Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 26.3% of CVEs by exploit likelihood; 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). 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 prevents LFI exploitation by validating user inputs to block path traversal and arbitrary local file inclusion leading to RCE.

SI-2 Flaw Remediation good match

prevent

Mitigates the specific LFI vulnerability through timely identification, patching, and remediation of the flaw in the Organization Portal System.

AC-3 Access Enforcement partial match

prevent

Enforces logical access controls to restrict unauthorized reading of local files that could be exploited via the LFI vulnerability.

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.

NVD Description

Organization Portal System developed by WellChoose has a Local File Inclusion vulnerability, allowing unauthenticated remote attackers to execute arbitrary code on the server.

Deeper analysisAI

CVE-2025-8913 is a Local File Inclusion (LFI) vulnerability, classified under CWE-98, in the Organization Portal System developed by WellChoose. Published on 2025-08-13, it 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 critical severity due to its high impact on confidentiality, integrity, and availability. The flaw enables unauthenticated remote attackers to include local files in a way that leads to arbitrary code execution on the affected server.

Unauthenticated attackers can exploit this vulnerability over the network with low complexity and no user interaction required. Successful exploitation grants remote code execution (RCE) on the server, potentially allowing full compromise of the system, data exfiltration, or further lateral movement within the environment.
