[R4] SecurityCenter 5.4.4 Fixes File Upload unserialize() Function PHP Object Handling Remote File Deletion

Medium
← View More Security Advisories

Synopsis

SecurityCenter was found to use the PHP unserialize() function in several places in such a way that may allow a remote authenticated attacker to upload a crafted PHP object that resulted in the deletion of arbitrary files.

Please note that Tenable strongly recommends that SecurityCenter be installed on a subnet that is not Internet addressable.

Solution

Tenable has released SecurityCenter 5.4.4 to address these issues. The new version can be obtained from the Tenable Support Portal (https://support.tenable.com/support-center/index.php?x=&mod_id=160).

Additionally, patches have been created to address these issues for Security Center 5.4.0 through 5.4.3. The patches and associated checksums can be found at http://static.tenable.com/prod_docs/upgrade_security_center.html.

Tenable has released version 4.5.0 of the Appliance that resolves this issue. Users are strongly encouraged to use the online updating functionality or download the new version to upgrade.
