Deeper analysis

CVE-2025-9475 is an unrestricted file upload vulnerability in SourceCodester Human Resource Information System 1.0. The issue affects an unknown functionality within the file /Admin_Dashboard/process/editemployee_process.php, where manipulation of the employee_file201 argument enables attackers to upload arbitrary files without restrictions.

Remote attackers can exploit this vulnerability without authentication or user interaction, as reflected in its CVSS 3.1 score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L). Exploitation may result in low impacts to confidentiality, integrity, and availability, potentially allowing file placement on the server for further compromise.

Advisories and exploit details are documented on VulDB (ctiid.321344, id.321344, submit.634745) and GitHub (lrjbsyh/CVE_Hunter issues/4 and issue-3320892747). The exploit has been publicly released, enabling immediate use by threat actors. No specific patches or mitigations are detailed in the available information.

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.
T1505.003 Web Shell Persistence
Adversaries may backdoor web servers with web shells to establish persistent access to systems.
T1608.001 Upload Malware Resource Development
Adversaries may upload malware to third-party or adversary controlled infrastructure to make it accessible during targeting.
Why these techniques?

Unrestricted file upload in public-facing web application (/Admin_Dashboard/process/editemployee_process.php) enables unauthenticated RCE via malicious PHP web shells without validation, mapping to exploitation of public-facing apps, web shell deployment/execution, and malware upload/staging.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires validation of all input (including file uploads via employee_file201) to reject malformed or dangerous content before processing.

prevent

Enforces access-control policy on the editemployee_process.php endpoint so that only permitted subjects may perform file-upload operations.

preventdetect

Deploys malicious-code protection mechanisms that scan or block uploaded files before they are stored or executed on the server.
