A proof-of-concept (PoC) exploit tool has been released for a critical Apache Parquet vulnerability (CVE-2025-30065), enabling attackers to identify and exploit vulnerable servers. F5 Labs researchers developed this tool after discovering that existing PoCs were unreliable or ineffective.
This tool demonstrates the practical exploitability of CVE-2025-30065 and assists administrators in assessing their systems’ security. Apache Parquet, a columnar storage format used in big data processing, is widely deployed, making this vulnerability particularly dangerous.
You Should Know:
1. Vulnerability Details
- CVE ID: CVE-2025-30065
- Severity: Critical (CVSS 9.8)
- Affected Software: Apache Parquet versions 1.0.0 through 2.1.0
- Impact: Remote Code Execution (RCE) via maliciously crafted Parquet files.
2. Detection & Mitigation
Check if your server is vulnerable:
curl -X GET http://your-server:port/parquet/version If version <= 2.1.0, patch immediately
Mitigation Steps:
1. Upgrade to Apache Parquet 2.1.1 or later:
pip install --upgrade pyarrow For Python users
2. Block unauthorized Parquet file uploads via WAF rules.
3. Scan for exploitation attempts using:
grep -r "CVE-2025-30065" /var/log/apache2/
3. Exploit Simulation (For Security Testing)
The F5 Labs PoC tool can be used ethically to test defenses:
git clone https://github.com/f5-labs/parquet-exploit cd parquet-exploit python3 exploit.py --target http://vulnerable-server:port
4. Log Analysis for Intrusion Detection
Check for suspicious activity in logs:
journalctl -u apache2 --since "1 hour ago" | grep "parquet"
5. Network Traffic Monitoring
Use `tcpdump` to detect exploit attempts:
tcpdump -i eth0 'port 80 and tcp[((tcp[12:1] & 0xf0) >> 2):4] = 0x70617271'
What Undercode Say
This vulnerability highlights the risks in widely used data processing frameworks. Organizations must:
– Patch immediately if using vulnerable versions.
– Monitor logs for exploit attempts.
– Restrict file uploads to trusted sources only.
– Use intrusion detection systems (IDS) like Suricata:
suricata -c /etc/suricata/suricata.yaml -i eth0
Expected Output:
A secure, patched Apache Parquet deployment with active monitoring to prevent exploitation.
Prediction
As more PoC tools emerge, automated attacks targeting unpatched Parquet servers will increase. Organizations delaying patches will face higher breach risks.
