Server-Side Request Forgery (SSRF)
An issue was discovered in the Kitodo.Presentation (aka dif) extension before 2.3.2, 3.x before 3.2.3, and 3.3.x before 3.3.4 for TYPO3. A missing access check in an eID script allows an unauthenticated user to submit arbitrary URLs to this component. This results in SSRF, allowing attackers to view the content of any file or webpage the webserver has access to.
CWE-918 - Server-Side Request Forgery (SSRF)
Server-side request forgery (SSRF) is a weakness that allows an attacker to send an arbitrary request, making it appear that the request was sent by the server. This request may bypass a firewall that would normally prevent direct access to the URL. The impact of this vulnerability can vary from unauthorized access to files and sensitive information to remote code execution.
