CISA Confirms Active Exploitation of Two PHP2Shell Flaws Enabling Remote Code Execution

The Hacker News

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has confirmed that two recently patched vulnerabilities in PHP2Shell are being actively exploited by attackers. Both vulnerabilities are rated 9.2 on the Common Vulnerability Scoring System (CVSS) and allow unauthenticated remote code execution on affected systems. This means that attackers can potentially execute harmful code without needing to authenticate themselves. Organizations using PHP2Shell should be particularly vigilant, as the flaws could lead to severe security breaches if not addressed promptly. CISA has added these vulnerabilities to its Known Exploited Vulnerabilities (KEV) catalog, signaling the urgency for affected users to take immediate action to secure their systems.
