CVE-2017-9800 allows attackers to execute arbitrary commands on a vulnerable version of SVN.
- Impact: Moderate
- CVSS3 Base Score: 4.8
- CVSS3 Base Metrics: CVSS:3.0/AV:L/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:L
- SVN before 1.9.7-0119
- All Synology models
A maliciously constructed svn+ssh:// URL would cause Subversion clients before 1.8.19, 1.9.x before 1.9.7, and 1.10.0.x through 1.10.0-alpha3 to run an arbitrary shell command. Such a URL could be generated by a malicious server, by a malicious user committing to a honest server (to attack another user of that server's repositories), or by a proxy server. The vulnerability affects all clients, including those that use file://, http://, and plain (untunneled) svn://.
Synology will soon release the updates for affected products.
