Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

A deserialization vulnerability tracked as CVE-2025-10035 affects the License Servlet component of Fortra's GoAnywhere MFT. The flaw, also referenced under CWE-502 and CWE-77, permits an actor who supplies a validly forged license response signature to deserialize an arbitrary attacker-controlled object, which can result in command injection. The issue carries a CVSS 3.1 score of 10.0 reflecting network attack vector, low complexity, no required privileges or user interaction, and complete impact to confidentiality, integrity, and availability in a changed scope.

An unauthenticated remote attacker able to craft a properly signed license response can trigger the deserialization path over the network and execute arbitrary commands on the affected server. Successful exploitation therefore grants full control of the GoAnywhere MFT instance and any data or systems it manages.

Fortra published advisory FI-2025-012 to address the issue, and the vulnerability is listed in CISA's Known Exploited Vulnerabilities catalog, confirming that mitigation guidance and patches are available from the vendor.

The associated EPSS score currently stands at 0.6224 with a recorded peak of 0.6602, and real-world exploitation has already been observed.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover command-construction flaws before deployment.

Input validation directly stops construction of commands from untrusted data containing special elements.

Secure engineering principles include proper neutralization and safe command construction practices.

Integrity verification tools can detect malformed or tampered serialized data after the fact.

Runtime monitoring of software and data can detect anomalous command execution resulting from injection.

ID.RA-01 partial match
prevents

Identifying recorded vulnerabilities enables remediation of command-injection flaws before exploitation.

PR.PS-02 none match
prevents

PR.PS-02 addresses only post-deployment updates/patching and cannot prevent introduction of unsafe deserialization code, yet it can remediate some instances when the flaw exists in outdated libraries or components.

prevents

Secure coding standards require proper escaping and parameterization of commands, directly eliminating CWE-77.

finds

Security testing in development catches command-injection vulnerabilities before release.

prevents

Secure development life cycle mandates input validation and command construction practices that directly prevent command injection.

prevents

Application security requirements explicitly call for controls against injection flaws including command injection.

prevents

Secure architecture principles reduce the attack surface but do not prescribe the specific neutralization techniques needed.

finds

Regular scanning of third-party libraries and timely patching reduce the likelihood that unsafe deserialization vulnerabilities remain active.
