Title
Reflected Cross-Site Scripting (XSS) vulnerability in Graylog Web Interface
Summary
Reflected Cross-Site Scripting (XSS) vulnerability in the Graylog Web Interface console, version 2.2.3, caused by a lack of proper sanitization and escaping in HTML output. Several endpoints include segments of the URL directly in the response without applying output encoding, allowing an attacker to inject and execute arbitrary JavaScript code when a user visits a specially crafted URL. Exploitation of this vulnerability may allow script execution in the victim's browser and limited manipulation of the affected user's session context, through the '/system/index_sets/' endpoint.
Severity ?
CWE
- CWE-79 - Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting')

Title
Improper Access Control (IDOR) vulnerability in Graylog Web Interface
Summary
Improper Access Control (IDOR) in the Graylog API, version 2.2.3, which occurs when modifying the user ID in the URL. An authenticated user can access other user's profiles without proper authorization checks. Exploiting this vulnerability allows valid users of the system to be listed and sensitive third-party information to be accessed, such as names, email addresses, internal identifiers, and last activity. The endpoint 'http://<IP>:12900/users/<my_user>' does not implement object-level authorization validations.

Title
Incorrect management of session invalidation vulnerability in Graylog Web Interface
Summary
Not properly invalidated session vulnerability in Graylog Web Interface, version 2.2.3, due to incorrect management of session invalidation after new logins. The application generates a new 'sessionId' each time a user authenticates, but does not invalidate previously issued session identifiers, which remain valid even after multiple consecutive logins by the same user. As a result, a stolen or leaked 'sessionId' can continue to be used to authenticate valid requests. Exploiting this vulnerability would allow an attacker with access to the web service/API network (port 9000 or HTTP/S endpoint of the server) to reuse an old session token to gain unauthorized access to the application, interact with the API/web, and compromise the integrity of the affected account.
