An improper neutralization of special elements used in an SQL command ('SQL injection') vulnerability in Sharing API in Synology DiskStation Manager (DSM) before 7.2.1-69057-10, 7.2.2-72806-7 and 7.3.2-86009-2 allows remote authenticated users to obtain arbitrary sharing files.
AnalysisAI
An authenticated SQL injection in the Sharing API of Synology DiskStation Manager (DSM) allows remote users with valid - even low-privilege - DSM credentials to read arbitrary sharing files they should not be able to access. The flaw (CWE-89) affects DSM builds prior to 7.2.1-69057-10, 7.2.2-72806-7, and 7.3.2-86009-2, and is constrained by its credential prerequisite: no user interaction is required, but a logged-in session is, which limits it to a confidentiality-only impact (CVSS 6.5, C:H/I:N/A:N) rather than full system compromise. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated Synology DSM user account (PR:L) with network reach to the DSM Sharing API; no user interaction is needed. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a legitimate but bounded confidentiality issue rather than a top-tier emergency. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade DSM to the fixed build for your release train: 7.2.1-69057-10, 7.2.2-72806-7, or 7.3.2-86009-2 (vendor advisory: https://www.synology.com/en-global/security/advisory/Synology_SA_26_06). … Detailed patch versions, workarounds, and compensating controls in full report. |
