Description
This security bulletin contains information about 10 secuirty vulnerabilities.
1) Improper Authentication (CVE-ID: CVE-2020-13927)
The vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to default setting for Airflow's Experimental API allow all API requests to be performed without authentication. A remote non-authenticated attacker can perform arbitrary API actions and eventually compromise the affected system.
2) Insecure Default Variable Initialization (CVE-ID: CVE-2020-11982)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to the affected software, by default, initializes an internal variable with an insecure or less secure value than is possible. A remote authenticated attacker who can connect to the broker (Redis, RabbitMQ) directly can pass specially crafted data to the application and execute arbitrary code on the target system.
3) OS Command Injection (CVE-ID: CVE-2020-11981)
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 "celery" executor. A remote authenticated attacker 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) Information disclosure (CVE-ID: CVE-2021-35936)
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 attacker can gain unauthorized access to sensitive information on the system.
5) Cross-site scripting (CVE-ID: CVE-2021-28359)
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 "origin" parameter. 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) Cross-site scripting (CVE-ID: CVE-2020-13944)
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 the "origin" parameter to several URLs, such as "/tigger" URL. 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.
7) Cross-site scripting (CVE-ID: CVE-2020-17515)
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.
Note, this vulnerability exists due to incomplete fix for previous issue #VU46772.
8) Input validation error (CVE-ID: CVE-2021-23336)
The vulnerability allows a remote attacker to perform web cache spoofing attack.
The vulnerability exists due to insufficient validation of user-supplied input in django.utils.http.limited_parse_qsl() when parsing strings with a semicolon (";"). A remote attacker can pass specially crafted data to the application and perform a spoofing attack.
9) Use of hard-coded credentials (CVE-ID: CVE-2020-17526)
The vulnerability allows a remote attacker to gain full access to vulnerable application.
The vulnerability exists due to Apache Airflow relies on session management based on the default [webserver] secret_key value. A remote attacker, who successfully authenticated at one website can re-use the same session to authenticate on another unrelated website, if both web servers are configured with the default [webserver] secret_key value.
10) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2020-17513)
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.
Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.
