How the Mentioned CVE Works:
CVE-2025-XXXX affects Apache NiFi versions 1.13.0 through 2.2.0. The vulnerability arises when MongoDB components in NiFi generate provenance events during data processing. These events inadvertently include the username and password used for MongoDB authentication. An authorized user with read access to these provenance events can extract the credentials, leading to potential unauthorized access to the MongoDB database. This issue is classified as moderate severity due to the requirement of authorized access to exploit it. The vulnerability was patched in Apache NiFi 2.3.0, which removes sensitive credentials from provenance event records.
DailyCVE Form:
Platform: Apache NiFi
Version: 1.13.0 – 2.2.0
Vulnerability: Information Disclosure
Severity: Moderate
Date: Mar 12, 2025
What Undercode Say:
Exploitation:
- Access Provenance Events: An attacker with read access to provenance events can extract MongoDB credentials.
- Extract Credentials: Use tools like `jq` or `grep` to parse provenance logs for sensitive information.
- Exploit MongoDB: Use extracted credentials to gain unauthorized access to the MongoDB instance.
Protection:
- Upgrade: Immediately upgrade to Apache NiFi 2.3.0 or later.
- Access Control: Restrict access to provenance events to only trusted users.
- Log Monitoring: Implement log monitoring to detect unauthorized access attempts.
Commands:
1. Check NiFi Version:
nifi.sh status | grep "Version"
2. Upgrade NiFi:
wget https://downloads.apache.org/nifi/2.3.0/nifi-2.3.0-bin.tar.gz tar -xzf nifi-2.3.0-bin.tar.gz
3. Search for Credentials in Logs:
grep -i "mongodb" /path/to/nifi/logs/provenance.log
Code:
1. Python Script to Detect Credentials in Logs:
import re
with open("/path/to/nifi/logs/provenance.log", "r") as file:
for line in file:
if re.search("mongodb://.:.@", line):
print("Sensitive credentials found:", line)
2. Bash Script to Restrict Log Access:
chmod 640 /path/to/nifi/logs/provenance.log chown nifi:trusted_group /path/to/nifi/logs/provenance.log
Analytics:
- Impact: Moderate risk due to authorized access requirement.
- Affected Systems: Apache NiFi instances using MongoDB components.
- Mitigation Rate: High, as upgrading to 2.3.0 resolves the issue.
- Exploit Complexity: Low, but requires prior access to provenance events.
By following these steps, organizations can effectively mitigate the risk posed by CVE-2025-XXXX and secure their Apache NiFi instances.
