THREAT ACTORS HIJACK WEB TRAFFIC AFTER EXPLOITING REACT2SHELL VULNERABILITY

Summary from the TLDR InfoSec newsletter

Datadog Security Labs observed threat actors exploiting the React2Shell vulnerability (CVE-2025-55182) in React 19 server components to pivot into NGINX web servers managed via Boato Panel, deploying automated toolkits that modify configuration files to hijack web traffic. Targets predominantly include Asian organizations across .in, .id, .gov, and .edu domains, with attackers using compromised servers for traffic fingerprinting, malware delivery, and credential phishing via redirect pages. Defenders should monitor NGINX configuration file integrity, ensure React server components are patched, and audit web server access controls to detect unauthorized configuration changes.
