Cross-site scripting (XSS) vulnerability in KnowledgeTree Open Source 3.4 and 3.4.1 allows remote attackers to inject arbitrary web script or HTML via the login field on the login page, and other unspecified vectors.

The Debian package of knowledgetree 2.0.7 creates environment.php with world-readable permissions, which allows local users to obtain sensitive information such as the username and password for the KnowledgeTree database.

Multiple cross-site scripting (XSS) vulnerabilities in KnowledgeTree Open Source 3.0.3 and earlier allow remote attackers to inject arbitrary web script or HTML via the (1) fDocumentId parameter in view.php and the (2) fSearchableText parameter in /search/simpleSearch.php.

SQL injection vulnerability in the get_active_session function in the KTAPI_UserSession class in webservice/clienttools/services/mdownload.php in KnowledgeTree 3.7.0.2 and earlier allows remote attackers to execute arbitrary SQL commands via the u parameter, related to the getFileName function.
