Detailsinfo

A vulnerability, which was classified as problematic, has been found in Jupyter Server 2.11.2. Affected by this issue is an unknown code block of the component API. The manipulation with an unknown input leads to a information exposure vulnerability. Using CWE to declare the problem leads to CWE-209. The product generates an error message that includes sensitive information about its environment, users, or associated data. Impacted is confidentiality. CVE summarizes:

The Jupyter Server provides the backend (i.e. the core services, APIs, and REST endpoints) for Jupyter web applications like Jupyter notebook, JupyterLab, and Voila. Unhandled errors in API requests coming from an authenticated user include traceback information, which can include path information. There is no known mechanism by which to trigger these errors without authentication, so the paths revealed are not considered particularly sensitive, given that the requesting user has arbitrary execution permissions already in the same environment. A fix has been introduced in commit `0056c3aa52` which no longer includes traceback information in JSON error responses. For compatibility, the traceback field is present, but always empty. This commit has been included in version 2.11.2. Users are advised to upgrade. There are no known workarounds for this vulnerability.

The weakness was presented 12/05/2023 as GHSA-h56g-gq9v-vc8r. The advisory is available at github.com. This vulnerability is handled as CVE-2023-49080 since 11/21/2023. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1592 by the MITRE ATT&CK project.

Upgrading to version 2.11.2 eliminates this vulnerability. Applying the patch 0056c3aa52cbb28b263a7a609ae5f17618b36652 is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.
