Abstract

CVE-2017-9800 allows attackers to execute arbitrary commands on a vulnerable version of SVN.

Severity

Affected

  • Products
    • SVN before 1.9.7-0119
  • Models
    • All Synology models

Description

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://.

Mitigation

None

Update Availability

To fix the security issue, please go to DSM > Package Center and update SVN to 1.9.7-0119 or above.
