AI-suggested
- Monitor Adobe's official channels closely for patches addressing CVE-2025-30284 and apply them immediately upon release.
- Restrict user privileges to the minimum necessary, especially limiting high-privilege accounts that can trigger deserialization processes.
- Implement strict input validation and sanitization on all data that may be deserialized, employing allowlists for expected object types.
- Use application-layer firewalls or runtime application self-protection (RASP) tools to detect and block suspicious deserialization attempts.
- Conduct regular security audits and code reviews focusing on serialization/deserialization logic.
- Educate users and administrators about the risks of social engineering that could lead to user interaction exploitation.
- Isolate ColdFusion servers in segmented network zones to limit lateral movement if compromised.
- Enable detailed logging and monitoring of deserialization events to detect anomalous behavior early.
Description
ColdFusion versions 2023.12, 2021.18, 2025.0 and earlier are affected by a Deserialization of Untrusted Data vulnerability that could result in arbitrary code execution in the context of the current user. A high-privileged attacker could leverage this vulnerability to bypass security protections and execute code. Exploitation of this issue requires user interaction and scope is changed.
