Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) Resource exhaustion (CVE-ID: CVE-2023-26048)

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

The vulnerability exists due to application does not properly control consumption of internal resources when processing multipart requests in request.getParameter(). A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


2) Input validation error (CVE-ID: CVE-2023-26049)

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

The vulnerability exists due to insufficient input validation when parsing cookies. A remote attacker can send a specially crafted HTTP request with a cookie value that starts with a double quote and force the application to read the cookie string until it sees a closing quote. Such behavior can be used to exfiltrate sensitive values from other cookies.


3) Input validation error (CVE-ID: CVE-2023-36479)

The vulnerability allows a remote user to compromise the affected system.

The vulnerability exists due to insufficient validation of user-supplied input in org.eclipse.jetty.servlets.CGI Servlet when quoting a command before its execution. A remote user can force the application to execute arbitrary file on the server and potentially compromise the system.


4) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2023-40167)

The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.

The vulnerability exists due to improper validation of HTTP requests when handling the "+" character passed via the HTTP/1 header field. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.

Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.


5) Improper Authorization (CVE-ID: CVE-2023-41900)

The vulnerability allows a remote user to bypass implemented security restrictions.

The vulnerability exists due to an error in the revocation process. If a Jetty OpenIdAuthenticator uses the optional nested LoginService, and that LoginService decides to revoke an already authenticated user, then the current request will still treat the user as authenticated.
