CVE-2013-6987
Multiple directory traversal vulnerabilities in the FileBrowser components in Synology DiskStation Manager (DSM) before 4.3-3810 Update 3 allow remote attackers to read, write, and delete arbitrary files via a .. (dot dot) in the (1) path parameter to file_delete.cgi or (2) folder_path parameter to file_share.cgi in webapi/FileStation/; (3) dlink parameter to fbdownload/; or unspecified parameters to (4) html5_upload.cgi, (5) file_download.cgi, (6) file_sharing.cgi, (7) file_MVCP.cgi, or (8) file_rename.cgi in webapi/FileStation/.
CVSS
- Version: 2.0
- Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P
- Base score: 7.5
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 15%
- Percentile among all scored CVEs: 97
- Score date: 10/7/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
💥 Public exploits
Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
