SSVC AssessmentENISA
Priority Score
Attack Technique
Insecure deserialization occurs when an application converts serialized data (a stream of bytes representing an object's state) back into a living object without proper validation.
Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
