SharePoint Zero-Day 2025: ToolPane Authentication Bypass + Deserialization RCE A brand-new, two-stage exploit is hammering SharePoint 2010-2025. OTW joins David Bombal to break down:
• How attackers bypass authentication and inject shellcode via unsafe serialization
• Why Microsoft’s May patch failed and how the “toolpane.aspx” endpoint is abused
• Live tour of a 140-line Python POC you can test in a lab
• Risk to unpatched 2010/2013 deployments (no fixes coming)
• Confirmed Chinese APT activity targeting government portals
• Immediate mitigation steps, upgrade paths, and indicator checks
• Career advice: stay ahead of AI & quantum threats by learning Linux, Python and networking
