TITLE: Andy's PHP Knowledgebase Cross-Site Scripting and Script Insertion SECUNIA ADVISORY ID: SA19554 VERIFY ADVISORY: http://secunia.com/advisories/19554/ CRITICAL: Moderately critical IMPACT: Cross Site Scripting WHERE: >From remote SOFTWARE: Andy's PHP Knowledgebase 0.x http://secunia.com/product/9225/ DESCRIPTION: Brian has discovered some vulnerabilities in Andy's PHP Knowledgebase, which can be exploited by malicious people to conduct cross-site scripting and script insertion attacks. 1) Input passed to the "keyword_list" parameter in "abk.php" isn't properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. 2) Input passed to various parameters in "submit_article.php" and "submit_question.php" isn't properly sanitised before being used. This can be exploited to inject arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious user data is viewed. The vulnerabilities have been confirmed in version 0.57. Other versions may also be affected. SOLUTION: Edit the source code to ensure that input is properly sanitised.
