Security Intelligence Brief
1. What is this vulnerability and why does it matter?
This is an SQL Injection vulnerability (CWE-89) affecting the system syncing daemon in Synology Drive Server. It allows remote attackers to inject SQL commands. The vulnerability matters because SQL injection can lead to unauthorized modification of data, potentially compromising data integrity, availability, and in some cases, lead to further system compromise, even if limited to write operations as stated here.
2. What are the CVSS score, severity level, and disclosure details?
- CVSS Score: 7.5
- Severity Level: High
- Disclosure Details: The vulnerability was published on 2025-03-19 05:50:08 and last modified on 2025-03-19 14:37:54.
3. Which products, vendors, systems, and versions are affected?
- Vendor: Synology
- Product: Synology Drive Server
- Affected Component: System syncing daemon
- Affected Versions:
- Synology Drive Server versions before 3.0.4-12699
- Synology Drive Server versions before 3.2.1-23280
- Synology Drive Server versions before 3.5.0-26085
- Synology Drive Server versions before 3.5.1-26102
4. What is the technical root cause and attack vector?
- Technical Root Cause: The root cause is an improper neutralization of special elements used in an SQL command, commonly known as SQL Injection (CWE-89). This indicates that user-supplied input is not adequately sanitized or escaped before being incorporated into SQL queries by the system syncing daemon.
- Attack Vector: The vulnerability allows remote attackers to inject SQL commands via unspecified vectors. This implies that exploitation can occur over a network without requiring local access or specific user interaction beyond sending crafted input.
5. How can this vulnerability be exploited?
This vulnerability can be exploited by a remote attacker who crafts and sends malicious input that contains SQL commands to the system syncing daemon of an affected Synology Drive Server instance. The improper handling of special characters in this input allows the attacker's SQL commands to be executed within the server's database context. The exploitation is explicitly stated to be limited to write operations, meaning an attacker can modify existing data or insert new data into the database. The specific "unspecified vectors" imply the exact method of delivering the malicious input is not publicly detailed in this CVE entry.
6. What mitigation steps and patches are available?
The primary mitigation step is to update the Synology Drive Server to a patched version. The following versions are known to contain fixes for this vulnerability:
- Synology Drive Server 3.0.4-12699 and later
- Synology Drive Server 3.2.1-23280 and later
- Synology Drive Server 3.5.0-26085 and later
- Synology Drive Server 3.5.1-26102 and later
7. How can vulnerable systems be detected?
Vulnerable systems can be detected by checking the installed version of Synology Drive Server. Any instance running a version older than 3.0.4-12699, 3.2.1-23280, 3.5.0-26085, or 3.5.1-26102 (depending on the major release branch) is considered vulnerable. System administrators should verify their Synology Drive Server version through the administrative interface or command line.
10. What public intelligence references and advisories exist?
- CVE ID: CVE-2024-50631
- CWE ID: CWE-89 (Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection'))
- Published Date: 2025-03-19 05:50:08
- Modified Date: 2025-03-19 14:37:54
11. What is the risk assessment and urgency level?
The risk assessment for CVE-2024-50631 is High, indicated by a CVSS score of 7.5. The vulnerability allows remote SQL injection with write capabilities, meaning an attacker can modify data within the Synology Drive Server's database. This could lead to data integrity compromise, service disruption, or unauthorized configuration changes. The urgency level for patching is High, especially for systems exposed to the internet or untrusted networks, due to the remote attack vector and the potential for significant impact on data and service availability. Immediate application of available patches is strongly recommended.
