TITLE

Trihedral VTScada Denial of service vulnerability

Trust: 0.8

sources: IVD: a084bafc-df0b-469d-85a8-46c98d18dce9 // CNVD: CNVD-2017-10707

DESCRIPTION

A Resource Consumption issue was discovered in Trihedral VTScada Versions prior to 11.2.26. The client does not properly validate the input or limit the amount of resources that are utilized by an attacker, which can be used to consume more resources than are available. Trihedral VTScada Contains a resource exhaustion vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. Trihedral VTScada (formerly known as VTS) is a SCADA system based on the Windows platform provided by Trihedral Engineering of Canada. A denial of service vulnerability exists in versions of Trihedral VTScada prior to 11.2.26 that caused the program to fail to validate input or limit the total amount of resources used. An attacker could exploit the vulnerability to cause a denial of service (a significant drain on resources). Trihedral VTScada is prone to multiple security vulnerabilities: 1. A denial-of-service vulnerability. 2. A cross-site scripting vulnerability. 3. An information-disclosure vulnerability. An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This can allow the attacker to steal cookie-based authentication credentials or gain access to sensitive information. Failed exploit attempts will likely result in denial-of-service conditions. Vendor: Trihedral Equipment: VTScada Vulnerability: Resource Consumption, Cross-Site Scripting, Information Exposure Advisory URL: https://ipositivesecurity.com/2017/06/15/ics-trihedral-vtscada-multiple-vulnerabilities/ ICS-CERT Advisory https://ics-cert.us-cert.gov/advisories/ICSA-17-164-01 ------------------------ AFFECTED PRODUCTS ------------------------ The following versions of VTScada, an HMI SCADA software, are affected: VTScada Versions prior to 11.2.26 ------------------------ IMPACT ------------------------ Successful exploitation of these vulnerabilities could result in uncontrolled resource consumption, arbitrary code execution, or information exposure. A CVSS v3 base score of 7.5 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H <https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H> ). Exploitation Note that this vulnerability targets the VTScada thick client installed on the system. Any application user (including a non-admin, restricted user) who has access to the thick client can potentially bring down the system. Payload can be up to ~80k characters. Repeated attempts result in spiked CPU usage & consumption of RAM / page resources. Where a full-blown application (or multiple applications in production scenario) is deployed, i.e. with an operational/functional configuration, memory/CPU usage is notably higher than that of a test, blank application. Repeatedly submitting such a large username input, rapidly consumes available server memory resources leading to resource exhaustion. This forces a system reboot eventually. Where an endpoint security solution (such as AV/HIPS/Anti-Malware) is deployed on the system, resource exhaustion may be achieved relatively much faster (quickly). A CVSS v3 base score of 6.5 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N <https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N> ). Exploitation Multiple URLs and parameters were found to vulnerable to Reflected Cross-Site Scripting. INFORMATION EXPOSURE CWE-548 <https://cwe.mitre.org/data/definitions/548.html> Some files are exposed within the web server application to unauthenticated users. These files may contain sensitive configuration information. A CVSS v3 base score of 7.5 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N <https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N> )
