Security researchers have released a proof-of-concept (PoC) exploit for a critical vulnerability in Fortinet's FortiClient Enterprise Management Server (EMS) software, which is now actively exploited in attacks.
Hackers are attempting to leverage a recently fixed critical vulnerability (CVE-2023-50164) in Apache Struts that leads to remote code execution, in attacks that rely on publicly available proof-of-concept exploit code.
Proof-of-concept exploit code has been released online for two actively exploited and high-severity vulnerabilities in Microsoft Exchange, collectively known as ProxyNotShell.
