Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Stored cross-site scripting (CVE-ID: CVE-2021-39946)
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 notes. A remote authenticated 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.
2) Cross-site request forgery (CVE-ID: CVE-2022-0154)
The vulnerability allows a remote attacker to perform cross-site request forgery attacks.
The vulnerability exists due to lack of state parameter on GitHub import project OAuth. A remote authenticated attacker can trick the victim to visit a specially crafted web page and perform arbitrary actions on behalf of the victim on the vulnerable website.
3) Information disclosure (CVE-ID: CVE-2022-0152)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to unauthorized access to some particular fields through the GraphQL API. A remote authenticated attacker can gain unauthorized access to sensitive information on the system.
4) Input validation error (CVE-ID: CVE-2022-0151)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper handling of requests to delete existing packages. A remote administrator can pass specially crafted input to the application and perform a denial of service (DoS) attack.
5) Information disclosure (CVE-ID: CVE-2022-0172)
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 bypass the IP restriction for public projects through GraphQL and gain unauthorized access to sensitive information on the system.
6) Spoofing attack (CVE-ID: CVE-2022-0090)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to incorrect processing of user-supplied data when using Git replacement references. A remote authenticated attacker can spoof page content.
7) Information disclosure (CVE-ID: CVE-2022-0125)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to improper verify that a maintainer of a project has the right access to import members from a target project. A remote authenticated attacker can gain unauthorized access to sensitive information on the system.
8) Open redirect (CVE-ID: CVE-2022-0124)
The vulnerability allows a remote attacker to redirect victims to arbitrary URL.
The vulnerability exists due to improper sanitization of user-supplied data in the Slack integration. A remote authenticated attacker can create a link that leads to a trusted website, however, when clicked, redirects the victim to arbitrary domain.
Successful exploitation of this vulnerability may allow a remote attacker to perform a phishing attack and steal potentially sensitive information.
9) Input validation error (CVE-ID: CVE-2021-39942)
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. A remote authenticated attacker can bypass file size limits in the NPM package repository and perform a denial of service (DoS) attack.
10) Insufficient Session Expiration (CVE-ID: CVE-2022-0093)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient session expiration issue. A remote authenticated attacker with an expired password can access sensitive information through RSS feeds.
11) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2021-39927)
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input. A remote authenticated 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.
12) Information disclosure (CVE-ID: N/A)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to incorrect file handling. A remote attacker can import a group and gain unauthorized access to sensitive information on the system.
