Multiple Cisco Content Network and Video Delivery products contain a vulnerability that could allow an authenticated but unprivileged, remote attacker to execute arbitrary commands on a targeted device. Updates are available.
A vulnerability in the web
framework could allow an authenticated, remote attacker to execute
commands on the underlying operating system of the affected system as well as on underlying operating system of the devices associated and managed by the affected
vulnerability is due to a failure to properly sanitize user
input that is subsequently used to perform an action using the underlying command-line interface of the device. An authenticated but unprivileged attacker could exploit
this vulnerability by logging in to the GUI of the affected system and
appending arbitrary code to some of values passed to the system.
Cisco has confirmed the vulnerability in a security advisory and has released software updates.
Cisco has published a list of affected Cisco software releases in the security advisory. The Vendor Announcements section of this alert contains a link to the advisory.
To exploit this vulnerability, an attacker requires authenticated access to the targeted system. Authenticated access may require the attacker to access trusted, internal networks. These access requirements could limit the likelihood of a successful exploit.
Only devices running in management mode are affected by this vulnerability.
Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
An authenticated but unprivileged, remote attacker could exploit the vulnerability to execute arbitrary commands on the affected system and on the devices managed by the affected system itself and completely compromise the affected devices.
Additional technical details are not available.
Administrators are advised to apply the appropriate updates.
