Description

This security bulletin contains information about 10 secuirty vulnerabilities.


1) Improper access control (CVE-ID: CVE-2020-26080)

The vulnerability allows a remote user to gain unauthorized access to otherwise restricted functionality.

The vulnerability exists due to improper access restrictions. A remote administrator can manipulate JSON payloads and manage user information for users in different domains.


2) Cross-site scripting (CVE-ID: CVE-2020-26081)

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data in the web UI. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.


3) Information disclosure (CVE-ID: CVE-2020-26076)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to the absence of authentication for sensitive information. A remote attacker can send specially crafted curl commands and gain unauthorized access to sensitive information on the system.


4) Unprotected storage of credentials (CVE-ID: CVE-2020-26079)

The vulnerability allows a remote user to gain access to other users' credentials.

The vulnerability exists due to application stored credentials in plain text in a configuration file on the system. A remote administrator can view contents of the configuration file and gain access to passwords for 3rd party integration.


5) External Control of File Name or Path (CVE-ID: CVE-2020-26078)

The vulnerability allows a remote user to overwrite files on an affected system.

The vulnerability exists due to insufficient file system protections. A remote administrator can send specially crafted API requests and overwrite files on the target system.


6) Improper access control (CVE-ID: CVE-2020-26077)

The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.

The vulnerability exists due to improper access restrictions. A remote authenticated attacker can send an API request and view lists of users from different domains on the affected system.


7) Improper access control (CVE-ID: CVE-2020-26072)

The vulnerability allows a remote user to gain unauthorized access to otherwise restricted functionality.

The vulnerability exists due to improper access restrictions in the SOAP API. A remote administrator can send SOAP API requests to access and modify information on devices that belong to a different domain.


8) Missing Authentication for Critical Function (CVE-ID: CVE-2020-3531)

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to the affected system does not properly authenticate API calls. A remote attacker can obtain a cross-site request forgery (CSRF) token, then use the token with REST API requests, access the back-end database of the affected device and read, alter, or drop information.


9) Missing Authentication for Critical Function (CVE-ID: CVE-2020-3392)

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to the affected system does not properly authenticate API calls. A remote attacker can send API requests and view sensitive information on the target system without authentication.


10) SQL injection (CVE-ID: CVE-2020-26075)

The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.

The vulnerability exists due to insufficient sanitization of user-supplied data in the REST API. A remote authenticated attacker can send a specially crafted request to the affected application and gain access to the back-end database of the affected device.
