Microsoft: Critical GoAnywhere Flaw Used in Ransomware

⚠️ Microsoft warns that a critical deserialization vulnerability, CVE-2025-10035, in Fortra's GoAnywhere MFT License Servlet Admin Console is being actively exploited in ransomware campaigns. The flaw (CVSS 10.0) enables attackers to bypass signature verification and deserialize attacker-controlled objects, potentially resulting in command injection and remote code execution on internet-exposed instances. Customers are urged to apply Fortra's patch, harden perimeter controls and run endpoint defenses in block mode to detect and stop post-breach activity.

Microsoft Links Storm-1175 to GoAnywhere Flaw, Medusa

🔒 Microsoft attributed active exploitation of a critical Fortra GoAnywhere vulnerability (CVE-2025-10035, CVSS 10.0) to the cybercriminal group Storm-1175, which has been observed deploying Medusa ransomware. The flaw is a deserialization bug that can permit unauthenticated command injection when a forged license response signature is accepted. Fortra released fixes in GoAnywhere 7.8.4 and Sustain Release 7.6.3; organizations should apply updates immediately and hunt for indicators such as dropped RMM tools, .jsp web shells, Cloudflare tunnels and Rclone usage.
