CVE-2025-13251: Datax-web SQL Injection Vulnerability

CVE-2025-13251 Overview

CVE-2025-13251 is a SQL injection vulnerability affecting WeiYe-Jing datax-web through version 2.1.2. The flaw resides in an unspecified function within the application and allows authenticated remote attackers to manipulate database queries. The exploit details have been published, increasing the likelihood of opportunistic abuse against exposed instances. The vulnerability is tracked under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component).

Critical Impact
Authenticated remote attackers can inject crafted SQL into datax-web requests, enabling unauthorized read or modification of backend database contents.

Affected Products

WeiYe-Jing datax-web versions up to and including 2.1.2
Deployments exposing the datax-web management interface to untrusted networks
Environments where datax-web shares a database with other sensitive applications

Technical Details for CVE-2025-13251

Vulnerability Analysis

datax-web is a distributed data synchronization scheduling platform built on top of the DataX engine. The application exposes management endpoints that accept user-controlled parameters and incorporate them into SQL statements processed by the backend database. CVE-2025-13251 stems from missing or insufficient input sanitization in one of these endpoints, allowing attackers to break out of the intended query context.

The weakness requires network reachability and a low-privileged authenticated session. Successful exploitation impacts confidentiality, integrity, and availability of the underlying database at a limited scope. According to public references, a proof-of-concept report has been published on GitHub, lowering the barrier to exploitation. See the GitHub SQL Injection Report and the VulDB entry #332585 for additional technical context.

Root Cause

The root cause is improper neutralization of special characters in SQL statements ([CWE-89]). The affected function concatenates attacker-controlled input into a SQL query rather than using parameterized statements or prepared statements with bound variables. As a result, payloads containing SQL metacharacters alter the query structure.

Attack Vector

An attacker authenticates to datax-web with low-privilege credentials and submits a crafted request to the vulnerable endpoint. The injected payload is interpreted by the database engine, allowing the attacker to read arbitrary tables, modify records, or perform timing-based blind extraction. The attack is remote and does not require user interaction.

No verified exploit code is included here. Refer to the public report linked above for technical details of the payload structure.

Detection Methods for CVE-2025-13251

Indicators of Compromise

HTTP request logs containing SQL metacharacters such as ', --, UNION SELECT, or SLEEP( in datax-web parameters
Unexpected database errors emitted by the datax-web backend during request processing
Anomalous query patterns in MySQL or PostgreSQL audit logs originating from the datax-web service account
Authenticated sessions from unfamiliar IP addresses issuing repeated parametrized requests to job or task endpoints

Detection Strategies

Deploy a web application firewall ruleset that inspects datax-web request parameters for SQL injection signatures
Enable database query logging and alert on syntactically malformed statements or use of UNION, SLEEP, or BENCHMARK in queries from the datax-web account
Correlate authentication events with subsequent high-volume or error-generating API requests to identify reconnaissance

Monitoring Recommendations

Forward datax-web application logs and database audit logs to a centralized log platform for retention and search
Establish baselines for expected query volume and error rates per authenticated user, alerting on deviations
Monitor outbound connections from the datax-web host that could indicate exfiltration following database compromise

How to Mitigate CVE-2025-13251

Immediate Actions Required

Restrict network access to datax-web management interfaces using firewall rules or VPN-only access
Rotate credentials for any low-privileged datax-web accounts that may have been reused or exposed
Review the database account used by datax-web and enforce least-privilege permissions, removing unnecessary write or administrative rights
Inspect database audit logs for evidence of prior exploitation matching the indicators above

Patch Information

At the time of publication, no fixed version is referenced in the NVD entry for datax-web. Organizations should monitor the datax-web project repository for security updates and apply any vendor-provided patches as soon as they become available.

Workarounds

Place datax-web behind an authenticating reverse proxy that restricts access to trusted operators only
Deploy a WAF with SQL injection signatures in front of datax-web until a patched version is released
Segment the datax-web database from other production databases to limit the blast radius of a successful injection
Disable or restrict any datax-web user accounts that are not required for current operations

bash

# Example: restrict datax-web access to a management subnet using iptables
iptables -A INPUT -p tcp --dport 9527 -s 10.0.10.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 9527 -j DROP
