The course provides essential skills for PHP developers necessary to make their applications resistant to contemporary attacks through the Internet. Web vulnerabilities are discussed through PHP-based examples going beyond the OWASP top ten, tackling various injection attacks, script injections, attacks against session handling of PHP, insecure direct object references, issues with file upload, and many others. PHP-related vulnerabilities are introduced grouped into the standard vulnerability types of missing or improper input validation, incorrect error and exception handling, improper use of security features and time- and state-related problems. For this latter we discuss attacks like the open_basedir circumvention, denial-of-service through magic float or the hash table collision attack. In all cases participants will get familiar with the most important techniques and functions to be used to mitigate the enlisted risks.
Both the introduction of vulnerabilities and the configuration practices are supported by a number of hands-on exercises demonstrating the consequences of successful attacks, showing how to apply mitigation techniques and introducing the use of various extensions and tools.
