Lightweight Directory Access Protocol (LDAP) is used in Web applications to provide lookup information and enforcing authentication. Web applications may suffer from LDAP injection vulnerabilities that may lead to security breaches such as login bypass and privilege escalation. This paper proposes OCL fault injection-based detection of LDAP injection vulnerabilities. We extracted design-level information and constraints are expressed in OCL and then randomly altered to generate test cases that have the capability to uncover LDAP injection vulnerabilities. We proposed two algorithms to implement test case generation. We used an open source PHP application to evaluate this approach. The analysis shows that this approach can detect LDAP injection vulnerabilities.
