Denial of Service attack on windows app using Netty

CVE-2025-25193 / GHSA-389x-839f-4rhx

More information

Details

Summary

An unsafe reading of environment file could potentially cause a denial of service in Netty.
When loaded on an Windows application, Netty attemps to load a file that does not exist. If an attacker creates such a large file, the Netty application crash.

Details

A similar issue was previously reported in GHSA-xq3w-v528-46rv
This issue was fixed, but the fix was incomplete in that null-bytes were not counted against the input limit.

PoC

The PoC is the same as for GHSA-xq3w-v528-46rv with the detail that the file should only contain null-bytes; 0x00.
When the null-bytes are encountered by the InputStreamReader, it will issue replacement characters in its charset decoding, which will fill up the line-buffer in the BufferedReader.readLine(), because the replacement character is not a line-break character.

Impact

Impact is the same as GHSA-xq3w-v528-46rv

Severity

• CVSS Score: 5.5 / 10 (Medium)
• Vector String: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
