CVE-2021-43562
The extension fails to restrict the image download to the configured pixx.io DAM URL, resulting in SSRF.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.37%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
An issue was discovered in the pixxio (aka pixx.io integration or DAM) extension before 1.0.6 for TYPO3. The extension fails to restrict the image download to the configured pixx.io DAM URL, resulting in SSRF. As a result, an attacker can download various content from a remote location and save it to a user-controlled filename, which may result in Remote Code Execution. A TYPO3 backend user account is required to exploit this.
