Description

This security bulletin contains information about 7 secuirty vulnerabilities.


1) Improper handling of case sensitivity (CVE-ID: CVE-2025-46701)

The vulnerability allows a remote attacker to bypass security restrictions.

The vulnerability exists due to an error when handling URLs on a case insensitive filesystem with security constraints configured for the <code>pathInfo</code> component of a URL that mapped to the CGI servlet. A remote attacker can bypass imposed security constraints via a specially crafted URL.


2) Resource exhaustion (CVE-ID: CVE-2024-54677)

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

The vulnerability exists due to the examples web application does not properly control consumption of internal resources. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


3) Input validation error (CVE-ID: CVE-2025-31651)

The vulnerability allows a remote attacker to bypass rewrite rules.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can send a specially crafted input to the application and bypass configured rewrite rules.


4) Improper error handling (CVE-ID: CVE-2025-31650)

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

The vulnerability exists due to insufficient error handling for certain invalid HTTP priority headers. A remote attacker can send a large amount of specially crafted HTTP requests to the server and consume all available memory, resulting in a denial of service condition.


5) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2024-50379)

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

The vulnerability exists due to missing access restrictions to the default servlet. If the default servlet is write enabled (readonly initialisation parameter set to the non-default value of false) for a case insensitive file system, concurrent read and upload under load of the same file can bypass Tomcat's case sensitivity checks and cause an uploaded file to be treated as a JSP leading to remote code execution.


6) Improper Authentication (CVE-ID: CVE-2024-52316)

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to an error when processing authentication requests. If Tomcat was configured to use a custom Jakarta Authentication (formerly JASPIC) ServerAuthContext component which may throw an exception during the authentication process without explicitly setting an HTTP status to indicate failure, the authentication may not have failed, allowing the user to bypass the authentication process.


7) Resource management error (CVE-ID: CVE-2024-52317)

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

The vulnerability exists due to improper management of internal resources when handling HTTP/2 responses, which causes request and/or response mix-up between users. A remote non-authenticated attacker can send a series of HTTP/2 requests and gain access to sensitive information.
