Stormshield Network Security

CVSS v2 Overall Score: 3.1      

Analysis

Impacted version

This vulnerability could allow an attacker with a local access (ability to run on SNS his own code or script) to the appliance to leak sensitive information.

This vulnerability is useless for an attacker who already have administrator access because an administrator is the highest privileges on the appliance.

As this vulnerability can only be exploited locally, it can not provide an external attacker access to an SNS appliance.

This vulnerability is mitigated when hyperthreading is disabled on the processor.

Concerning virtual appliances or administration tools like Stromshield Visibility Center or Stormshield Management Center you should ensure your hypervisor is up to date.

• SNi40

Workaround solution

Solution

Keep your appliances updated in order to limit the exploitation of other vulnerabilities that could let an attacker exploit the ZombieLoad vulnerability in order to get higher privileges.

As stated in the analysis, this attack can only be run locally on a hyperthreaded processor; SNS is not using hyperthreading and allows only one user locally, this user already has the highest priviledges. Therefore this vulnerability will not provide more priviledges than the current user. Consequently, SNS users are not put at risk and no fix needs to be applied.

Analysis

Impacted version

This vulnerability could allow an attacker with a local access to the appliance to leak sensitive information.

This vulnerability is useless for an attacker who already have administrator access because an administrator is the highest privileges on the appliance.
It means that this vulnerability is only useful for an attacker exploiting another old vulnerability on the appliance.

Consequently, it is highly recommended to keep your appliances updated.

• PSX3

Workaround solution

Solution

Keep your appliances updated in order to limit the exploitation of other vulnerabilities that could let an attacker exploit the ZombieLoad vulnerability in order to get higher privileges.

As stated in the analysis, the ZombieLoad vulnerability requires a local access to the appliance. The only user being able to run code on the appliance is the administrator who already has the highest privileges. Consequently, Fast users are not put at risk and no fix needs to be applied.
