CVE-2022-21230 (GCVE-0-2022-21230)

Vulnerability from cvelistv5 – Published: 2022-05-01 15:20 – Updated: 2024-09-16 23:31

Title

Information Exposure

Summary

This affects all versions of package org.nanohttpd:nanohttpd. Whenever an HTTP Session is parsing the body of an HTTP request, the body of the request is written to a RandomAccessFile when the it is larger than 1024 bytes. This file is created with insecure permissions that allow its contents to be viewed by all users on the host machine. **Workaround:** Manually specifying the -Djava.io.tmpdir= argument when launching Java to set the temporary directory to a directory exclusively controlled by the current user can fix this issue.

Severity ?

5.5 (Medium)
