CVE-2023-23934
2.6 · LOWOverview
CVE-2023-23934 is a low-severity vulnerability affecting palletsprojects werkzeug. It was published on February 14, 2023 and has a CVSS 3.1 base score of 2.6 (LOW).
This vulnerability has a CVSS 3.1 base score of 2.6, rated LOW. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
Werkzeug is a comprehensive WSGI web application library. Browsers may allow "nameless" cookies that look like `=value` instead of `key=value`. A vulnerable browser may allow a compromised application on an adjacent subdomain to exploit this to set a cookie like `=__Host-test=bad` for another subdomain. Werkzeug prior to 2.2.3 will parse the cookie `=__Host-test=bad` as __Host-test=bad`. If a Werkzeug application is running next to a vulnerable or malicious subdomain which sets such a cookie using a vulnerable browser, the Werkzeug application will see the bad cookie value but the valid cookie key. The issue is fixed in Werkzeug 2.2.3.
Remediation
Check the references section for vendor advisories and patches from palletsprojects. Update werkzeug to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
