# INDAS Web SCADA Path Traversal Vulnerability
#


### OVERVIEW

Independent researcher Ehab Hussein of IOActive has identified a path traversal vulnerability in the INDAS Web SCADA application. INDAS has produced new software to mitigate this vulnerability.

This vulnerability could be exploited remotely.




### AFFECTED PRODUCTS

The following INDAS Web SCADA versions are affected:

Web SCADA, versions prior to Version 3






### IMPACT

Successful exploitation of this vulnerability could allow an attacker to download arbitrary files from the target system.

Impact to individual organizations depends on many factors that are unique to each organization. NCCIC/ICS-CERT recommends that organizations evaluate the impact of this vulnerability based on their operational environment, architecture, and product implementation.






### BACKGROUND

INDAS is a Serbia-based company that does not maintain offices in other countries.

The affected product, Web SCADA, is a web-based SCADA system. According to INDAS, Web SCADA is deployed across several sectors including Communications, and Water and Wastewater Systems. INDAS estimates that this product is used primarily in Serbia.





### VULNERABILITY CHARACTERIZATION


# VULNERABILITY OVERVIEW


PATH TRAVERSAL

External input is used to construct paths to files and directories without properly neutralizing special elements within the pathname that could allow an attacker to read arbitrary files on the system.
CVE-2016-8343 has been assigned to this vulnerability. A CVSS v3 base score of 10.0 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:N).






### VULNERABILITY DETAILS


# EXPLOITABILITY

This vulnerability could be exploited remotely.


# EXISTENCE OF EXPLOIT

No known public exploits specifically target this vulnerability.


# DIFFICULTY

An attacker with a low skill would be able to exploit this vulnerability.





### MITIGATION

INDAS has produced new software, InView SCADA, that replaces Web SCADA. INDAS recommends users contact an INDAS sales representative to procure the new software.

ICS-CERT recommends that users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should:

* Minimize network exposure for all control system devices and/or systems, and ensure that they are not accessible from the Internet.

* Locate control system networks and remote devices behind firewalls, and isolate them from the business network.

* When remote access is required, use secure methods, such as Virtual Private Networks (VPNs), recognizing that VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize that VPN is only as secure as the connected devices.
