CVE-2026-78424: CWE-78 Improper neutralization of special elements used in an OS command ('OS command injection') in SUSE NeuVector
Improper parameter handling in NeuVector allows any authenticated user who holds the namespaced Runtime Policies (write) permission or anyone with access to NeuVector’s internal gRPC certificate key pair the ability to inject OS commands in the privileged enforcer container, which can lead to the complete compromise of the worker node. This affects NeuVector 5.4 before 5.4.11, NeuVector 5.5 before 5.5.4, NeuVector 5.6 before 5.6.2 and potentially older versions.
AI Analysis
Technical Summary
This vulnerability arises from improper neutralization of special elements used in OS commands (CWE-78) within NeuVector. Authenticated users holding the namespaced Runtime Policies (write) permission or those with access to NeuVector's internal gRPC certificate key pair can inject OS commands into the privileged enforcer container. Successful exploitation can lead to full compromise of the worker node. Affected versions include NeuVector 5.4 before 5.4.11, 5.5 before 5.5.4, and 5.6 before 5.6.2, as well as potentially older versions.
Potential Impact
Exploitation can result in complete compromise of the worker node, impacting confidentiality, integrity, and availability. The CVSS 3.1 score is 8.8 (high severity), reflecting network attack vector, low attack complexity, required privileges, no user interaction, and high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
The vulnerability is fixed in NeuVector versions 5.4.11, 5.5.4, and 5.6.2. Users should upgrade to these or later versions to remediate the issue. No vendor advisory content was provided to indicate alternative mitigations or temporary fixes.
