CVE-2022-0486 in Network and Deception
Summary
by MITRE • 05/18/2022
Improper file permissions in the CommandPost, Collector, Sensor, and Sandbox components of Fidelis Network and Deception enables an attacker with local, administrative access to the CLI to modify affected files and enable escalation of privileges equivalent to the root user. The vulnerability is present in Fidelis Network and Deception versions prior to 9.4.5. Patches and updates are available to address this vulnerability.

The vulnerability described in CVE-2022-0486 represents a critical privilege escalation flaw affecting Fidelis Network and Deception security platforms. This weakness stems from improper file permissions within several core components including CommandPost, Collector, Sensor, and Sandbox modules. The vulnerability specifically targets systems where local administrative access has been compromised through CLI exploitation, creating a significant attack vector for malicious actors seeking elevated system privileges. The affected versions prior to 9.4.5 demonstrate a fundamental failure in access control implementation that directly undermines the security posture of organizations relying on these platforms for network defense and deception operations.
The technical root cause of this vulnerability lies in the inadequate permission settings applied to critical system files within the Fidelis components. When an attacker gains local administrative access through the command line interface, they can leverage the flawed file permissions to modify essential system files that should normally be protected from unauthorized modification. This misconfiguration creates a path for privilege escalation that allows the attacker to achieve root-level system access equivalent to the highest administrative privileges available on the system. The vulnerability operates at the operating system level where file system permissions are not properly enforced, enabling attackers to bypass normal security boundaries that should prevent such modifications.
The operational impact of this vulnerability extends beyond simple privilege escalation to encompass potential full system compromise and data exfiltration capabilities. Organizations utilizing Fidelis Network and Deception platforms face significant risk when exposed to this vulnerability, as it essentially provides attackers with the ability to completely subvert the security controls these platforms are designed to provide. The compromise of CommandPost, Collector, Sensor, and Sandbox components creates a cascading effect where attackers can manipulate core security functions, potentially disabling or corrupting security monitoring capabilities while simultaneously gaining unrestricted access to system resources and sensitive data. This vulnerability directly violates the principle of least privilege and undermines the integrity of the entire security infrastructure.
Security mitigations for CVE-2022-0486 primarily involve applying the vendor-provided patches and updates that address the improper file permission configurations. Organizations should immediately upgrade their Fidelis Network and Deception installations to version 9.4.5 or later to remediate this vulnerability. Additionally, system administrators should conduct thorough permission audits of the affected components to ensure no unauthorized modifications have occurred. The vulnerability aligns with CWE-732, which addresses improper file permissions that allow unauthorized access to system resources, and represents a clear violation of the principle of least privilege as outlined in the MITRE ATT&CK framework. Network defenders should implement monitoring for suspicious file modification activities and establish baseline configurations for proper file permissions across all security components to prevent similar issues from occurring in the future.
