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 · unedited
Directory traversal vulnerability in the Web Administration tool in IBM Tivoli Directory Server (ITDS) before 6.1.0.74-ISS-ISDS-IF0074, 6.2.x before 6.2.0.50-ISS-ISDS-IF0050, and 6.3.x before 6.3.0.43-ISS-ISDS-IF0043 and IBM Security Directory Server (ISDS) before 6.3.1.18-ISS-ISDS-IF0018 and 6.4.x before 6.4.0.9-ISS-ISDS-IF0009 allows remote attackers to read arbitrary files via a ..

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 · high confidence

Directory traversal vulnerability in the Web Administration tool of IBM Tivoli Directory Server (ITDS) and IBM Security Directory Server (ISDS) allows remote attackers to read arbitrary files on the system by using '..' (dot-dot) sequences in URLs. This is a high-severity (CVSS 7.5) issue enabling unauthenticated file disclosure.

MitigationApply the appropriate IBM interim fix (IF) for the specific version: ITDS 6.1.0.74-IF0074, 6.2.0.50-IF0050, 6.3.0.43-IF0043, or ISDS 6.3.1.18-IF0018, 6.4.0.9-IF0009. If patching is not immediately possible, consider restricting network access to the Web Administration interface via firewall or ACLs.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the installed IBM directory server product
    Locate the installed product name and version. This can typically be found in the IBM installation directory, or by querying the product via command line (for example, using 'idsversion' or checking the installation logs). Compare the result to the affected product list: IBM Tivoli Directory Server (ITDS) 6.2.0.x or IBM Security Directory Server (ISDS) 6.3.1.x or 6.4.0.x.
    Affected if The installed product is ITDS version 6.2.0, 6.2.0.0 through 6.2.0.11, or ISDS version 6.3.1, 6.3.1.0 through 6.3.1.1, or ISDS version 6.4.0, 6.4.0.0 through 6.4.0.8.
  2. Confirm the exact version number
    Retrieve the precise installed version number (for example, 6.2.0.5 or 6.4.0.4). Check the version against the specific affected versions listed: ITDS = 6.2.0, 6.2.0.0, 6.2.0.1, 6.2.0.2, 6.2.0.3, 6.2.0.4, 6.2.0.5, 6.2.0.6, 6.2.0.7, 6.2.0.8, 6.2.0.10, 6.2.0.11; ISDS = 6.4.0, 6.4.0.0, 6.4.0.1, 6.4.0.2, 6.4.0.3, 6.4.0.4, 6.4.0.5, 6.4.0.6, 6.4.0.7, 6.4.0.8, 6.3.1, 6.3.1.0.
    Affected if The exact version matches one of the versions listed in the affected versions list.
  3. Verify if the Web Administration interface is enabled
    Check whether the Web Administration tool (web-based admin console) is currently enabled and accessible on the system. This is typically configured in the IBM Directory Server configuration files or through the administration daemon status. The vulnerability exists in the Web Administration component specifically.
    Affected if The Web Administration interface is enabled and network-accessible.
  4. Check network exposure of the admin interface
    Determine if the Web Administration port (default HTTP port 9080 or HTTPS port 9443 for IBM ITDS/ISDS) is exposed to the network or internet. Review firewall rules, bind addresses in configuration, and any ACL settings controlling access to the admin URLs.
    Affected if The Web Administration interface is reachable from untrusted network segments or the internet.

The system is affected if it runs any of the listed affected versions of IBM Tivoli Directory Server or IBM Security Directory Server AND has the Web Administration interface enabled and accessible, allowing an unauthenticated remote attacker to exploit the directory traversal flaw via specially crafted URLs containing '..' sequences.

Mitigation

Apply the appropriate IBM interim fix (IF) for the specific version: ITDS 6.1.0.74-IF0074, 6.2.0.50-IF0050, 6.3.0.43-IF0043, or ISDS 6.3.1.18-IF0018, 6.4.0.9-IF0009. If patching is not immediately possible, consider restricting network access to the Web Administration interface via firewall or ACLs.
