CVE-2021-39223 (GCVE-0-2021-39223)

Vulnerability from cvelistv5

Published

2021-10-25 21:35

Modified

2024-08-04 01:58

Severity ?

4.8 (Medium) - CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:N/A:N

CWE

CWE-200 - Exposure of Sensitive Information to an Unauthorized Actor

Summary

Nextcloud is an open-source, self-hosted productivity platform. The Nextcloud Richdocuments application prior to versions 3.8.6 and 4.2.3 returned verbatim exception messages to the user. This could result in a full path disclosure on shared files. (e.g. an attacker could see that the file `shared.txt` is located within `/files/$username/Myfolder/Mysubfolder/shared.txt`). It is recommended that the Richdocuments application is upgraded to 3.8.6 or 4.2.3. As a workaround, disable the Richdocuments application in the app settings.
