Description

SEMCMS 3.9 is vulnerable to SQL Injection. Due to the lack of security checks on the input of the application, the attacker uses the existing application to inject malicious SQL commands into the background database engine for execution, and sends some attack codes as commands or query statements to the interpreter. These malicious data can deceive the interpreter, so as to execute unplanned commands or unauthorized access to data.

Technical Analysis

CVE-2023-48863 is a high-severity SQL Injection vulnerability affecting SEMCMS version 3.9. The vulnerability arises from insufficient input validation and sanitization in the application, allowing an attacker to inject malicious SQL commands directly into the backend database engine. This injection enables the attacker to manipulate the database queries executed by the application, potentially bypassing intended logic and security controls. The vulnerability does not require any authentication or user interaction, making it remotely exploitable over the network. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) indicates that the attack can be performed remotely with low attack complexity, no privileges, and no user interaction, resulting in a high impact on confidentiality but no impact on integrity or availability. Specifically, the attacker can extract sensitive data from the database without authorization, which could include user credentials, personal data, or other confidential information stored by SEMCMS. Although no known exploits are currently reported in the wild, the nature of SQL Injection vulnerabilities and their ease of exploitation make this a significant risk. The lack of available patches or vendor information increases the urgency for organizations using SEMCMS 3.9 to implement mitigations promptly. The vulnerability is categorized under CWE-89, a well-known and commonly exploited weakness in web applications that interact with databases.

Potential Impact

For European organizations using SEMCMS 3.9, this vulnerability poses a serious risk to the confidentiality of sensitive data. Unauthorized data disclosure could lead to violations of GDPR and other data protection regulations, resulting in legal penalties and reputational damage. The ability to extract confidential information without authentication increases the threat level, especially for organizations handling personal data, financial information, or intellectual property. Although the vulnerability does not directly impact data integrity or availability, the exposure of sensitive data can facilitate further attacks such as identity theft, fraud, or targeted phishing campaigns. The absence of known exploits in the wild currently provides a limited window for proactive defense, but the ease of exploitation and the high confidentiality impact necessitate immediate attention. European organizations in sectors such as government, finance, healthcare, and critical infrastructure that rely on SEMCMS for content management or internal applications are particularly at risk.

Mitigation Recommendations

Since no official patches or vendor advisories are currently available, European organizations should implement the following specific mitigations: 1) Conduct a thorough audit of all SEMCMS 3.9 instances to identify exposed endpoints that accept user input potentially vulnerable to SQL Injection. 2) Employ Web Application Firewalls (WAFs) with SQL Injection detection and prevention rules tailored to block malicious payloads targeting SEMCMS. 3) Implement strict input validation and sanitization at the application layer, using parameterized queries or prepared statements wherever possible to prevent injection. 4) Restrict database user permissions to the minimum necessary, limiting the scope of data accessible in case of exploitation. 5) Monitor database query logs and application logs for anomalous or suspicious queries indicative of injection attempts. 6) Consider isolating SEMCMS instances in segmented network zones to reduce lateral movement risk. 7) Prepare incident response plans specifically for data breach scenarios involving SQL Injection. 8) Stay alert for vendor updates or community patches and apply them immediately upon release. These measures go beyond generic advice by focusing on compensating controls and proactive detection in the absence of a patch.
