Summary
Cisco BroadWorks Privilege Escalation Vulnerability

Notes

Summary
A vulnerability in the privilege management functionality of all Cisco BroadWorks server types could allow an authenticated, local attacker to elevate privileges to root on an affected system. This vulnerability is due to incorrect implementation of user role permissions. An attacker could exploit this vulnerability by authenticating to the application as a user with the BWORKS or BWSUPERADMIN role and issuing crafted commands on an affected system. A successful exploit could allow the attacker to execute commands beyond the sphere of their intended access level, including initiating installs or running operating system commands with elevated permissions. Cisco has released software updates that address this vulnerability. There are workarounds that address this vulnerability.
Vulnerable Products
At the time of publication, this vulnerability affected the following Cisco products if they were running a vulnerable release of Cisco BroadWorks Software: BroadWorks Application Delivery Platform BroadWorks Application Server BroadWorks Database Server BroadWorks Database Troubleshooting Server BroadWorks Execution Server BroadWorks Media Server BroadWorks Messaging Server BroadWorks Network Database Server BroadWorks Network Function Manager BroadWorks Network Server BroadWorks Profile Server BroadWorks Service Control Function Server BroadWorks Sharing Server BroadWorks Video Server BroadWorks WebRTC Server BroadWorks Xtended Services Platform For information about which Cisco software releases were vulnerable at the time of publication, see the Fixed Software ["#fs"] section of this advisory. See the Details section in the bug ID(s) at the top of this advisory for the most complete and current information.
Products Confirmed Not Vulnerable
Only products listed in the Vulnerable Products ["#vp"] section of this advisory are known to be affected by this vulnerability. Cisco has confirmed that this vulnerability does not affect the following Cisco products: BroadWorks Ansible Playbook BroadWorks pre-Install Check BroadWorks Service License Report Tool BroadWorks Software Manager
Workarounds
There is a workaround that addresses this vulnerability. From the CLI, comment out the following line from /etc/sudoers. The resulting line will be: # %wheel ALL=(ALL) ALL While this workaround has been deployed and was proven successful in a test environment, customers should determine the applicability and effectiveness in their own environment and under their own use conditions. Customers should be aware that any workaround or mitigation that is implemented may negatively impact the functionality or performance of their network based on intrinsic customer deployment scenarios and limitations. Customers should not deploy any workarounds or mitigations before first evaluating the applicability to their own environment and any impact to such environment.
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 table(s) 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. BroadWorks Application Delivery Platform, Media Server, and Service Control Function Server First Fixed Release Release Independent (RI) Rel_2023.05_1.291 Cisco BroadWorks Application Server First Fixed Release 22.0 and earlier Migrate to a fixed release. 23.0 AP.platform.23.0.1075.ap385253 24.0 AP.as.24.0.944.ap385253 Release Independent (RI) Rel_2023.05_1.292 BroadWorks Database Server, Execution Server, Network Database Server, and Network Function Manager First Fixed Release 22.0 and earlier Migrate to a fixed release. Release Independent (RI) Rel_2023.05_1.291 BroadWorks Database Troubleshooting Server First Fixed Release 22.0 and earlier Migrate to a fixed release. Release Independent (RI) Rel_2023.06_1.330 BroadWorks Network Server, Profile Server, and Xtended Services Platform First Fixed Release 22.0 and earlier Migrate to a fixed release. 23.0 AP.platform.23.0.1075.ap385253 Release Independent (RI) Rel_2023.05_1.291 The following products have reached the end-of-software-maintenance point in the end-of-life process. Cisco has not and will not release software updates to address this vulnerability for these products. BroadWorks Messaging Server BroadWorks Sharing Server BroadWorks Video Server BroadWorks WebRTC Server See the Cisco End-of-Life Policy ["https://www.cisco.com/c/en/us/products/eos-eol-policy.html"] for more information. The Cisco Product Security Incident Response Team (PSIRT) validates only the affected and fixed release information that is documented in this advisory.
