  The Semantic Web (SW) is a significant advancement in the field of Internet
technologies and an uncharted territory as far as security is concerned. In
this paper we investigate and assess the impact of known attacks of
SPARQL/SPARUL injections on Semantic Web applications developed in PHP. We
highlight future challenges of developing robust Semantic Web applications
using PHP. Our results demonstrate and quantify impacts on Confidentiality,
Integrity and Availability (CIA) breaches of data in Semantic Web applications.
Our recommendations are targeted to PHP developers, to encourage them to
integrate security as early in their design and coding practice as possible.
