Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-55267 is an Unrestricted File Upload vulnerability affecting HCL Aftermarket DPC. This flaw enables an attacker to upload and execute malicious scripts, potentially gaining full control over the affected server. The vulnerability is associated with CWE-434 and has a CVSS v3.1 base score of 5.7 (AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:H/A:N), indicating network accessibility, low attack complexity, requirement for low privileges and user interaction, unchanged scope, high integrity impact, and no impact on confidentiality or availability. It was published on 2026-03-26.
An authenticated attacker with low privileges can exploit this vulnerability over the network by convincing a user to interact with a malicious upload, such as through a crafted file. Successful exploitation allows the attacker to execute arbitrary scripts on the server, leading to full control, including potential data manipulation or further compromise due to the high integrity impact.

V5.1.1
Mitigating Controls (NIST 800-53 r5) AI
Malicious-code protection at entry points blocks dangerous file types from being accepted and executed.
Least functionality restricts the file types and automatic processing capabilities the system will accept.
Mobile-code controls define, authorize, and block unacceptable uploaded code before automatic processing occurs.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Restricting execution of unauthorized software directly blocks dangerous uploaded files from running.
Hardened configuration baselines can enforce allowed file types and processing rules.
Secure development practices include input validation and file-type restrictions that prevent this weakness.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Configuration and acceptance testing verify that file-upload handling enforces allowed types and does not permit dangerous content to be stored or executed.
Secure-coding guidelines and security testing explicitly address restrictions on allowed file types and upload handling, reducing the risk that dangerous file uploads are accepted without validation.
Mandated testing for malicious content and known vulnerabilities reduces the likelihood that an outsourced component will contain or accept dangerous file types that could later be uploaded or executed.
Application allow-listing and pre-use scanning of received files directly blocks the introduction of executable content that has not been vetted, eliminating the primary vector for unrestricted dangerous file uploads.
