CVE-2026-38808: uzy-ssm-mall SQL Injection Vulnerability

CVE-2026-38808 Overview

CVE-2026-38808 is a SQL Injection vulnerability affecting uzy-ssm-mall version 1.1.0. The flaw resides in the ProductMapper.xml and /OrderUtil.java components of the application. A remote attacker can inject malicious SQL statements through unsanitized input parameters processed by these components. Successful exploitation allows the attacker to retrieve sensitive information from the backend database without authentication context guarantees.

uzy-ssm-mall is an open-source e-commerce mall application built on the Spring, Spring MVC, and MyBatis (SSM) framework. The vulnerability was disclosed through a public GitHub issue tracker. See the GitHub CVE Issue Discussion for the original report.

Critical Impact
Remote attackers can extract sensitive database contents from uzy-ssm-mall v1.1.0 deployments by injecting SQL through vulnerable mapper and utility components.

Affected Products

uzy-ssm-mall v1.1.0

Technical Details for CVE-2026-38808

Vulnerability Analysis

The vulnerability is a classic SQL Injection flaw [CWE-89] introduced through unsafe construction of SQL queries in two distinct code paths within uzy-ssm-mall v1.1.0. The first path is in ProductMapper.xml, a MyBatis mapper file that defines SQL statements bound to Java interfaces. The second is in /OrderUtil.java, a helper class involved in order processing.

When user-supplied parameters reach these components without parameterization, the application concatenates them directly into SQL strings. The database engine then interprets attacker-controlled fragments as executable SQL syntax. This breaks the boundary between code and data, allowing query logic manipulation.

Root Cause

The root cause is improper neutralization of special elements used in an SQL command. In MyBatis mapper XML files, developers can reference parameters using either #{param} for prepared statement binding or ${param} for direct string substitution. Use of ${param} syntax with untrusted input produces SQL injection. A parallel concatenation pattern in OrderUtil.java extends the same defect to the order handling flow.

Attack Vector

A remote attacker submits crafted input through HTTP request parameters that are routed to the vulnerable mapper or utility method. The injected payload alters the query to return additional rows, dump table contents, or perform boolean and time-based blind extraction. No special privileges are required when the affected endpoints are reachable by anonymous or low-privilege users.

No verified proof-of-concept code is published in the source advisory. Refer to the GitHub CVE Issue Discussion for reproduction context.

Detection Methods for CVE-2026-38808

Indicators of Compromise

Web server access logs containing SQL meta-characters such as ', --, UNION SELECT, SLEEP(, or INFORMATION_SCHEMA in parameters targeting product or order endpoints.
Database error messages or stack traces referencing ProductMapper or OrderUtil returned in HTTP responses.
Anomalous database query volume or long-running queries originating from the uzy-ssm-mall application user.

Detection Strategies

Deploy a Web Application Firewall (WAF) rule set that inspects request parameters for SQL injection patterns before they reach the application.
Enable MyBatis SQL logging in non-production environments to identify dynamically constructed statements that use ${} substitution.
Correlate authentication, application, and database logs to detect query patterns inconsistent with normal product or order workflows.

Monitoring Recommendations

Monitor outbound database query patterns for UNION-based reads against tables outside the typical product and order scope.
Alert on HTTP 500 responses from product or order endpoints, which frequently accompany blind SQL injection probing.
Track repeated requests from a single source with incrementing payload lengths, indicating automated injection tooling.

How to Mitigate CVE-2026-38808

Immediate Actions Required

Restrict network access to uzy-ssm-mall v1.1.0 deployments until a patched version is available from the project maintainers.
Review and refactor ProductMapper.xml to replace any ${param} substitutions with #{param} prepared statement bindings.
Audit /OrderUtil.java for string-concatenated SQL and convert to parameterized queries using MyBatis or JDBC PreparedStatement.

Patch Information

No official vendor patch is referenced in the NVD entry at the time of publication. Operators should monitor the upstream uzy-ssm-mall repository and the GitHub CVE Issue Discussion for remediation updates.

Workarounds

Deploy a WAF in front of the application with rules targeting SQL injection signatures on product and order request parameters.
Apply least-privilege principles to the database account used by the application, removing rights to system tables and unrelated schemas.
Disable or firewall affected endpoints if they are not required for production operation.

bash

# Example least-privilege grant for the application database user
REVOKE ALL PRIVILEGES ON *.* FROM 'ssm_mall_app'@'%';
GRANT SELECT, INSERT, UPDATE, DELETE ON ssm_mall.* TO 'ssm_mall_app'@'%';
FLUSH PRIVILEGES;
