PHP2Shell Won't Be the Last. Here's Where the Next One Will Show Up First.
Blog post from Snyk
PHP2Shell refers to two critical unauthenticated remote-code-execution vulnerabilities in the PHP engine that were reportedly exploited before their public disclosure and quickly followed by widespread proof-of-concept availability, illustrating how infrastructure-level flaws can affect applications even when their code and dependencies are well managed. The discussion emphasizes that organizations need both internal software inventories and outside-in visibility into internet-facing systems, since many PHP deployments and version details may not be visible through package manifests, container scans, or exposed server banners. It argues that rapid response depends on having an up-to-date attack-surface inventory before an advisory appears, deploying targeted exploit checks within hours, applying mitigations or patches, and retesting to verify fixes. The post also notes a subsequent partial bypass and contends that AI-assisted vulnerability research and exploit development are shortening the interval between discovery, patch release, and active exploitation. It presents continuous external testing, heuristic scanning, and application-context reasoning as complementary capabilities for identifying both known vulnerabilities and more complex flaws, while promoting Snyk’s API and web security products as tools for this approach.
