First Published: 2019 June 19 16:00 GMT
Version 1.0: Final
Workarounds: No workarounds availableCisco Bug IDs: CSCvi46909CSCvi59723CSCvi59724
CVE-2019-1624
CWE-77
CVSS Score:
8.8 AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:X/RL:X/RC:X
Summary
o
A vulnerability in the vManage web-based UI (Web UI) in the Cisco SD-WAN
Solution could allow an authenticated, remote attacker to inject arbitrary
commands that are executed with root privileges.
The vulnerability is due to insufficient input validation. An attacker
could exploit this vulnerability by authenticating to the device and
submitting crafted input to the vManage Web UI. A successful exploit could
allow the attacker to execute commands with root privileges.
Cisco has released software updates that address this vulnerability. There
are no workarounds that address this vulnerability.

is running a release of the Cisco SD-WAN Solution prior to Release 18.4.0.
Products Confirmed Not Vulnerable
Only products listed in the Vulnerable Products section of this advisory
are known to be affected by this vulnerability.
Workarounds
o There are no workarounds that address this vulnerability.
Fixed Software
o Cisco has released free software updates that address the vulnerability
described in this advisory. Customers may only install and expect support

CVSS Score:
8.8 AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:X/RL:X/RC:X
Summary
o A vulnerability in the vManage web-based UI (Web UI) of the Cisco SD-WAN
Solution could allow an authenticated, remote attacker to gain elevated
