Severity:	low
Title:	phpLDAPadmin: Authentication bypass
Date:	09/06/2005
Bugs:	#104293
ID:	200509-04

Synopsis

A flaw in phpLDAPadmin may allow attackers to bypass security restrictions and connect anonymously.

Background

phpLDAPadmin is a web-based LDAP client allowing to easily manage LDAP servers.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-nds/phpldapadmin	< 0.9.7_alpha6	>= 0.9.7_alpha6	All supported architectures

Description

Alexander Gerasiov discovered a flaw in login.php preventing the application from validating whether anonymous bind has been disabled in the target LDAP server configuration.

Impact

Anonymous users can access the LDAP server, even if the "disable_anon_bind" parameter was explicitly set to avoid this.

Workaround

There is no known workaround at this time.

Resolution

All phpLDAPadmin users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-nds/phpldapadmin-0.9.7_alpha6"
