GHSA-g776-759r-pf6x
No affected components available
It has been discovered that the Import/Export module is susceptible to broken access control. Regular backend users have access to import functionality which usually only is available to admin users or users having User TSconfig setting options.impexp.enableImportForNonAdminUser explicitly enabled.
Database content to be imported however was correctly checked against users’ permissions and not affected. However it was possible to upload files by-passing restrictions of the file abstraction layer (FAL) - however this did not affect executable files which have been correctly secured by fileDenyPattern.
Currently the only known vulnerability is to directly inject *.form.yaml files which could be used to trigger the vulnerability of TYPO3-CORE-SA-2018-003 (privilege escalation & SQL injection) - which requires the Form Framework (ext:form) being available on an according website. CVSSv3 scoring is based on this scenario.
A valid backend user account is needed in order to exploit this vulnerability.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker needs basic access or low-level privileges. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a low impact on the integrity of the data.
Exploitation attempts have been detected. Elevated vigilance and prompt remediation are advised.
