remote attackers to upload and execute web shell backdoors, resulting in arbitrary code execution on the server. The vulnerability 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 network accessibility, low attack complexity, and significant impacts across confidentiality, integrity, and availability.

An attacker with low-privilege authenticated access can exploit this flaw remotely over the network without requiring user interaction. By uploading malicious files such as web shells, the attacker achieves arbitrary code execution on the server, potentially leading to full system compromise, data exfiltration, or further lateral movement within the environment.
