CVE-2025-12864: U-Office Force SQL Injection Vulnerability

CVE-2025-12864 Overview

CVE-2025-12864 is a SQL Injection vulnerability in U-Office Force, an office automation product developed by e-Excellence (edetw). An authenticated remote attacker can inject arbitrary SQL commands through vulnerable input parameters. Successful exploitation allows the attacker to read, modify, and delete database contents. The flaw is categorized under CWE-89, Improper Neutralization of Special Elements used in an SQL Command. The vulnerability was reported through TW-CERT, Taiwan's national computer emergency response team.

Critical Impact
Authenticated attackers can execute arbitrary SQL commands against the backend database, compromising confidentiality, integrity, and availability of stored data.

Affected Products

U-Office Force by e-Excellence (edetw)
All versions prior to the vendor-supplied fix referenced in the TW-CERT advisory
Deployments exposing the U-Office Force web interface to authenticated users

Technical Details for CVE-2025-12864

Vulnerability Analysis

The vulnerability resides in U-Office Force's handling of user-supplied input within database query construction. The application concatenates attacker-controlled values into SQL statements without proper parameterization or sanitization. An authenticated user can submit crafted parameters that break out of the intended query context and append arbitrary SQL syntax.

Because the issue affects backend queries, attackers gain direct access to stored data. This includes the ability to enumerate tables, extract sensitive records, alter rows, and drop database objects. The attack requires only low privileges and no user interaction, increasing the practical exploitability against multi-tenant or shared deployments.

Root Cause

The root cause is improper neutralization of special characters in SQL statements ([CWE-89]). U-Office Force constructs queries through string concatenation instead of using parameterized statements or prepared queries. The absence of input validation and output encoding allows metacharacters such as single quotes, semicolons, and SQL keywords to alter query logic.

Attack Vector

The attack vector is network-based and requires valid authentication to the U-Office Force application. An attacker with any authenticated session sends crafted HTTP requests containing SQL payloads in vulnerable parameters. The server processes the injected SQL with the privileges of the application's database account, which typically holds broad read and write access to the application schema. Technical specifics are documented in the TW-CERT Security Advisory.

Detection Methods for CVE-2025-12864

Indicators of Compromise

Unusual SQL syntax in HTTP request parameters such as UNION SELECT, OR 1=1, --, ;, or hex-encoded payloads sent to U-Office Force endpoints
Database error messages returned to authenticated users or recorded in application logs
Unexpected SELECT, UPDATE, or DELETE operations against sensitive tables originating from the U-Office Force service account
New or modified administrative accounts inside the application database without corresponding workflow events

Detection Strategies

Deploy a web application firewall (WAF) with SQL injection rule sets in front of U-Office Force and alert on blocked payloads
Enable database query logging and review for query patterns inconsistent with normal application behavior
Correlate authenticated session activity with database write operations to identify abuse of low-privilege accounts
Monitor application server logs for HTTP 500 responses tied to malformed SQL syntax

Monitoring Recommendations

Establish a baseline of legitimate query shapes issued by U-Office Force and alert on deviations
Forward web and database logs to a centralized analytics platform for long-term retention and correlation
Track failed login attempts followed by parameter tampering from the same source address
Review privileged database role assignments on a recurring basis

How to Mitigate CVE-2025-12864

Immediate Actions Required

Apply the vendor patch referenced in the TW-CERT Security Advisory as soon as it is available for your deployment
Restrict network access to the U-Office Force interface to trusted users and management networks
Rotate credentials for any accounts that may have been used to exploit the application
Audit the application database for unauthorized data modifications since the last known-good backup

Patch Information

E-Excellence has coordinated remediation through TW-CERT. Administrators should consult the TW-CERT Security Notification and the TW-CERT Security Advisory for the fixed version and upgrade instructions. Apply the update across all U-Office Force instances and verify the version after deployment.

Workarounds

Place a WAF with SQL injection signatures in blocking mode in front of the application until the patch is applied
Limit the database account used by U-Office Force to the minimum privileges required, removing DROP and schema-altering permissions where possible
Disable or restrict access to application features known to expose vulnerable parameters if identified by the vendor
Require multi-factor authentication for all U-Office Force users to reduce the pool of accounts that could be leveraged for exploitation
