  Title: ====== GENU CMS 2012.3 - Multiple SQL Injection Vulnerabilities     Date: ===== 2012-04-30     References: =========== http://www.vulnerability-lab.com/get_content.php?id=538     VL-ID: ===== 538     Introduction: ============= GENU is a Content Management System written with PHP language and using a database server (MySQL, PostgreSQL or SQLite) for storage. It is fully customisable since it uses a templates system and supports multiple languages.   (Copy of the Vendor Homepage: http://www.gnew.fr)     Abstract: ========= A Vulnerability Laboratory Research Team discovered multiple SQL Injection vulnerabilities in GENU CMS 2012.3 content management system.     Report-Timeline: ================ 2012-04-28: Vendor Fix/Patch by Check 2012-04-30: Public or Non-Public Disclosure     Status: ======== Published     Exploitation-Technique: ======================= Remote     Severity: ========= Critical     Details: ======== A SQL Injection vulnerabilityis detected in GENU CMS 2012.3. The vulnerability allows an attacker (remote) or local low privileged user account to inject/execute own sql commands on the affected application dbms. Successful exploitation of the vulnerability results in dbms & application compromise.   Vulnerable Module(s): [+] posts/search.php [+] news/search.php [+] comments/search.php     Proof of Concept: ================= The sql injection vulnerabilities can be exploited by remote attackers without user inter action. For demonstration or reproduce ...   Word in &apos;search&apos; must consist of at least two characters   PoC: http://127.0.0.1:8080/GENU/news/search.php?search=xd&match=<code>news_subject[SQL-Injection] http://127.0.0.1:8080/GENU/comments/search.php?search=xd&match=</code>news_subject[SQL-Injection] http://127.0.0.1:8080/GENU/posts/search.php?search=xd&match=<code>news_subject[SQL-Injection]     Solution: ========= In file: /news/search.php In line 82: AND LOWER(</code> . TABLE_NEWS . <code>.</code> . $_GET[<code>match</code>] . <code>) LIKE\</code>%<code> . strtolower($search) . </code>% <code>   In file: /comments/search.php In line 77: AND LOWER(</code> . TABLE_COMMENTS . <code>.</code> . $_GET[<code>match</code>] . <code>) LIKE</code>%<code> . strtolower($search) . </code>% <code>   In file: /posts/search.php In line 78: AND LOWER(</code> . TABLE_POSTS . <code>.</code> . $_GET[<code>match</code>] . <code>) LIKE</code>%<code> . strtolower($search) . </code>% <code> Variable $_GET[</code>match<code>] is not filtered. We must in this line</code>s edit $_GET[<code>match</code>] on $match and add code:   In file: /news/search.php In line 71   In file: /comments/search.php In line 69   In file: /posts/search.php In line 69   e.g code:   if(isset($_GET[<code>match</code>])) { if ($_GET[<code>match</code>] == <code>news_subject</code>) $match = <code>news_subject</code>; if ($_GET[<code>match</code>] == <code>news_text</code>) $match = <code>news_text</code>; else $match = <code>news_subject</code>; }     Risk: ===== The security risk of the sql injection vulnerabilities are estimated as high(+).     Credits: ======== Vulnerability Laboratory [Research Team]-snup (snup@vulnerability-lab.com)
