Description
This security bulletin contains information about 15 secuirty vulnerabilities.
1) Business Logic Errors (CVE-ID: CVE-2022-2455)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a business logic issue in the handling of large repositories. A remote user can pass specially crafted input to the application and perform a denial of service (DoS) attack.
2) Weak password requirements (CVE-ID: CVE-2022-3031)
The vulnerability allows a remote attacker to perform brute-force attack and guess the password.
The vulnerability exists due to weak password requirements even when 2FA is enabled. A remote attacker can perform a brute-force attack and guess users' passwords.
3) Information disclosure (CVE-ID: CVE-2022-2907)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to the possibility to read repository content via LivePreview feature. A remote user can gain unauthorized access to sensitive information on the system.
4) Input validation error (CVE-ID: CVE-2022-2931)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in the Commit message field. A remote user can pass specially crafted input to the application and perform a denial of service (DoS) attack.
5) Improper access control (CVE-ID: CVE-2022-2630)
The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper access restrictions in Incident Timeline Events. A remote user can bypass implemented security restrictions and gain unauthorized access to sensitive information on the system.
6) Input validation error (CVE-ID: CVE-2022-2908)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in the Commit message field. A remote user can pass specially crafted input to the application and perform a denial of service (DoS) attack.
7) Input validation error (CVE-ID: CVE-2022-2428)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to arbitrary HTTP requests possible in .ipynb Notebook with malicious Form Tags. A remote user can use a specially crafted tag in the Jupyter Notebook viewer to issue arbitrary HTTP requests.
8) Improper Authentication (CVE-ID: CVE-2022-2533)
The vulnerability allows a remote user to bypass authentication process.
The vulnerability exists due to improper authentication with some Package Registries when IP address restrictions were configured. A remote administrator can misuse it from any location.
9) Input validation error (CVE-ID: CVE-2022-2592)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a lack of length validation in Snippet descriptions. A remote user can pass specially crafted input to the application and perform a denial of service (DoS) attack.
10) Input validation error (CVE-ID: CVE-2022-2527)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to the content injection issue via Incidents Timeline description. A remote user can inject arbitrary content on the system.
11) Stored cross-site scripting (CVE-ID: CVE-2022-2865)
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 setting the labels colour feature. A remote user 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.
12) Command Injection (CVE-ID: CVE-2022-2992)
The vulnerability allows a remote attacker to execute arbitrary commands on the target system.
The vulnerability exists due to improper input validation within the Import from GitHub API endpoint. A remote user can pass specially crafted data to the application and execute arbitrary commands on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
13) Input validation error (CVE-ID: N/A)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input within the Issue preview. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
14) Input validation error (CVE-ID: N/A)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in the Create branch API. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
15) Information disclosure (CVE-ID: N/A)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to an insecure direct object reference (IDOR) issue in Zentao integration. A remote user can gain unauthorized access to sensitive information on the system.
