Cisco Security Advisory
Cisco Prime Infrastructure Arbitrary File Upload and Command Execution
Vulnerability
Priority: Critical
Advisory ID: cisco-sa-20181003-pi-tftp
First Published: 2018 October 3 16:00 GMT
Version 1.0: Final
Workarounds: Yes
Cisco Bug IDs: CSCvk24890
CVE-2018-15379
CWE-275
CVSS Score: Base 7.3
CVSS: 3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L/E:X/RL:X/RC:X
Summary
o A vulnerability in which the HTTP web server for Cisco Prime Infrastructure
(PI) has unrestricted directory permissions could allow an unauthenticated,
remote attacker to upload an arbitrary file. This file could allow the
attacker to execute commands at the privilege level of the user prime. This
user does not have administrative or root privileges.
The vulnerability is due to an incorrect permission setting for important
system directories. An attacker could exploit this vulnerability by
uploading a malicious file by using TFTP, which can be accessed via the
web-interface GUI. A successful exploit could allow the attacker to run
commands on the targeted application without authentication.
Cisco has released software updates that address this vulnerability. There
are workarounds that address this vulnerability.
This advisory is available at the following link:
https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181003-pi-tftp
Affected Products
o Vulnerable Products
Cisco PI Software Releases 3.2 through 3.4 prior to the first fixed release
are vulnerable if the TFTP server is enabled, which is the default setting.
The administrator can check the TFTP status by navigating in the web
interface to Administration > Settings > System Settings > Server > TFTP.
The PI Federal Information Processing Standards (FIPS) image has TFTP
disabled by default.
Determining the PI Software Release
To determine the software release that is running on the appliance,
administrators can use one of the following methods.
- The administrator can issue the show version command in the console
CLI. The following output is from an affected application running PI
Software Release 3.2.0 with PI Maintenance Release 3.2.2 installed:
piconsole# show version
Cisco Application Deployment Engine OS Release: 3.2
ADE-OS Build Version: 3.2.0.001
ADE-OS System Architecture: x86_64

Version information of installed applications
---------------------------------------------
Cisco Prime Infrastructure
********************************************************
Version : 3.2.0
Build : 3.2.0.0.132
Critical Fixes:
PI 3.2.2 Maintenance Release ( 6.0.0 )
Device Support:
Prime Infrastructure 3.2 Device Pack 11 ( 11.0 )
- The administrator can also view the PI release and maintenance release
updates by logging in to the web interface using the http(s)://
<system-ip> access URL. The PI software release is displayed on the
welcome screen and the administrator can click View Installed Update,
which opens a pop-up window with a list of PI maintenance releases and
patches. The following is an example of text that is displayed in the
pop-up window for PI Software Release 3.2:
Cisco Prime Infrastructure
Version 3.2
View Installed Update
The pop-up window will display the list of maintenance release
updates in the following format:
Update Name
PI 3.2.2 Maintenance Release
- The administrator can also view the PI release and maintenance release
updates by logging in to the web interface using the http(s)://
<system-ip> access URL and navigating to the Gear > About Prime
Infrastructure > View Installed Updates screen. The release information
is displayed as follows:
Installed Updates
Critical Fixes
Update Name Version
PI 3.2.2 Maintenance Rel... 6.0.0
Device Support
Update Name
Prime Infrastructure 3.2
Products Confirmed Not Vulnerable
Only products listed in the Vulnerable Products section of this advisory
are known to be affected by this vulnerability.
Cisco has confirmed that Cisco Evolved Programmable Network Manager (EPNM)
is not vulnerable.
Workarounds
o The administrator can disable TFTP for Cisco PI by navigating in the web
interface to Administration > Settings > System Settings > Server > TFTP.
In Cisco PI, TFTP is used for internal operations such as image transfer,
configuration, and archives. The administrator can instead use a secure
protcotol such as Secure Copy Protocol (SCP) or SFTP for these functions.
Fixed Software
o Cisco has released free software updates that address the vulnerability
described in this advisory. Customers may only install and expect support
for software versions and feature sets for which they have purchased a
license. By installing, downloading, accessing, or otherwise using such
software upgrades, customers agree to follow the terms of the Cisco
software license: https://www.cisco.com/c/en/us/products/
end-user-license-agreement.html
Additionally, customers may only download software for which they have a
valid license, procured from Cisco directly, or through a Cisco authorized
reseller or partner. In most cases this will be a maintenance upgrade to
software that was previously purchased. Free security software updates do
not entitle customers to a new software license, additional software
feature sets, or major revision upgrades.
When considering software upgrades, customers are advised to regularly
consult the advisories for Cisco products, which are available from the
Cisco Security Advisories and Alerts page, 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.
Customers Without Service Contracts
Customers who purchase directly from Cisco but do not hold a Cisco service
contract and customers who make purchases through third-party vendors but
are unsuccessful in obtaining fixed software through their point of sale
should obtain upgrades by contacting the Cisco TAC: https://www.cisco.com/c
/en/us/support/web/tsd-cisco-worldwide-contacts.html
Customers should have the product serial number available and be prepared
to provide the URL of this advisory as evidence of entitlement to a free
upgrade.
Fixed Releases
Customers should upgrade to an appropriate release as indicated in the
following table:
???????????????????????????????????????????????????????????????????????
? Cisco Prime Infrastructure | First Fixed Release for This ?
? Major Release | Vulnerability ?
?---------------------------------+-----------------------------------?
? 3.2 | 3.3.1 Update 02 ?
?---------------------------------+-----------------------------------?
? 3.2 FIPS | No fix available^1 ?
?---------------------------------+-----------------------------------?
? 3.3 | 3.3.1 Update 02 ?
?---------------------------------+-----------------------------------?
? 3.4 | 3.4.1 ?
???????????????????????????????????????????????????????????????????????
1. TFTP is disabled by default in Cisco PI Release 3.2 FIPS. The
administrator can also use the workaround that is provided in this
advisory.
Software Download
Customers can download Cisco Prime Infrastructure Software from the
Software Center on Cisco.com by doing the following:
- Click Browse all.
- Navigate to Cloud and Systems Management > Routing and Switching
Management > Network Management Solutions > Prime Infrastructure.
- Access Cisco PI releases by using the right pane of the software
downloads navigation.
