CVSSv3: 6.6 [CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L/E:U/RL:O/RC:C] [PCI]
CVE-ID: CVE-2020-2115
CWE-ID: CWE-611 - Improper Restriction of XML External Entity Reference ('XXE')
Description
The vulnerability allows a remote user to gain access to sensitive information.
The vulnerability exists due to insufficient validation of user-supplied XML input. A remote user able to control the input files for its post-build step can pass a specially crafted XML code to the affected application and view contents of arbitrary files on the system or initiate requests to external systems.
Successful exploitation of the vulnerability may allow an attacker to view contents of arbitrary file on the server or perform network scanning of internal and external infrastructure.
Mitigation
Install updates from vendor's website.
