Description

This security bulletin contains information about 13 secuirty vulnerabilities.


1) Cross-site scripting (CVE-ID: CVE-2019-11507)

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 on the Application Launcher page. 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.


2) Stack-based buffer over-read (CVE-ID: CVE-2018-19519)

The vulnerability allows a remote attacker to obtain potentially sensitive information or cause DoS condition.

The vulnerability exists in the print_prefix function, as defined in the print-hncp.c source code file of the affected software due to insufficient initialization of the buf variable. A remote attacker can trick the victim into execution of the tcpdumpcommand on a .pcap file that submits malicious input, trigger a stack-based buffer overread and access sensitive memory information or cause a DoS condition. 


3) Improper Authentication (CVE-ID: CVE-2020-8206)

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to an error in when processing authentication requests. A remote attacker can bypass the Google TOTP, if the primary credentials are exposed to attacker.


4) OS Command Injection (CVE-ID: CVE-2020-8218)

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

The vulnerability exists due to improper input validation in the admin panel. A remote authenticated user can pass specially crafted data to the application and execute arbitrary OS commands on the target system.

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


5) Path traversal (CVE-ID: CVE-2020-8221)

The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences in the admin panel. A remote user can send a specially crafted HTTP request and read arbitrary files on the system.


6) Path traversal (CVE-ID: CVE-2020-8222)

The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences in the admin interface. A remote user can send a specially crafted HTTP request and read arbitrary files on the system through Meeting.


7) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2020-8219)

The vulnerability allows a remote attacker to escalate privileges on the system.

The vulnerability exists due to application does not properly impose security restrictions, which leads to security restrictions bypass and privilege escalation. A user administrator can change the password of a full Administrator and escalate privileges on the system.


8) Command Injection (CVE-ID: CVE-2020-8220)

The vulnerability allows a remote user to perform a denial of service (DoS) attack.

The vulnerability exists due to improper input validation when processing user-supplied input within the administrator web interface. A remote authenticated user can perform command injection that causes denial of service.


9) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2020-12880)

The vulnerability allows a local attacker to escalate privileges on the system.

The vulnerability exists due to improper security restrictions. An attacker with physical access to the device can manipulate kernel boot parameter to gain the root access of VA Appliances.


10) Cross-site scripting (CVE-ID: CVE-2020-8204)

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 passed via URL to PSAL Page. 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.


11) Cross-site scripting (CVE-ID: CVE-2020-8217)

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 passed via URL used for Citrix ICA. 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.


12) Improper access control (CVE-ID: CVE-2020-8216)

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 user can discover find meeting details, if they know the Meeting ID.


13) Improper access control (CVE-ID: CVE-2020-15408)

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 user can access the admin panel of the device via the end user web interface through rewrite.
