The first thing I would recommend is that you look at the class profiles of your target programs and see if your GPA is even within the considered range. If so, then you may have a chance of getting in. One of the concerns admissions committees have with high GMAT scores and low GPAs is that the applicant is smart but will not apply themselves in class. You will need to convince them that not only are you smart but you are also willing to work hard if admitted to the program. You can demonstrate this by giving examples of success and achievement that were the result of hard work. Looking at your profile, you will also need to show that your career choices were deliberate and that there is a clear professional path. Use the optional essay in your application packet to discuss your low undergrad GPA and the factors that contributed to it. Be sure to discuss lessons learned as well.
