CVE-2024-50631 is a high-severity SQL Injection (CWE-89) vulnerability in Synology Drive Server. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 22.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
SI-10 directly prevents SQL injection by requiring validation and sanitization of inputs to neutralize special elements in SQL commands used by the syncing daemon.
SI-2 ensures timely patching of the SQL injection flaw in vulnerable Synology Drive Server versions to the fixed releases.
RA-5 enables vulnerability scanning to identify the SQL injection vulnerability in the system syncing daemon for remediation.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Unauthenticated remote SQL injection in public-facing Synology Drive Server syncing daemon directly enables T1190: Exploit Public-Facing Application for initial access; write-only limitation prevents mapping to collection or command execution techniques.
NVD Description
Improper neutralization of special elements used in an SQL command ('SQL Injection') vulnerability in the system syncing daemon in Synology Drive Server before 3.0.4-12699, 3.2.1-23280, 3.5.0-26085 and 3.5.1-26102 allows remote attackers to inject SQL commands, limited to write operations, via…

Deeper analysisAI
CVE-2024-50631 is an SQL injection vulnerability (CWE-89) in the system syncing daemon of Synology Drive Server. It affects versions prior to 3.0.4-12699, 3.2.1-23280, 3.5.0-26085, and 3.5.1-26102. The flaw stems from improper neutralization of special elements used in an SQL command, enabling remote attackers to inject SQL commands limited to write operations via unspecified vectors. The vulnerability carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N).
Remote attackers without privileges can exploit this vulnerability over the network with low complexity and no user interaction required. Successful exploitation allows injection of SQL commands that perform write operations, resulting in high integrity impact but no confidentiality or availability disruption.
The Synology security advisory (Synology_SA_24_21) provides details on mitigation, which involves updating to Synology Drive Server versions 3.0.4-12699, 3.2.1-23280, 3.5.0-26085, or 3.5.1-26102, depending on the branch.
