CVE-2024-10731: Tongda2000 Office Anywhere SQLi Vulnerability

CVE-2024-10731 Overview

CVE-2024-10731 is a SQL injection vulnerability in Tongda Office Anywhere (Tongda OA) versions up to 11.10. The flaw resides in the /pda/appcenter/check_seal.php script, where the ID parameter is passed to a database query without proper sanitization. Attackers can manipulate the ID argument to inject arbitrary SQL statements. The vulnerability is exploitable remotely over the network and requires low-level authenticated access. Public disclosure of the exploit details has occurred through VulDB and a GitHub issue, increasing the likelihood of opportunistic exploitation against exposed Tongda OA deployments.

Critical Impact

Authenticated remote attackers can inject arbitrary SQL queries through the ID parameter, enabling unauthorized data access, modification, and potential lateral movement within the Tongda OA backend database.

Affected Products

• Tongda2000 Office Anywhere versions up to and including 11.10
• Vulnerable component: /pda/appcenter/check_seal.php
• Deployments exposing the PDA application module to network-reachable users

Technical Details for CVE-2024-10731

Vulnerability Analysis

The vulnerability is classified under [CWE-89] Improper Neutralization of Special Elements used in an SQL Command. The affected endpoint /pda/appcenter/check_seal.php accepts an ID parameter from the client and incorporates it directly into a backend SQL query. Because the parameter is not sanitized or bound through a parameterized query, supplied input is interpreted as part of the SQL statement.

Exploitation produces measurable impact on confidentiality, integrity, and availability of the database. An authenticated attacker can read sensitive records, modify business data, or enumerate database schema using time-based or boolean-based blind injection techniques. Tongda OA stores workflow, document, and personnel data, so successful exploitation has direct operational consequences for organizations using the platform.

Root Cause

The root cause is the absence of input validation and prepared statements when handling the ID request parameter inside check_seal.php. PHP scripts in the affected build concatenate user-supplied values into SQL strings rather than using parameterized queries provided by the underlying database driver.

Attack Vector

The attack vector is remote over HTTP or HTTPS. An attacker with valid low-privilege credentials sends a crafted request to the PDA application endpoint with a malicious payload in the ID parameter. No user interaction is required. The publicly disclosed exploit lowers the skill barrier for adversaries targeting internet-exposed Tongda OA instances.

For technical specifics on the injection vector, see the GitHub Issue Discussion and the VulDB entry #282900.

Detection Methods for CVE-2024-10731

Indicators of Compromise

• HTTP requests to /pda/appcenter/check_seal.php containing SQL metacharacters such as single quotes, UNION, SELECT, SLEEP(, or comment sequences in the ID parameter
• Unusually long or URL-encoded ID parameter values in web server access logs
• Database error messages or anomalous query latency originating from the check_seal.php workflow
• Unexpected outbound database connections or large result-set transfers following requests to the affected endpoint

Detection Strategies

• Deploy web application firewall rules that inspect the ID parameter on /pda/appcenter/check_seal.php for SQL syntax tokens and block matches
• Correlate authenticated user sessions with bursts of requests to check_seal.php to identify automated injection probing
• Monitor database audit logs for queries originating from the PDA module that include UNION, INFORMATION_SCHEMA, or stacked statements

Monitoring Recommendations

• Enable verbose access logging on the Tongda OA web tier and forward logs to a centralized analytics platform
• Alert on HTTP 500 responses from /pda/appcenter/check_seal.php, which often indicate failed injection attempts
• Track failed and successful authentications preceding requests to the vulnerable endpoint to identify credential abuse

How to Mitigate CVE-2024-10731

Immediate Actions Required

• Restrict network access to the Tongda OA PDA module to trusted internal networks or VPN clients until a vendor patch is applied
• Audit existing accounts and revoke credentials that do not require access to the PDA application
• Review web server and database logs for prior exploitation attempts against check_seal.php
• Rotate any credentials or session tokens that may have been exposed through the affected database tables

Patch Information

No vendor advisory or patch URL is referenced in the published CVE data. Operators of Tongda Office Anywhere 11.10 and earlier should contact Tongda2000 directly for a fixed release and monitor the VulDB submission report for updates.

Workarounds

• Place the Tongda OA application behind a web application firewall with a virtual patch blocking SQL syntax in the ID parameter of check_seal.php
• Disable or remove the /pda/appcenter/check_seal.php endpoint if the PDA seal-check functionality is not used in the deployment
• Enforce least-privilege database accounts so the web application user cannot read sensitive tables or execute administrative SQL
• Require multi-factor authentication on all Tongda OA user accounts to reduce the population of attackers able to reach the authenticated endpoint
