- Triggered by sending crafted data.
- Risk of complete system compromise.
Live Threat
Current exploitation, exposure, and threat context
Unauthenticated PHP Object Injection in Abelle could allow an attacker to execute arbitrary code and potentially take control of a web server. This could occur when the application processes serialized data from an untrusted source, leading to a compromise of the server's integrity and confidentiality.
- Server-side code execution.
- Untrusted serialized data processing.
- Full server compromise.
Operational Fix
Recommended remediation, mitigation, and detection steps
