############################################################ # # Title : phpDenora <= 1.4.6 Multiple SQL Injection Vulnerabilities # # Author : P. de Brouwer - KnickLighter # @knickz0r # # NLSecurity - www.nlsecurity.org # info@nlsecurity.org # # Dork : intext:"Powered by phpDenora" # # Software : phpDenora <= 1.4.6 # http://sourceforge.net/projects/phpdenora/files/phpDenora/1.4.6/ # # Vendor : Denorastats # www.denorastats.org # # Date : 2012-02-23 # ############################################################ + -- --=[ 0x01 - Software description phpDenora is the Web Frontend to the Denora Stats Server and provides a complete, nice looking and solid Interface featu- ring detailed network, channel and user statistics, graphic- al outputs, multilanguage and template systems, all by foll- owing modern web standards. + -- --=[ 0x02 - Vulnerability description In this software, there are multiple SQL Injection vulnerab- ilities in the file "line.php". Although the variables seem to be partially filtered with the use of htmlspecialchars(), practice has proven that these parts are vulnerable. + -- --=[ 0x03 - Impact The impact of this vulnerability should be considered a high risk as attackers have the ability to manipulate the databa- se and eventually take over the machine that is running this software. + -- --=[ 0x04 - Affected versions Although there was a security release of the software on the 13th of December in 2011, there were no vulnerability detai- ls disclosed on the website of the vendor. Supposedly all v- ersions up to 1.4.6 are considered to be vulnerable as the issues have been fixed in version 1.4.7. + -- --=[ 0x05 - Vendor contact trail Contact from our side has not been made to the vendor as the issues had already been fixed in version 1.4.7 but the vend- or did not disclose the vulnerability details. + -- --=[ 0x06 - Proof of Concept (PoC) Here is a part of the code (line 74-81): // Get start date $start['year'] = isset($_GET['sy']) ? htmlspecialchars($_GET['sy']) : date('Y'); $start['month'] = isset($_GET['sm']) ? htmlspecialchars($_GET['sm']) : date('m'); $start['day'] = isset($_GET['sd']) ? htmlspecialchars($_GET['sd']) : date('d'); // Get end date $end['year'] = isset($_GET['ey']) ? htmlspecialchars($_GET['ey']) : date('Y'); $end['month'] = isset($_GET['em']) ? htmlspecialchars($_GET['em']) : date('m'); $end['day'] = isset($_GET['ed']) ? htmlspecialchars($_GET['ed']) : date('d'); The injections, according to the code start at lines 216 and 218: $sidq = sql_query("SELECT `id` FROM $table WHERE year = '".$start['year']."' AND month = '".$start['month']."' AND day = '".$start['day']."'"); $eidq = sql_query("SELECT `id` FROM $table WHERE year = '".$end['year']."' AND month = '".$end['month']."' AND day = '".$end['day']."'"); The result of the injected statements would eventually be r- eturned to the user whithin a PNG image. The file that contains the vulnerabilities is located whith- in the phpDenora folder at: /libs/phpdenora/graphs/line.php An attacker could abuse this vulnerability by performing an injection like the following: http://example.com/phpdenora/libs/phpdenora/graphs/line.php? sm=2&em=11&ey=2011&size=small&sd=6&theme=futura&lang=tr &mode=servers&sy=2011&ed=[SQLi] |
