CVE-2026-47359: CWE-78 Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in Apache Software Foundation Apache CloudStack
CVE-2026-47359 is an OS command injection vulnerability in Apache CloudStack's NAS backup provider plugin. It affects the addBackupRepository and updateBackupRepository APIs, which accept unsanitized command options. A malicious operator can inject arbitrary commands that execute on the KVM hypervisor host during backup restore operations. The vulnerability affects Apache CloudStack versions from 4.20.0.0 through 4.20.3.0 and 4.21.0.0 through 4.22.1.0. Fixed versions are 4.20.3.1 and 4.22.1.1 or later.
AI Analysis
Technical Summary
This vulnerability involves improper neutralization of special elements in OS commands (CWE-78) within Apache CloudStack's NAS backup provider plugin. Specifically, the addBackupRepository API (since version 4.20.0.0) and updateBackupRepository API (since 4.22.0.0) accept command options without proper sanitization. A malicious operator account can exploit this flaw to inject arbitrary OS commands that execute on the KVM hypervisor host when any account performs a backup restore. The affected versions include 4.20.0.0 through 4.20.3.0 and 4.21.0.0 through 4.22.1.0. The issue is resolved in versions 4.20.3.1 and 4.22.1.1 or later.
Potential Impact
Successful exploitation allows a malicious operator to execute arbitrary OS commands on the KVM hypervisor host during backup restore operations. This can lead to unauthorized command execution with potentially high privileges on the host system, compromising the integrity and security of the hypervisor environment.
Mitigation Recommendations
Users should upgrade Apache CloudStack to versions 4.20.3.1 or 4.22.1.1 or later, where this vulnerability has been fixed. No other mitigation or temporary workaround is indicated in the provided data. Patch status is confirmed by the vendor advisory information embedded in the description.
