Summary
Cisco BroadWorks Privilege Escalation Vulnerability

Notes

Summary
A vulnerability in Cisco BroadWorks could allow an authenticated, local attacker to elevate privileges to the root user on an affected device. The vulnerability is due to insufficient input validation by the operating system CLI. An attacker could exploit this vulnerability by issuing a crafted command to the affected system. A successful exploit could allow the attacker to execute commands as the root user. To exploit this vulnerability, an attacker must have valid BroadWorks administrative privileges on the affected device. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Fixed Software
When considering software upgrades ["https://sec.cloudapps.cisco.com/security/center/resources/security_vulnerability_policy.html#fixes"], customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories page ["https://www.cisco.com/go/psirt"], to determine exposure and a complete upgrade solution. In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers. Fixed Releases At the time of publication, the release information in the following tables was accurate. See the Details section in the bug ID(s) at the top of this advisory for the most complete and current information. The left column lists Cisco software releases, and the right column indicates whether a release was affected by the vulnerability that is described in this advisory and which release included the fix for this vulnerability.
