No it is not. Leviticus states that if your daughters chooses voluntary slavery(often people did this as a way to pay off debt or earn extra money) the 'master' takes on the role of the father. He would protect her and provide for her and can even arrange a marriage for her(that was how people were married back than). The man does not have a right to marry her but he can arrange a marriage for his son with her.
Later on it mentions that this woman has special divorce rights. This woman can divorce her husband if she was ever abused, neglected, or denied food clothing or medical attention. This was rare because the roman government didn't allow women to divorce but God was setting up ways within the church that allowed women to divorce when it came to their safety.
EDIT: For everybody else: This passage does not exist. Women were never sold into slavery unless they voluntarility wanted to. Women were never raped, and if they were the rapist was put to death. Women had more rights than any surounding culture and these rights continue to grow through-out the bible. God keeps on trying to give women more rights, and pretty soon Paul and Jesus are preaching equality between women and comanding the men to let them get an education. Pretty soon most of the congregation is mostly women, and women are being seen as equal.
