Security readout for executives and security teams
Plain-English summary
HCL AION v2.0 uses shared storage without sufficient separation between product components. A process may access or alter files outside its intended scope, potentially affecting confidentiality, integrity, or availability. Exploitation is constrained by local access, high privileges, high complexity, and required user interaction.
Executive priority
Treat this as a planned remediation priority, with faster action on sensitive or multi-user systems. The moderate score and demanding prerequisites reduce urgency, but privileged cross-component file modification could undermine application trust.
Technical view
CVE-2025-52640 is a CWE-276 access-control weakness in HCL AION v2.0 shared storage. Its CVSS 3.1 score is 4.7: local attack vector, high complexity, high privileges, user interaction, changed scope, and low impact across confidentiality, integrity, and availability.
Likely exposure
Exposure is limited to identified HCL AION v2.0 deployments where product processes share storage. The supplied record lists other versions as unaffected by default, but provides no deployment-specific configuration details.
Exploitation context
The supplied sources do not report active exploitation, and the CVE is not listed as KEV in the bundle. The CVSS assessment indicates exploitation requires local access, high privileges, high complexity, and user interaction.
Researcher notes
The public bundle identifies the architectural weakness and CVSS assessment but does not provide affected configurations, patch versions, or vendor mitigation details. Testing should remain authorized and focus on access boundaries between component identities without developing weaponized procedures.
Mitigation direction
- Inventory HCL AION installations and identify systems running v2.0.
- Review the HCL advisory for vendor-approved remediation or updated-version guidance.
- Restrict shared-storage permissions to only the component identities that require access.
- Reduce unnecessary local privileged access while remediation is evaluated.
Validation and detection
- Confirm installed AION versions using authoritative asset or package records.
- Review shared-storage ownership, permissions, and access-control assignments.
- Verify each product component cannot access files outside its intended scope.
- Monitor shared storage for unexpected file access or modification activity.

Incorrect Default Permissions
Incorrect Default Permissions represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
