CVE-2024-49823
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 · uneditedIBM Common Cryptographic Architecture 7.0.0 through 7.5.51 could allow an authenticated user to cause a denial of service in the Hardware Security Module (HSM) using a specially crafted sequence of valid requests.
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 confidenceIBM Common Cryptographic Architecture versions 7.0.0 through 7.5.51 contains a denial of service vulnerability in the Hardware Security Module (HSM) where an authenticated user can trigger a DoS condition by sending a specially crafted sequence of valid requests, causing the HSM to become unavailable.

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 IBM CCA versionCheck the installed version of IBM Common Cryptographic Architecture by querying the CCA version via the system management interface, command-line tool, or HSM status command provided in the product documentation. Common methods include using the 'cca_version' or 'vsectool' command, or checking the CCA management console.Affected if The installed version is 7.0.0 through 7.5.51 (versions >= 7.0.0 and < 7.5.52)
-
Verify HSM is in useConfirm that the Hardware Security Module (HSM) functionality is enabled and actively used within the CCA environment. Check HSM status via the CCA management interface or by querying the HSM operational state using vendor-supplied diagnostic commands.Affected if HSM is enabled and accessible, as the vulnerability exists within the HSM component itself
-
Check CCA authentication configurationReview the CCA access control settings to determine whether user authentication is required for HSM operations. Examine the CCA security configuration files or management console for authentication enforcement policies.Affected if User authentication is enabled for HSM operations, as the flaw requires an authenticated user to send the malicious request sequence
-
Review HSM request loggingExamine HSM access logs and audit trails for any recent sequences of valid requests that may indicate a denial of service condition or unusual request patterns that caused HSM unavailability.Affected if Logs show recent HSM outages or unusual request patterns from authenticated users that caused the HSM to become unavailable
You are affected if your IBM CCA version is 7.0.0 through 7.5.51 and the HSM is enabled with authenticated user access.
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 · scoped7.5.52
Apply the vendor-supplied patch or upgrade to a CCA version beyond 7.5.51. Coordinate with IBM support for HSM firmware updates and implement request rate limiting or monitoring to detect abnormal request patterns.
7.5.52
- Verify current installed version of IBM Common Cryptographic Architecture
- Review IBM documentation for upgrade prerequisites and procedures
- Create a complete backup of the current HSM configuration and critical data
- Download IBM Common Cryptographic Architecture version 7.5.52 or later from IBM Fix Central or authorized distribution channels
- Follow IBM's standard upgrade procedure for CCA (typically involves stopping services, applying the update, and restarting)
- After upgrade, verify the HSM is operational and the vulnerability is resolved
