How the Vulnerability Works
The CVE-2025-1832 vulnerability exists in the `getUserList` function within `ZroleAction.java` where improper sanitization of the `roleid` parameter allows SQL injection. Attackers can craft malicious SQL queries through this parameter, which are directly concatenated into the SQL statement. The application fails to use prepared statements or input validation, enabling remote execution of arbitrary database commands. This critical flaw exposes sensitive data like user credentials, permissions, and system configurations. The vulnerability is exploitable over the network without authentication, making it high-risk for exposed systems.

What Undercode Say:
-- Exploit PoC GET /system/zrole?roleid=1'%20UNION%20SELECT%201,username,password,4%20FROM%20users--
// Vulnerable Code Snippet
public String getUserList(String roleid) {
String sql = "SELECT FROM user_roles WHERE role_id = '" + roleid + "'";
return jdbcTemplate.query(sql);
}
// Secure Fix
public String getUserList(String roleid) {
String sql = "SELECT FROM user_roles WHERE role_id = ?";
return jdbcTemplate.query(sql, new Object[]{roleid});
}
Detection Command curl -s "http://target/system/zrole?roleid=1'" | grep -i "sql syntax"
-- Database Protection REVOKE DELETE,UPDATE ON user_roles FROM zz_app_user;
WAF Rule
location ~ /system/zrole {
if ($args ~ "([';]+|UNION.SELECT)") {
return 403;
}
}
Mitigation Script !/bin/bash sed -i 's/jdbcTemplate.query(sql)/jdbcTemplate.query(sql, args)/g' ZroleAction.java
// Input Validation
if (!roleid.matches("[0-9]+")) {
throw new IllegalArgumentException();
}
