Description
This security bulletin contains information about 17 secuirty vulnerabilities.
1) Use of hard-coded credentials (CVE-ID: CVE-2022-1162)
The vulnerability allows a remote attacker to gain full access to vulnerable system.
The vulnerability exists due to presence of hard-coded credentials in application code within the OmniAuth-based registration. A remote unauthenticated attacker can access the affected system using the hard-coded credentials.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Input validation error (CVE-ID: CVE-2022-1185)
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 user can send a specially crafted RDoc file and perform a denial of service (DoS) attack.
3) Stored cross-site scripting (CVE-ID: CVE-2022-1190)
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 Multi-word milestone reference. 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.
4) Information disclosure (CVE-ID: CVE-2022-1120)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to missing filtering in an error message. A remote user can gain unauthorized access to sensitive information when an include directive fails in the CI/CD configuration.
5) Input validation error (CVE-ID: CVE-2022-1100)
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 release asset link. A remote user can pass specially crafted input to the application and perform a denial of service (DoS) attack.
6) Improper access control (CVE-ID: CVE-2022-1193)
The vulnerability allows a remote attacker to gain unauthorized access to sensitive information.
The vulnerability exists due to improper access restrictions. A remote user can obtain details of the latest commit in a private project via Merge Requests.
7) Improper access control (CVE-ID: CVE-2022-1105)
The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper access restrictions. A remote user can bypass implemented security restrictions and access pipeline analytics even when public pipelines are disabled.
8) Input validation error (CVE-ID: CVE-2022-1099)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to absence of limit for the number of tags that can be added to a runner. A remote user can pass specially crafted input to the application and perform a denial of service (DoS) attack.
9) Input validation error (CVE-ID: CVE-2022-1174)
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 Issues, Merge requests, Milestones, Snippets, Wiki pages, etc. A remote user can pass specially crafted input to the application and perform a denial of service (DoS) attack.
10) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2022-1188)
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input in the repository mirroring feature. 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.
11) Improper Authorization (CVE-ID: CVE-2022-0740)
The vulnerability allows a remote attacker to bypass authorization checks.
The vulnerability exists due to incorrect authorization in the Asana integration's branch restriction feature. A remote user can close Asana tasks from unrestricted branches.
12) Information disclosure (CVE-ID: CVE-2022-1189)
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 user can read the the approval rules of a private project.
13) Information disclosure (CVE-ID: CVE-2022-1157)
The vulnerability allows a remote user to gain access to potentially sensitive information.
The vulnerability exists due to missing sanitization of logged exception messages. A remote administrator can gain unauthorized access to sensitive information on the system.
14) Business Logic Errors (CVE-ID: CVE-2022-1111)
The vulnerability allows a remote user to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to a business logic error in Project Import. A remote administrator can cause imported projects to show an incorrect user in the "Access Granted" column in the project membership pages.
15) Improper Authorization (CVE-ID: CVE-2022-1148)
The vulnerability allows a remote attacker to bypass authorization checks.
The vulnerability exists due to incorrect authorization in GitLab Pages. A remote attacker can steal a user's access token on an attacker-controlled private GitLab Pages website.
16) Input validation error (CVE-ID: CVE-2022-1121)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a lack of appropriate timeouts in GitLab Pages. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
17) Stored cross-site scripting (CVE-ID: CVE-2022-1175)
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 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.
