Apache InLong, Deserialization of Untrusted Data, CVE-2025-XXXX (Moderate)

Listen to this Post

How the CVE Works

The vulnerability (CVE-2025-XXXX) in Apache InLong (versions 1.13.0 to 2.1.0) stems from insecure deserialization of user-supplied data. An authenticated attacker can manipulate serialized objects to execute arbitrary code or read sensitive files by exploiting improper validation during parameter processing. The flaw occurs when untrusted data is deserialized without proper checks, leading to remote code execution (RCE) or unauthorized file access. Attackers abuse a double-write parameter flaw to bypass security controls, compromising system integrity.

DailyCVE Form

Platform: Apache InLong
Version: 1.13.0 to 2.1.0
Vulnerability: Deserialization RCE
Severity: Moderate
Date: Jun 6, 2025

Prediction: Patch expected by Jun 30, 2025

What Undercode Say:

Exploitation Commands:

1. Craft malicious payload:

import pickle
payload = pickle.dumps({"malicious": "command"})

2. Send payload via API:

curl -X POST -d "data=$(base64 -w0 payload.bin)" http://target/inlong/endpoint

Detection & Mitigation:

1. Check vulnerable versions:

grep -r "inlong.version" /opt/inlong/

2. Apply patch immediately:

wget https://archive.apache.org/dist/inlong/2.1.0/ -O inlong-patch.tar.gz

3. Disable risky endpoints:

<!-- inlong-config.xml -->
<disable-deserialization>true</disable-deserialization>

Log Analysis:

grep "DeserializationError" /var/log/inlong/error.log

Workaround:

// Validate input before deserialization
if (!input.matches("^[a-zA-Z0-9]+$")) {
throw new SecurityException("Invalid input");
}

IDS Rule (Snort):

alert tcp any any -> $HOME_NET 8080 (msg:"Apache InLong Deserialization Attempt"; content:"|AC ED 00 05|"; sid:1000001;)

Post-Exploit Cleanup:

kill -9 $(lsof -t -i:8080) && rm -rf /tmp/malicious_

Verification:

openssl s_client -connect target:8080 | grep "InLong 2.1.0"
