Kitodo.presentation: Server-Side Request Forgery
CVE-2022-24980 is a high-severity server-side request forgery vulnerability in Kitodo.presentation from Kitodo, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions 2.3.2, 3.2.3, 3.3.4 as the first without the flaw, so updating Kitodo.presentation to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.2% chance of exploitation within 30 days, higher than 69% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Kitodo.presentation to 2.3.2 or 3.2.3 or 3.3.4, whichever matches your release line, or a later version.
- Read the advisory on typo3.org for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
Affected products and versions
| Vendor | Product | Affected versions | Fixed in |
|---|---|---|---|
| Kitodo | Kitodo.presentation | before 2.3.2; 3.0.0 up to, but not including, 3.2.3; 3.3.0 up to, but not including, 3.3.4 | 2.3.2, 3.2.3, 3.3.4 |
Version data comes from NVD's product matching. Confirm against the vendor advisory before deciding you are unaffected.

Official description
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.

The underlying weakness: Server-Side Request Forgery
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
How developers prevent this class of flaw
- If there is a known list of applications, IP, hostname, and/or domains to which the product is allowed to communicate, then use allowlists to ensure that outgoing requests are restricted to these known entities. The allowlists could be in the application code or possibly enforced by firewalls or network segmentation.
- If the product is expected to be able to connect to arbitrary IP addresses or domains, consider using a denylist that includes private network addresses, internal domain names, etc. The denylist could be in the application code or possibly enforced by firewalls or network segmentation.
