CVE-2026-19682: CWE-78 Improper neutralization of special elements used in an OS command ('OS command injection') in Tenable, Inc. Security Center
A command injection vulnerability exists in Security Center where a remote, unauthenticated attacker could exploit this issue to execute arbitrary commands on the underlying operating system with the privileges of the service account.
AI Analysis
Technical Summary
This vulnerability (CWE-78) in Tenable Security Center enables remote unauthenticated attackers to perform OS command injection, executing arbitrary commands on the underlying system with service account privileges. The CVSS 3.1 vector AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H reflects that the attack requires low complexity, no user interaction, and results in complete system compromise. No vendor advisory or patch information is currently provided.
Potential Impact
Successful exploitation allows an attacker to execute arbitrary OS commands remotely without authentication, potentially leading to full system compromise including confidentiality, integrity, and availability impacts. The attacker gains the same privileges as the Security Center service account, which could be significant depending on the deployment environment.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround is currently documented. Until a patch is available, restrict network access to the Security Center service and monitor for suspicious activity related to command execution attempts.
