Insignary Releases Free Insignary-Chk Tool to Detect PHP2Shell and Node2Shell Exposure

PHP2Shell and Node2Shell represent critical runtime vulnerabilities in two of the most widely deployed web technologies, meaning a vast number of Linux servers and container images are potentially exposed. These flaws have been actively exploited and added to CISA's Known Exploited Vulnerabilities catalog, indicating real-world threat actors are already taking advantage of unpatched systems. The release of a free scanner by Insignary highlights that many organizations still lack adequate visibility into whether their environments are affected. This matters because undetected exposure in runtime environments can lead to full server compromise, data exfiltration, and lateral movement through containerized infrastructure.
