2DescriptionCVE.org
An improper limitation of a pathname to a restricted directory ('path traversal') vulnerability in Desktop 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 attackers to write limited files and conduct limited denial-of-service attacks.
AnalysisAI
Unauthenticated path traversal in the Synology DiskStation Manager (DSM) Desktop API allows remote attackers to write a limited set of files and cause a limited denial-of-service condition on DSM instances older than 7.2.1-69057-10, 7.2.2-72806-7, or 7.3.2-86009-2. Because the CVSS vector is AV:N/AC:L/PR:N/UI:N, exploitation requires only network reachability to the DSM web management interface - no credentials or user interaction - though the impact is deliberately bounded: there is no confidentiality loss (C:N), with only low integrity and low availability effects from constrained file writes and partial service disruption. …

Vulnerability AssessmentAI
| Exploitation | Requires network access to the Synology DSM Desktop API (the web management desktop interface) on an unpatched DSM instance older than 7.2.1-69057-10 / 7.2.2-72806-7 / 7.3.2-86009-2. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuinely unauthenticated (PR:N) network-reachable path traversal, which raises its practical concern above the authenticated Synology siblings in the same Synology_SA_26_06 batch (e.g. … 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 | Vendor-released patch: Synology has published fixed builds 7.2.1-69057-10, 7.2.2-72806-7, and 7.3.2-86009-2 in security advisory SA_26_06 (https://www.synology.com/en-global/security/advisory/Synology_SA_26_06); update via DSM Control Panel > Update & Restore (or the branch-specific update path) to the build matching the deployed 7.2.1, 7.2.2, or 7.3.2 branch as soon as possible. … Detailed patch versions, workarounds, and compensating controls in full report. |
