CVE-2024-33435Public exploitNetwork attack vector

Unauthenticated command injection via SysManager ping parameter

Published Apr 29, 2024 · Updated Aug 2, 2024

Command injection in Ncast Yingshi 2007 through 2017 allows remote attackers to execute arbitrary code through its web management backend. The /classes/common/busiFacade.php endpoint sends the SysManager ping service an attacker-controlled param value containing shell metacharacters. Visitor access to /manage/IPSetup.php is sufficient, and injected commands run with the web service process privileges.
