Metasploit Wrap-Up 11/28/2025

This week, we have added 10 new modules to Metasploit Framework including an SMB to MSSQL relay module, a remote code execution module targeting Fortinet software, additional 32-bit and 64-bit RISC-V payloads, and more. The SMB to MSSQL NTLM relay module allows users to open MSSQL sessions and ru...

CVE-2025-63384

A vulnerability was discovered in RISC-V Rocket-Chip v1.6 and before implementation where the SRET Supervisor-mode Exception Return instruction fails to correctly transition the processor's privilege level. Instead of downgrading from Machine-mode M-mode to Supervisor-mode S-mode as specified by...
