How to Fix CVE-2018-1000134

To remediate this vulnerability, upgrade all affected Unboundid ldapsdk dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

com.unboundid:unboundid-ldapsdk fixed: 4.0.5 
<dependency>
    <groupId>com.unboundid</groupId>
    <artifactId>unboundid-ldapsdk</artifactId>
    <version>4.0.5</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=com.unboundid

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2018-1000134, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.unboundid

Analyze the terminal output to locate any version of Unboundid ldapsdk in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.0.5), your application is affected.

Note: The mvn dependency:tree -Dincludes=com.unboundid command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-521: Weak Password Requirements, where the product does not require that users should have strong passwords. In Unboundid ldapsdk, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

UnboundID LDAP SDK version from commit 801111d8b5c732266a5dbd4b3bb0b6c7b94d7afb up to commit 8471904a02438c03965d21367890276bc25fa5a6, where the issue was reported and fixed contains an Incorrect Access Control vulnerability in process function in SimpleBindRequest class doesn't check for empty password when running in synchronous mode. The issue can result in ability to impersonate any valid user. This attack appear to be exploitable via Providing valid username and empty password against servers that do not do additional validation as per https://tools.ietf.org/html/rfc4513#section-5.1.1. This vulnerability appears to have been fixed in commit 8471904a02438c03965d21367890276bc25fa5a6.
