CVE-2024-34069
Description
A flaw was found in Werkzeug, where an attacker may be able to execute code on a developer's machine under some circumstances. This issue requires the attacker to get the developer to interact with a domain and subdomain they control and enter the debugger PIN; if they are successful, it allows access to the debugger even if it is only running on localhost. This also requires the attacker to guess a URL in the developer's application that will trigger the debugger.
Statement
Werkzeug's debugger allows an attacker to potentially execute code on a developer's machine. This can occur if the attacker tricks the developer into interacting with a controlled domain and subdomain and entering the debugger PIN. Although the debugger is meant to run locally, successful exploitation can give the attacker access to it by guessing a specific URL that triggers the debugger. The severity is rate as IMPORTANT because this flaw can potentially impacts confidentiality, integrity, and availability if the attacker can gain control.
Ceph uses an affected Werkzeug version but this vulnerability does not impact OpenShift Data Foundation (ODF) because the debugger is not set up or used on development machines, so there is no debugger to have information taken from.
Mitigation
Red Hat has investigated whether a possible mitigation exists for this issue, and has not been able to identify a practical example. Please update the affected package as soon as possible.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Technical Impact: Gain Privileges or Assume Identity; Bypass Protection Mechanism; Read Application Data; Modify Application Data; DoS: Crash, Exit, or Restart
The consequences will vary depending on the nature of the functionality that is vulnerable to CSRF. An attacker could trick a client into making an unintentional request to the web server via a URL, image load, XMLHttpRequest, etc., which would then be treated as an authentic request from the client - effectively performing any operations as the victim, leading to an exposure of data, unintended code execution, etc. If the victim is an administrator or privileged user, the consequences may include obtaining complete control over the web application - deleting or stealing data, uninstalling the product, or using it to launch other attacks against all of the product's users. Because the attacker has the identity of the victim, the scope of CSRF is limited only by the victim's privileges.
