Cisco Bug: CSCuj22948 - Directory Traversal in VMWS Attachment Service
Jan 29, 2017
- Cisco Unity Connection
Known Affected Releases
8.6(4.1) 9.0(1.7) 9.1(1.10)
Symptom: Cisco Unity Connection contains a directory traversal vulnerability within the VMWS Attachment Service API. An authenticated, remote attacker could leverage this vulnerability to place files in arbitrary directories on the affected system for a short amount of time. The issue is due to a failure to properly sanitize user supplied input passed as part of the input string when supplying a filename to the VMWS attachment service. An attacker could leverage the vulnerability to write a file to any location that the <i>tomcat</i> user can access. This action could have extended secondary impacts on the device. Conditions: Cisco Unity Connection devices running version 7.x or unpatched 8.5, 8.6, or 9.1 software.
