CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
CWE-74 The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

Executive Summary

[{'type': 'paragraph', 'content': 'CVE-2026-4234 is a SQL injection vulnerability found in SSCMS version 7.4.0, specifically in the file SitesAddController.Submit.cs within the DDL Handler component.'}, {'type': 'paragraph', 'content': "The vulnerability arises from improper handling of the argument 'tableHandWrite', which is user-controlled input that is directly incorporated into dynamic SQL Data Definition Language statements like CREATE TABLE and CREATE INDEX without proper validation."}, {'type': 'paragraph', 'content': 'The existing protection uses blacklist filtering and identifier wrapping, but this is insufficient to prevent malicious input that can break the intended SQL structure.'}, {'type': 'paragraph', 'content': 'As a result, an attacker can inject malicious SQL commands remotely, potentially modifying the database schema or extracting information using time-based blind SQL injection techniques.'}, {'type': 'paragraph', 'content': 'The vulnerability corresponds to CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) and can be exploited without authentication.'}] [2, 3]

Impact Analysis

[{'type': 'paragraph', 'content': 'This vulnerability can impact you by allowing remote attackers to execute unauthorized SQL commands on your SSCMS 7.4.0 system.'}, {'type': 'paragraph', 'content': "Such exploitation can lead to unauthorized modifications of the database schema, extraction of sensitive information, and compromise of the system's confidentiality, integrity, and availability."}, {'type': 'paragraph', 'content': 'Because the attack can be performed remotely without authentication, it increases the risk of exploitation.'}, {'type': 'paragraph', 'content': 'No known patches or mitigations exist, so affected systems remain vulnerable unless the component or product is replaced.'}] [2, 3]

Compliance Impact

I don't know

Detection Guidance

[{'type': 'paragraph', 'content': "This vulnerability involves SQL injection through the argument 'tableHandWrite' in SSCMS 7.4.0. Detection can focus on monitoring for unusual or malicious SQL commands targeting this parameter."}, {'type': 'paragraph', 'content': "Since the vulnerability allows remote exploitation via SQL injection, network detection could involve inspecting HTTP requests for suspicious payloads in the 'tableHandWrite' parameter."}, {'type': 'paragraph', 'content': 'No specific detection commands or signatures are provided in the available resources.'}] [2, 3]

Mitigation Strategies

There are no known patches or countermeasures available from the vendor, as they did not respond to the disclosure.

Immediate mitigation steps include considering replacing the affected component or product to avoid exploitation.

Since the vulnerability allows remote SQL injection without authentication, restricting access to the affected service and monitoring for suspicious activity may help reduce risk temporarily.
