CISA KEV Advisory
Fortra GoAnywhere MFT Deserialization of Untrusted Data Vulnerability
Fortra GoAnywhere MFT contains a deserialization of untrusted data vulnerability allows an actor with a validly forged license response signature to deserialize an arbitrary actor-controlled object, possibly leading to command injection.
Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
Risk Analysis
Fortra GoAnywhere MFT is vulnerable to command injection through deserialization of untrusted data. An attacker with a forged license response signature can deserialize arbitrary objects, potentially leading to full system compromise. The high EPSS score of 0.61552 and confirmed exploitation highlight the urgency of addressing this flaw.
This vulnerability is actively exploited in the wild and is listed in CISA's KEV catalog. Exploitation requires a validly forged license response signature.
Apply the latest security patches or updates for Fortra GoAnywhere MFT. Implement input validation and secure deserialization practices where possible.
Technical Analysis
CVE-2025-10035 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2025-10035 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
