TrentaHost Reviewed by TrentaHost on . WHMCS newest security threat WHMCS has identified an exploit in modules/gateways/boleto. Recommended to remove the boleto folder completely if you don't use it. Posting here because I haven't seen mention of it.....if it's been mentioned elsewhere or if this is in the wrong category then mods, please move or remove. Rating: 5
