CVE-2025-12865: Edetw U-office Force SQLi Vulnerability

CVE-2025-12865 Overview

CVE-2025-12865 is a SQL injection vulnerability in U-Office Force, an office automation platform developed by e-Excellence (edetw). The flaw allows an authenticated remote attacker to inject arbitrary SQL commands into backend database queries. Successful exploitation enables attackers to read, modify, and delete database contents. The vulnerability is tracked under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). Taiwan CERT published advisories detailing the issue and affected versions.

Critical Impact
An authenticated attacker can compromise the confidentiality, integrity, and availability of all data stored in the U-Office Force database through injected SQL statements.

Technical Details for CVE-2025-12865

Vulnerability Analysis

The vulnerability is a classic SQL injection flaw [CWE-89] in U-Office Force. The application incorporates untrusted user-supplied input into SQL statements without proper sanitization or parameterization. An authenticated attacker with low privileges can craft input containing SQL syntax that the backend database engine then executes as part of a query.

Because the injected statements run with the privileges of the application's database account, attackers can extract sensitive records, alter business data, and remove rows or tables. The vulnerability is reachable over the network and requires no user interaction, lowering the operational cost of exploitation.

Root Cause

The root cause is improper neutralization of special elements in SQL commands. U-Office Force concatenates parameters into SQL queries instead of using parameterized statements or prepared queries. Input filtering and type validation are insufficient to block characters and tokens such as quotes, comments, and UNION clauses used to break out of intended query context.

Attack Vector

The attacker authenticates to U-Office Force using any valid low-privilege account. They then submit malicious payloads through parameters in HTTP requests that the application uses to build database queries. Typical techniques include union-based extraction, boolean-based blind injection, time-based blind injection, and stacked queries when the database driver permits them. The result is unauthorized read, write, and delete operations on the database.

No public exploit code or proof of concept is currently listed for this CVE, and it is not present in the CISA Known Exploited Vulnerabilities catalog. Refer to the Taiwan CERT Security Advisory (English) and the Taiwan CERT Security Advisory (Traditional Chinese) for vendor-coordinated details.

Detection Methods for CVE-2025-12865

Indicators of Compromise

Authenticated HTTP requests to U-Office Force endpoints containing SQL meta-characters such as ', ", --, ;, /*, or keywords like UNION SELECT, OR 1=1, SLEEP(, and BENCHMARK(.
Application or database logs showing syntax errors, unusually long query execution times, or large result sets returned to user-facing endpoints.
Unexpected modifications, deletions, or exports of database records correlated with a specific authenticated session.

Detection Strategies

Enable verbose query logging on the database server and alert on parse errors and statements originating from the U-Office Force application user outside of expected query templates.
Deploy a Web Application Firewall (WAF) ruleset for SQL injection signatures in front of U-Office Force and tune it against legitimate traffic baselines.
Correlate authenticated user activity with anomalous query volume, data egress, or off-hours administrative actions in security monitoring tooling.

Monitoring Recommendations

Monitor authentication logs for low-privilege accounts performing actions outside their normal role scope, such as accessing administrative modules.
Track outbound data transfers from servers hosting U-Office Force and the associated database tier for spikes consistent with bulk record extraction.
Alert on creation, modification, or deletion of database objects (tables, stored procedures, users) that fall outside scheduled maintenance windows.

How to Mitigate CVE-2025-12865

Immediate Actions Required

Apply the security update for U-Office Force as referenced in the Taiwan CERT advisories as soon as it is available from e-Excellence.
Restrict network access to U-Office Force to trusted internal networks or VPN users until the patch is deployed.
Audit and rotate credentials for all U-Office Force accounts, and disable any unused or default low-privilege accounts that could be abused for authenticated injection.
Review database audit logs for evidence of prior exploitation, including unexpected SELECT, UPDATE, and DELETE activity.

Patch Information

Refer to the vendor advisories published by Taiwan CERT for the fixed version and update procedure: Taiwan CERT Security Advisory (English) and Taiwan CERT Security Advisory (Traditional Chinese). Administrators should update to the version designated by e-Excellence as containing the SQL injection fix and verify the version after deployment.

Workarounds

Place a WAF or reverse proxy in front of U-Office Force with SQL injection rules enabled to block payloads containing common injection tokens.
Enforce least privilege on the database account used by U-Office Force so that the application cannot execute DROP, ALTER, or cross-database queries.
Limit application access to authenticated users on isolated network segments and require multi-factor authentication for all U-Office Force logins to raise the cost of obtaining the credentials needed to exploit the flaw.

bash

# Configuration example: restrict U-Office Force database account privileges
# Replace placeholders with environment-specific values.
REVOKE ALL PRIVILEGES ON *.* FROM 'uoffice_app'@'app-host';
GRANT SELECT, INSERT, UPDATE, DELETE ON uoffice_db.* TO 'uoffice_app'@'app-host';
FLUSH PRIVILEGES;
