Summary

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 2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

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. Security practitioners should review the full advisory at https://www.synology.com/en-global/security/advisory/Synology_SA_24_21 for patch deployment guidance.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover SQLi flaws before deployment but does not stop their introduction.

Input validation directly stops untrusted data from reaching SQL query construction without neutralization.

Secure engineering principles require parameterized queries and input sanitization that structurally eliminate SQLi.

System monitoring can identify attempted SQLi exploitation via anomalous queries after the weakness exists.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly target injection flaws during coding and review so largely prevent CWE-89 introduction, yet the single broad outcome leaves residual risk from incomplete neutralization techniques or missed edge cases.

PR.AT-02 partial match
prevents

Training raises developer awareness of SQLi risks and can reduce introduction likelihood (partial) but removes none of the actual coding flaw's risk by itself since technical neutralization is still required.

finds

The same secure-coding and static-analysis activities surface missing neutralization of SQL metacharacters before the system is accepted.

prevents

Early warnings and shared best-practice information help organizations apply the latest remediation techniques against SQL-injection vulnerabilities.

prevents

Threat-intelligence feeds that surface new SQL-injection campaigns enable rapid updates to query-construction defenses and detection signatures before exploitation occurs.

prevents

Secure-coding rules and security testing phases mandate the use of parameterized queries or equivalent escaping, preventing the construction of dynamic SQL statements from untrusted input.

prevents

Language-specific secure coding rules, peer review and SAST together prevent the construction of SQL statements from untrusted data without proper parameterization or escaping.
