Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Information disclosure (CVE-ID: CVE-2021-20656)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application. A remote authenticated attacker on the local network can gain unauthorized access to sensitive information on the system.
2) Improper access control (CVE-ID: CVE-2021-20657)
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 on the local network can obtain and alter the setting information without the access privileges.
3) OS Command Injection (CVE-ID: CVE-2021-20658)
The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.
The vulnerability exists due to improper input validation. A remote attacker on the local network 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.
4) Arbitrary file upload (CVE-ID: CVE-2021-20659)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to insufficient validation of file during file upload. A remote authenticated attacker on the local network can upload a malicious file and execute it on the server.
5) Cross-site scripting (CVE-ID: CVE-2021-20660)
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.
6) Path traversal (CVE-ID: CVE-2021-20661)
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences. A remote authenticated attacker on the local network can send a specially crafted HTTP request and delete arbitrary files on the server.
7) Missing Authentication for Critical Function (CVE-ID: CVE-2021-20662)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to missing authentication. A remote attacker on the local network can alter the setting information without the access privileges
