Deserialization of Untrusted Data

Property	Value
Language	java
Severity
CWE	CWE-502: Deserialization of Untrusted Data
OWASP	A08:2017 - Insecure Deserialization
Confidence Level	Low
Impact Level	High
Likelihood Level	Low

Description

The code deserializes Java objects from an external source using ObjectInputStream without verifying the source or integrity of the data. This allows attackers to supply crafted object streams that could execute harmful code or alter application behavior.

Impact

If exploited, an attacker could remotely run arbitrary code on the server, gain unauthorized access, or compromise sensitive data. This can lead to a full system breach, data loss, or service disruption, putting both application security and user data at serious risk.
