CVE-2024-34069: Werkzeug's improper usage of a pathname and improper CSRF protection results in the remote command execution

Noroxi assessment

Priority: This week (action score 60/100)

  • A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
  • A ready-made attack tool exists and the flaw can be exploited over the network without an account, so priority is at least “This week”.
  • Probability of exploitation in the next 30 days: 3.3% (FIRST EPSS); higher than 88.8% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. Special conditions such as timing or configuration are required.
  • Fixed version: pallets werkzeug 3.0.3; azl3 python-werkzeug 3.0.1-1 on Azure Linux 3.0 3.0.3-1; azl3 python-werkzeug 3.0.3-1 on Azure Linux 3.0 3.0.3-1.

Don’t wait for the next maintenance window. Upgrade to pallets werkzeug 3.0.3; azl3 python-werkzeug 3.0.1-1 on Azure Linux 3.0 3.0.3-1; azl3 python-werkzeug 3.0.3-1 on Azure Linux 3.0 3.0.3-1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

Werkzeug is a comprehensive WSGI web application library. The debugger in affected versions of Werkzeug can allow an attacker to execute code on a developer's machine under some circumstances. This requires the attacker to get the developer to interact with a domain and subdomain they control, and enter the debugger PIN, but 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. This vulnerability is fixed in 3.0.3.
