An error with LDAP authentication in Citrix Access Gateway appliances may allow an attacker to successfully authenticate without providing correct login credentials.
Citrix Access Gateway appliances use SSL VPN technology to give remote users secure access shared resources. These appliances can authenticate users through the LDAP protocol. Citrix includes LDAP authentication as part of the Advanced Access Control (AAC) options.
A unspecified vulnerability exists in Citrix Access Gateway Appliances that are using AAC version 4.2 with LDAP enabled. If successfully exploited, this vulnerability may allow an attacker to authenticate without supplying valid login credentials.
A remote attacker may be able to gain access to an internal network or shared resource.
Thanks to Citrix for information about this vulnerability.
