https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-broadworks-dJ9JT67N
Affected Products
o Vulnerable Products
At the time of publication, these vulnerabilities affected Cisco BroadWorks
CommPilot Application Software releases earlier than a fixed release if
they implemented user access control through the web-based management
interface to restrict access for the read-only system administrator role.
For information about which Cisco software releases were vulnerable at the
time of publication, see the Fixed Software 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 section of this advisory
are known to be affected by these vulnerabilities.
Details
o The vulnerabilities are not dependent on one another. Exploitation of one
of the vulnerabilities is not required to exploit the other vulnerability.
In addition, a software release that is affected by one of the
vulnerabilities may not be affected by the other vulnerability.
Details about the vulnerabilities are as follows:
CVE-2021-34785: Cisco BroadWorks CommPilot Application Software Privilege
Escalation Vulnerability
A vulnerability in the web-based management interface of Cisco BroadWorks
CommPilot Application Software could allow an authenticated, remote
attacker to gain elevated privileges.
This vulnerability is due to improper authorization checks on operations in
the affected application. An attacker with read-only system administrator
privileges could exploit this vulnerability by sending crafted requests to
the application. A successful exploit could allow the attacker to modify an
existing system administrator account and assume the privileges of the
targeted account, resulting in privilege escalation.
Cisco has released software updates that address this vulnerability. There
are no workarounds that address this vulnerability.
