Summary

CVE-2025-52626 is a medium-severity OS Command Injection (CWE-78) vulnerability in Hcltech Aion. Its CVSS base score is 4.5 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked at the 45th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-52626 is a potential command injection vulnerability (CWE-78) in HCL AION version 2.0. It enables unintended command execution, which could lead to unauthorized actions on the underlying system. The vulnerability received a CVSS v3.1 base score of 4.5 (AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:L) and was published on 2026-02-03.

Exploitation requires local access (AV:L), high attack complexity (AC:H), and low privileges (PR:L), with no user interaction needed (UI:N) and unchanged scope (S:U). A local low-privileged attacker could potentially inject commands to achieve low impacts on confidentiality, integrity, and availability (C:L/I:L/A:L), such as limited unauthorized system actions.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover missing or incorrect command sanitization during development.

Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.

Least privilege reduces the permissions available to any process that could be subverted by injected commands.

Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.

Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06 mostly match

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.

PR.PS-02 partial match
prevents

Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
