The vulnerability is caused due to the NT4 authentication component when using Access Gateway Enterprise or the NTLM authentication component when using Access Gateway Standard Edition not properly sanitising certain input before passing it as command line argument to the Samba "samedit" utility. This can be exploited to inject and execute arbitrary commands as the "root" user. The vulnerability is reported in the following products and versions: * Access Gateway 4.5 Advanced Edition * Access Gateway 4.5 Standard Edition * Access Gateway 4.6 Advanced Edition * Access Gateway 4.6 Standard Edition * Access Gateway 8.0 Enterprise Edition * Access Gateway 8.1 Enterprise Edition * Access Gateway 9.0 Enterprise Edition * Access Gateway 9.1 Enterprise Edition * Access Gateway 9.2 Enterprise Edition * Access Gateway VPX 4.6 SOLUTION: The vendor has deprecated the affected authentication methods. Migrate to a different authentication method. PROVIDED AND/OR DISCOVERED BY: George D.
