Backslash Powered Scanning: Hunting Unknown Vulnerability Classes

Abstract
Existing web scanners search for server-side injection vulnerabilities by throwing a canned list of technology-specific payloads at a target and looking for signatures – almost like an anti-virus. In this document, I’ll share the conception a… Continue reading Backslash Powered Scanning: Hunting Unknown Vulnerability Classes

Detecting and exploiting path-relative stylesheet import (PRSSI) vulnerabilities

Early last year Gareth Heyes unveiled a fascinating new technique for attacking web applications by exploiting path-relative stylesheet imports, and dubbed it ‘Relative Path Overwrite’. This attack tricks browsers into importing HTML pages as styl… Continue reading Detecting and exploiting path-relative stylesheet import (PRSSI) vulnerabilities
