CVE-2020-5558Network attack vector

Authenticated PHP code execution via undisclosed vector

Published Mar 25, 2020 · Updated Aug 4, 2024

PHP code injection in CutePHP CuteNews 2.0.1 allows remote authenticated users to execute arbitrary PHP code on the server. JPCERT/CC and the CNA record do not disclose the affected component, input, or wrong operation that permits code injection. A valid CuteNews login is required, and successful exploitation runs attacker-supplied PHP with the web server process's privileges.
