Published: 19 March 2025
Summary
CVE-2024-10442 is a critical-severity Off-by-one Error (CWE-193) vulnerability in Synology Diskstation Manager. Its CVSS base score is 10.0 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 5.4% 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-2 (Flaw Remediation) and RA-5 (Vulnerability Monitoring and Scanning).
Deeper analysis
CVE-2024-10442 is an off-by-one error vulnerability (CWE-193) in the transmission component of Synology Replication Service versions prior to 1.0.12-0066, 1.2.2-0353, and 1.3.0-0423, as well as Synology Unified Controller (DSMUC) versions prior to 3.1.4-23079. The flaw carries a CVSS 3.1 score of 10.0 and permits remote code execution with full system impact across confidentiality, integrity, and availability.
Unauthenticated attackers with network access can exploit the issue without user interaction to run arbitrary code on affected systems, potentially compromising the broader environment through unspecified vectors.
The official Synology advisory Synology_SA_24_22 recommends updating Replication Service and DSMUC to the fixed releases listed above to address the vulnerability.
The associated EPSS score remains flat at 0.1459 with no material increase observed since disclosure.
