Usually, phrasing codes are a complicated process especially if there was more codes and more cases. codes embedded into HTML tags, are more dangerous. I’m approximately sure that there is no reasonable solution but using Regular Expression for this propose. In this case, 3 other codes phrased using str_replace() function that is very weaker than preg_replace(). Look at the related code: $comment[’comment’] = preg_replace(’/\[url\](.*)\[\/url\]/si’,’$1‘,$comment[’comment’]); Even in this using of preg_replace, using a weak pattern (.*) results to a simple XSS bug. ————–Exploit———————- comment this at a desired file detail: [url]javascript:alert(1)[/url] ———–Solution——————— Not any updates available~ ————–Credit———————– Discovered by: imei addmimistrator addmimistrator(4}gmail(O}com ------------------------ End------------------ -- imei Addmimistrator Visit my SeQrity Homepage at: http://myimei.com/security
