CVE-2025-52649
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedHCL AION is affected by a vulnerability where certain identifiers may be predictable in nature. Predictable identifiers may allow an attacker to infer or guess system-generated values, potentially leading to limited information disclosure or unintended access under specific conditions.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceHCL AION contains a vulnerability where certain system-generated identifiers (such as session tokens, record IDs, or object references) can be predicted or guessed by attackers due to insufficient randomness in their generation algorithm. An attacker who can infer these identifiers may access limited sensitive information or perform unauthorized actions on existing records or sessions.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify HCL AION installed versionLocate the version file, configuration, or use the product's built-in version command (typically found in the installation directory or via product documentation). Note that product versions may appear in logs, the UI, or a version info file.Affected if The installed version is 2.0.0, 2.0.1, 2.0.2, 2.0.3, 2.1.0, or 2.1.1 (any version >= 2.0.0 but < 2.1.2)
-
Determine if application uses system-generated identifiersReview application configuration and codebase for usage of session tokens, record IDs, object references, or similar identifiers. Check application logs and authentication flows for patterns in generated values.Affected if The application generates or uses session tokens, record IDs, object references, or similar identifiers that could be observable in the system
-
Assess identifier generation methodIf custom identifier generation code exists, inspect the algorithm for use of predictable sources (e.g., sequential numbers, timestamps, weak random number generators, hash of predictable data). Check whether standard cryptographic methods (UUID v4, secure random tokens) are used.Affected if Custom identifier generation uses non-cryptographic or weak random methods, or uses predictable patterns
-
Check for unusual access patternsReview access logs for repeated failed attempts to guess identifiers, or successful access to resources using guessed identifiers. Look for anomalies in session token usage or record access patterns.Affected if Evidence exists of attackers successfully predicting or accessing resources using guessed identifiers
You are affected if HCL AION version is >= 2.0.0 and < 2.1.2 and the system generates or uses session tokens, record IDs, or object references that an attacker could observe and predict.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2.1.2
Replace predictable identifier generation with cryptographically secure random values (e.g., UUIDs v4, secure random tokens) and implement proper entropy requirements for all system-generated identifiers.
2.1.2 or later
- 1. Identify the current installed version of HCL AION using the system administration console or CLI
- 2. Review release notes and security advisories available at support.hcl-software.com for version 2.1.2 to understand changes
- 3. Schedule a maintenance window for the upgrade process
- 4. Back up all critical data, configurations, and system state before proceeding
- 5. Upgrade HCL AION from the current version (>=2.0.0, <2.1.2) to version 2.1.2 or the latest stable release
- 6. After upgrade, verify that the system is operational and test that predictable identifier functionality has been addressed
- 7. Monitor system logs for any anomalies post-upgrade
