Advanced LFI Attack Techniques - Security StackExchange

On July 30, 2012, researcher “D.W.” published a detailed analysis on Security StackExchange about advanced LFI (Local File Inclusion) attack techniques, explicitly citing Francesco “ascii” Ongaro as one of the original authors of the discovery of PHP filesystem anomalous behavior, which forms the basis of attacks known as path normalization and path truncation. The technical article credits Ongaro and the USH.it site for documenting the use of manipulated paths like /etc/passwd/. to bypass PHP filters and access restricted files. This analysis, still among the most referenced in the field today, highlights the lasting relevance of Ongaro’s research in exploit development.
