The CVE-2025-XXXX vulnerability in Apache Fory arises from its insecure handling of serialized objects. The library’s deserialization process does not adequately validate or restrict incoming data. A remote attacker can exploit this by sending a large, maliciously crafted serialized payload. When this payload is processed, the deserialization mechanism attempts to reconstruct complex object graphs, triggering excessive and recursive object creation. This process consumes a disproportionate amount of CPU resources, leading to complete CPU exhaustion. The system becomes unresponsive, resulting in a Denial of Service (DoS) condition that prevents legitimate users from accessing the application.
Platform: Apache Fory
Version: <0.12.2
Vulnerability: DoS
Severity: Moderate
date: 2025-09-15
Prediction: Patch 2025-09-22
What Undercode Say:
`curl -s “http://target/api” -H “Content-Type: application/java” –data-binary @malicious.ser`
`while true; do nc -v target 80 < payload.bin; done`
`jstack `
How Exploit:
Craft a serialized object with deeply nested or recursive structures to trigger high CPU usage during deserialization, causing service unavailability.
Protection from this CVE
Upgrade to Apache Fory version 0.12.2 or later. Implement network segmentation and input validation to filter serialized data from untrusted sources.
Impact:
Denial of Service (CPU exhaustion) leading to application and system unavailability.
