HCL AION CVE-2025-62308

Exploitation requires all of the following: (1) adjacent network access to the HCL AION system (not remote internet access), (2) valid low-privilege credentials on the HCL AION instance or application, (3) user interaction-likely clicking a link, submitting a form, or navigating a specific page that triggers the disclosure, (4) high complexity, suggesting the attack is not a simple URL parameter manipulation but requires specific setup or knowledge of the vulnerable feature. The vulnerability is NOT exploitable by anonymous unauthenticated users (PR:L) or across the internet (AV:A). Default configurations of HCL AION appear vulnerable, as no configuration-specific conditions are documented; however, air-gapped deployments or those with strict network segmentation to adjacent-only trusted subnets significantly reduce real-world risk.

Real-world risk is moderate and primarily reconnaissance-focused, not immediately critical. The CVSS score of 5.1 reflects a medium-severity issue, but the attack vector profile significantly constrains widespread exploitation: AV:A (adjacent network only) eliminates remote internet-scale attacks; AC:H (high complexity) suggests non-trivial exploitation setup; PR:L (requires low privilege) and UI:R (requires user interaction) further narrow the threat actor pool to insider threats, compromised local accounts, or socially engineered employees. The confidentiality impact is low (C:L), meaning leaked information is partial, not complete backend source code or keys. However, the scope change (S:C) indicates cascading risk-exposed architecture details could inform attacks on dependent systems. The CVSS vector and description do not align with a zero-day narrative; this appears to be a logic flaw discovered during security review. Absence from CISA's Known Exploited Vulnerabilities (KEV) catalog and lack of public POC suggest limited real-world exploitation incentive to date. For defenders, this is a 'fix when convenient' issue unless HCL AION is internet-exposed or runs in highly sensitive environments (financial, healthcare, critical infrastructure) where architecture reconnaissance is a primary adversary objective.

An insider with low-privilege credentials on the HCL AION network (or an attacker who has compromised a low-privilege account via phishing) interacts with a specific HCL AION feature or interface-likely a dashboard, API endpoint, or configuration panel-that inadvertently exposes backend system details such as internal service URLs, database hostnames, or infrastructure IP ranges. This exposed information is then used to map the target's IT infrastructure, identify secondary systems to attack, or craft more sophisticated phishing messages referencing internal architecture details to lower organizational defenses.
