CVE-2025-30065: Apache Parquet Java RCE Vulnerability

CVE-2025-30065 Overview

Schema parsing in the parquet-avro module of Apache Parquet 1.15.0 and previous versions allows bad actors to execute arbitrary code. This vulnerability is considered critical due to its potential to be exploited remotely.

Critical Impact
Remote code execution vulnerability in Apache Parquet may lead to complete system compromise.

Affected Products

Apache Parquet Java 1.15.0
Previous versions of Apache Parquet Java

Technical Details for CVE-2025-30065

Vulnerability Analysis

The vulnerability lies in how the parquet-avro module handles schema parsing. Specifically, it fails to properly sanitize input, leading to deserialization of untrusted data, which can be exploited to execute arbitrary code in the context of the application.

Root Cause

Insecure deserialization within the schema parsing mechanism of Apache Parquet's parquet-avro module.

Attack Vector

The attack can be carried out over the network, as the vulnerable component accepts serialized data without proper validation.

java

// Example exploitation code (sanitized)
ObjectInputStream in = new ObjectInputStream(maliciousInputStream);
Object o = in.readObject();

Detection Methods for CVE-2025-30065

Indicators of Compromise

Unusual outbound network traffic
Unexplained processes or services
Modifications in configuration files

Detection Strategies

Use anomaly detection systems to monitor for unusual patterns of schema parsing and serialized data input. Implement logging to capture execution flows and potential serialized data handling.

Monitoring Recommendations

Set up monitoring for incoming traffic on ports commonly exposed by Apache Parquet services and inspect serialized data for anomalies.

How to Mitigate CVE-2025-30065

Immediate Actions Required

Upgrade to Apache Parquet Java 1.15.1 immediately
Enable strict validation of all serialized data inputs
Implement network-based access control

Patch Information

More information and the patch can be found at Apache Parquet GitHub.

Workarounds

If immediate upgrade is not possible, apply input validation filters to sanitize and validate all incoming data before parsing.

bash

# Configuration example
iptables -A INPUT -p tcp --dport 80 -j DROP
