CVE-2024-45650
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 Security Verify Directory 10.0 through 10.0.3 is vulnerable to a denial of service when sending an LDAP extended operation.
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 Security Verify Directory versions 10.0 through 10.0.3 is vulnerable to a denial of service attack via specially crafted LDAP extended operations, which can cause the directory service 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.
-
Confirm IBM Security Verify Directory is installedLocate the IBM Security Verify Directory installation on the system using standard software inventory or directory listing tools (e.g., check common installation paths or use system package management tools)Affected if The software is present on the system
-
Identify the installed versionUse the product's built-in version reporting mechanism or check version metadata files in the installation directory to determine the exact version numberAffected if The version falls within 10.0.0 through 10.0.3 inclusive
-
Verify LDAP service is enabledCheck the product configuration or running services to confirm the LDAP service is active and accepting connectionsAffected if LDAP is enabled and accessible, as the vulnerability is exploited via LDAP extended operations
-
Confirm network exposure to LDAPReview network configuration to determine if LDAP ports (typically 389 or 636) are exposed to network segments beyond trusted sourcesAffected if LDAP service is exposed to untrusted network sources, enabling external attackers to send malicious extended operations
The environment is affected if IBM Security Verify Directory versions 10.0.0 through 10.0.3 is installed with LDAP service enabled and accessible, allowing remote attackers to trigger denial of service via crafted LDAP extended operations.
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 · scopedUpgrade to IBM Security Verify Directory version 10.0.4 or later per IBM's security bulletin. As a temporary measure, restrict LDAP access to trusted sources and implement network-level rate limiting.
Security Verify Directory 10.0.4 or later (latest available 10.x release)
- 1. Identify the current installed version of IBM Security Verify Directory by checking the product console or running: dsmep -status (or consult IBM documentation for your deployment method)
- 2. Review the IBM Security Verify Directory release notes and security bulletins at https://www.ibm.com/support/pages/node/7147615 (or search IBM Security Verify Directory security bulletin)
- 3. Download and install the latest available version of Security Verify Directory (version 10.0.4 or later, as 10.0.3 is the highest vulnerable version listed)
- 4. After upgrade, verify the LDAP service is running: ldapsearch -h localhost -p 389 -D "cn=admin" -w password -b "o=ibm.com" "(objectClass=*)"
- 5. Test extended LDAP operations to confirm the service handles them without crashing
- 6. Review IBM documentation for any post-upgrade configuration steps specific to your deployment
