Cross site request forgery and Web-based applications
- Affected version/s: Server 3.7
Be aware that most web-based applications, including KnowledgeTree, may be vulnerable to cross-site-request-forgeries (CSRF). CSRF is entirely different to XSS – whereas CSRF exploits the trust a server places in a user, XSS exploits the trust a user places in the server. CSRF attacks are difficult to determine because the HTTP request containing the attack is sent by a trusted user. To reduce the risk of CSRF attacks, we strongly recommend that KnowledgeTree system administrators familiarize themselves with the issue of CSRF, and take the necessary precautions to protect their KnowledgeTree installations from such attacks.
