Description

This security bulletin contains information about 1 vulnerability.


1) OS Command Injection (CVE-ID: CVE-2026-35582)

CWE-ID: CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to execute arbitrary os commands.

The vulnerability exists due to improper neutralization of special elements used in an os command in Executrix.getCommand() and TempFileNames when constructing a /bin/sh -c command with unvalidated IN_FILE_ENDING or OUT_FILE_ENDING values. A local user can supply specially crafted file ending values to execute arbitrary os commands.

The issue is triggered when a configured place processes a payload, and it also affects the String[] getCommand() overload used by MultiFileUnixCommandPlace.
