Synopsis

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

2. Impact Information

Background

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

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.

3. Resolution Information

Workaround

There is no known workaround at this time.

Resolution

All phpLDAPadmin users should upgrade to the latest version:

Code Listing 3.1: Resolution

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