Description

This security bulletin contains information about 9 secuirty vulnerabilities.


1) Out-of-bounds read (CVE-ID: CVE-2020-10037)

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

The vulnerability exists due to a boundary condition. A remote attacker can perform a flood attack against the web server, trigger out-of-bounds read error and read contents of memory on the system.


2) Missing Authentication for Critical Function (CVE-ID: CVE-2020-10038)

The vulnerability allows a remote attacker to execute arbitrary commands on the target system.

The vulnerability exists due missing authentication for critical function. A remote attacker with access to the device’s web server can execute administrative commands without authentication.


3) Missing Encryption of Sensitive Data (CVE-ID: CVE-2020-10039)

The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to missing encryption of sensitive data. A remote attacker in a privileged network position between a legitimate user and the web server can conduct a man-in-the-middle attack and gain read and write access to the transmitted data.


4) Use of Password Hash With Insufficient Computational Effort (CVE-ID: CVE-2020-10040)

The vulnerability allows a local attacker to access sensitive information on the target system.

The vulnerability exists due to usage of password hash with insufficient computational effort. A local attacker can retrieve passwords in clear text. 


5) Stored cross-site scripting (CVE-ID: CVE-2020-10041)

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 different locations of the web application. A remote attacker can inject 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.


6) Buffer overflow (CVE-ID: CVE-2020-10042)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error. A remote attacker can trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


7) Cross-site scripting (CVE-ID: CVE-2020-10043)

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. 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.


8) Missing Authentication for Critical Function (CVE-ID: CVE-2020-10044)

The vulnerability allows a remote attacker to compromise the targte system.

The vulnerability exists due missing authentication for critical function. A remote attacker can install specially crafted firmware on the device.


9) Authentication Bypass by Capture-replay (CVE-ID: CVE-2020-10045)

The vulnerability allows a remote attacker to bypass authentication on the target system.

The vulnerability exists due to improper authentication process. A remote attacker can replay authentication traffic and gain access to protected areas of the web application.
