Cisco Security Advisory
Cisco Application Policy Infrastructure Controller Privilege Escalation Vulnerability
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:N/E:X/RL:X/RC:X
-
A vulnerability in the software upgrade component of Cisco Application Policy Infrastructure Controller (APIC) and Cisco Cloud Network Controller, formerly Cisco Cloud APIC, could allow an authenticated, remote attacker with Administrator-level privileges to install a modified software image, leading to arbitrary code injection on an affected system.
This vulnerability is due to insufficient signature validation of software images. An attacker could exploit this vulnerability by installing a modified software image. A successful exploit could allow the attacker to execute arbitrary code on the affected system and elevate their privileges to root.
Note: Administrators should always validate the hash of any upgrade image before uploading it to Cisco APIC and Cisco Cloud Network Controller.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
