PHP2Shell plus Fragnesia: A dangerous new route from web server to root
Dream said attackers chained PHP2Shell with a Linux privilege flaw to breach 25 firewalls and reach internal networks in minutes.
On October 23, 2026, Chinese threat actors began exploiting PHP2Shell vulnerabilities against Palo Alto Networks firewalls, targeting two servers affiliated with the United States government.
Hackers used FOFA to identify about 19,000 firewalls, narrowing targets to 240 before compromising 24 by chaining PHP2Shell with Fragnesia, a privilege-escalation flaw enabling root access.
Cybersecurity firm Dream reported attackers executed 40 custom scripts using Claude Code and Chinese AI models DeepSeek and Kimi to facilitate the breach.
CISA ordered federal agencies to patch systems within three days as attackers tunneled into internal networks within hours, launching Active Directory campaigns.
Experts warn the window between vulnerability disclosure and exploitation is closing, as attackers scan for targets before technical details emerge, making patch management critical.
