CWE-287 Open this link in a new tab

Overview

github.com/go-ldap/ldap is a basic LDAP v3 functionality for the GO programming language.

Affected versions of the package are vulnerable to Access Restriction Bypass.

In the ldap.v2 (aka go-ldap) package through 2.5.0 for Go, an attacker may be able to login with an empty password. This issue affects an application using this package if these conditions are met: (1) it relies only on the return error of the Bind function call to determine whether a user is authorized (i.e., a nil return value is interpreted as successful authorization) and (2) it is used with an LDAP server allowing unauthenticated bind.

Remediation

Upgrade to commit 95ede12 from Aug 24, 2017 or newer.
