OS command injection in the environment and tunnel configuration functionality in SIMA GmbH Bondix through version 1.25.7.5 on Linux allows an authenticated attacker with configuration write access to execute arbitrary operating-system commands via crafted configuration values passed to server-side scripts.
AnalysisAI
Authenticated OS command injection in SIMA GmbH Bondix Server through 1.25.7.5 on Linux allows an attacker with configuration write privileges to execute arbitrary operating-system commands by supplying crafted values in the environment and tunnel configuration that are passed unsanitized to server-side scripts. The flaw was reported by NCSC.ch and carries a CVSS 4.0 base score of 8.6 (High); no public exploit identified at time of analysis, and the vulnerability is not listed in CISA KEV.
Technical ContextAI
Bondix Server is a Linux-based management/orchestration service from SIMA GmbH whose environment and tunnel configuration subsystems accept operator-supplied values that are later interpolated into server-side shell scripts. The root cause is CWE-78 (Improper Neutralization of Special Elements used in an OS Command), meaning configuration strings reach a shell interpreter without proper escaping or argument-array invocation, so metacharacters such as ';', '|', '$()' or backticks break out of the intended command. The affected CPE is cpe:2.3:a:sima_gmbh:bondix_server:*:*:*:*:*:*:*:* covering all releases up to and including 1.25.7.5.
RemediationAI
Upgrade Bondix Server to the fixed release identified in the vendor advisory at https://wiki.bondix.dev/wiki/Security_Advisories#CVE-2026-12104_%E2%80%94_Authenticated_OS_Command_Injection_in_Bondix and cross-referenced in the release notes at https://wiki.bondix.dev/wiki/Downloads#Release_Notes (exact patched version not enumerated in the provided intelligence - confirm with the vendor changelog before deployment). Until the upgrade is applied, restrict configuration-write privileges to the smallest possible set of trusted administrators, place the management interface behind a VPN or management-only network segment so only vetted operators can reach it, enable multi-factor authentication on administrative accounts, and audit existing environment and tunnel configuration values for suspicious shell metacharacters; these controls reduce exposure but do not eliminate the underlying injection, and tightening admin access may slow legitimate operational workflows.
