CVE-2011-2758
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 · uneditedIDSWebApp in the Web Administration Tool in IBM Tivoli Directory Server (TDS) 6.2 before 6.2.0.3-TIV-ITDS-IF0004 does not require authentication for access to LDAP Server log files, which allows remote attackers to obtain sensitive information via a crafted URL.
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 confidenceThe IDSWebApp in the Web Administration Tool of IBM Tivoli Directory Server 6.2 before 6.2.0.3-TIV-ITDS-IF0004 lacks authentication enforcement, allowing unauthenticated remote attackers to access LDAP Server log files via crafted URLs. This exposes potentially sensitive directory server operational details including user activity, configuration artifacts, and possibly credentials.

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 Tivoli Directory Server installation and versionRun 'idsversion' command or check the installation directory for version information. Common paths include /opt/IBM/ldap/V6.2 or the Windows equivalent.Affected if The installed version is 6.2, 6.2.0.0, 6.2.0.1, or 6.2.0.2 (before 6.2.0.3-TIV-ITDS-IF0004)
-
Determine if Web Administration Tool is enabledCheck if IDSWebApp or the Web Administration Tool service is running. Look for processes like 'idswpad' or check the configuration in the Web Administration Tool configuration files.Affected if The Web Administration Tool is installed and running on the system
-
Verify Web Administration Tool network accessibilityCheck which network interfaces the Web Administration Tool is bound to. Inspect the configuration file (typically itdsweb.cfg or similar) and check if it listens on external interfaces versus localhost only.Affected if The Web Administration Tool is bound to a reachable network interface (not restricted to localhost) and is accessible to unauthenticated users
-
Test for unauthenticated log file accessAttempt to access the log files via crafted URLs such as /idswebapp/idslog?file=../conf/idsldap.conf or similar path traversal patterns used to access LDAP server logs through the Web Administration Tool.Affected if The server returns LDAP log file contents or configuration data without requiring authentication
The environment is affected if IBM Tivoli Directory Server version 6.2, 6.2.0.0, 6.2.0.1, or 6.2.0.2 is installed with the Web Administration Tool enabled and network-accessible without authentication.

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.
From vendor dataApply vendor patch 6.2.0.3-TIV-ITDS-IF0004 to remediate. Alternatively, firewall or segment the Web Administration Tool to restrict access to authorized administrators only.
