CVE-2025-10035 is a critical deserialization vulnerability in the License Servlet component of Fortra GoAnywhere MFT. The flaw arises from deserialization of untrusted data during processing of a license response object. Available technical analysis indicates the vulnerable path ultimately invokes Java SignedObject deserialization on attacker-controlled content after signature verification, allowing deserialization of an arbitrary object supplied by the attacker. Successful exploitation can lead to command injection and remote code execution, potentially resulting in full system compromise. Reported affected versions include GoAnywhere MFT 7.8.x before 7.8.4 and 7.6.x before Sustain Release 7.6.3.
