Description

This security bulletin contains information about 18 secuirty vulnerabilities.


1) Improper access control (CVE-ID: CVE-2019-6791)

The vulnerability allows a remote attacker to gain unauthorized access to sensitive information.

The vulnerability exists due to improper access restrictions. A remote attacker can send a specially crafted request and gain unauthorized access to the affected application.


2) Information disclosure (CVE-ID: CVE-2019-6782)

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

An issue was discovered in GitLab Community and Enterprise Edition before 11.5.8, 11.6.x before 11.6.6, and 11.7.x before 11.7.1. It allows Information Disclosure (issue 1 of 6). An authorization issue allows the contributed project information of a private profile to be viewed.


3) Path traversal (CVE-ID: CVE-2019-6783)

The vulnerability allows a remote authenticated user to execute arbitrary code.

An issue was discovered in GitLab Community and Enterprise Edition before 11.5.8, 11.6.x before 11.6.6, and 11.7.x before 11.7.1. GitLab Pages contains a directory traversal vulnerability that could lead to remote command execution.


4) Cross-site scripting (CVE-ID: CVE-2019-6784)

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.


5) Input validation error (CVE-ID: CVE-2019-6785)

The vulnerability allows a remote authenticated user to perform a denial of service (DoS) attack.

An issue was discovered in GitLab Community and Enterprise Edition before 11.5.8, 11.6.x before 11.6.6, and 11.7.x before 11.7.1. It allows Denial of Service. Inputting an overly long string into a Markdown field could cause a denial of service.


6) Improper access control (CVE-ID: CVE-2019-6786)

The vulnerability allows a remote attacker to gain unauthorized access to sensitive information.

The vulnerability exists due to improper access restrictions. A remote attacker can send a specially crafted request and gain unauthorized access to the affected application.


7) Information disclosure (CVE-ID: CVE-2019-6788)

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

An issue was discovered in GitLab Community and Enterprise Edition before 11.5.8, 11.6.x before 11.6.6, and 11.7.x before 11.7.1. It allows Information Disclosure (issue 3 of 6). For installations using GitHub or Bitbucket OAuth integrations, it is possible to use a covert redirect to obtain the user OAuth token for those services.


8) Information disclosure (CVE-ID: CVE-2019-6789)

The vulnerability allows a remote authenticated user to gain access to sensitive information.

An issue was discovered in GitLab Community and Enterprise Edition before 11.5.8, 11.6.x before 11.6.6, and 11.7.x before 11.7.1. It allows Information Disclosure (issue 4 of 6). In some cases, users without project permissions will receive emails after a project move. For private projects, this will disclose the new project namespace to an unauthorized user.


9) Information disclosure (CVE-ID: CVE-2019-6792)

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

An issue was discovered in GitLab Community and Enterprise Edition before 11.5.8, 11.6.x before 11.6.6, and 11.7.x before 11.7.1. It allows Path Disclosure. When an error is encountered on project import, the error message will display instance internal information.


10) Information disclosure (CVE-ID: CVE-2019-6794)

The vulnerability allows a remote authenticated user to gain access to sensitive information.

An issue was discovered in GitLab Community and Enterprise Edition before 11.5.8, 11.6.x before 11.6.6, and 11.7.x before 11.7.1. It allows Information Disclosure (issue 5 of 6). A project guest user can view the last commit status of the default branch.


11) Input validation error (CVE-ID: CVE-2019-6795)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

An issue was discovered in GitLab Community and Enterprise Edition before 11.5.8, 11.6.x before 11.6.6, and 11.7.x before 11.7.1. It has Insufficient Visual Distinction of Homoglyphs Presented to a User. IDN homographs and RTLO characters are rendered to unicode, which could be used for social engineering.
