PHP2Shell vs. Log4j: Understanding the Risk and Exposure | Bitsight Webinar

Could PHP2Shell pose a cybersecurity risk on the scale of Log4j?

Newly disclosed critical PHP vulnerabilities are raising concerns about widespread exposure across enterprise environments and third-party supply chains. With millions of potentially affected systems and limited patching options for legacy PHP versions, security teams face a complex remediation challenge.

In this webinar, Bitsight experts break down the PHP2Shell vulnerabilities, share findings from Bitsight's global exposure research, and discuss practical steps organizations can take to assess risk, prioritize remediation, and investigate potential compromise.

WHAT YOU'LL LEARN

• How PHP2Shell compares to Log4j and why the vulnerabilities present a significant security challenge
• What Bitsight research reveals about PHP exposure across 50 million observed hosts, including more than 4.4 million running affected versions without straightforward patch options
• Why end-of-life PHP versions complicate vulnerability management
• What security teams should know about emerging exploitation activity and proof-of-concept risks
• How to identify vulnerable assets across your external attack surface and third-party ecosystem
• Strategies for patching, mitigating exposure, verifying vendor remediation, and detecting signs of compromise

Watch the full webinar to understand the potential scope of PHP2Shell and the steps your organization can take to reduce exposure.
