Is Centrify's DZDO command impacted by CVE-2017-1000367 (sudo privilege escalation)?

11 April,19 at 11:50 AM


Centrify Suite 2017 (5.3.0) 


Direct Authorize DZDO command on Linux only




Is Centrify's DZDO command impacted by CVE-2017-1000367 (sudo privilege escalation)?

A flaw was found in the way sudo versions 1.8.17p1 through 1.8.20p1 parse tty information from the process status file in the proc filesystem. A local user with privileges to execute commands via sudo could use this flaw to escalate their privileges to root. 

This exposure is on Linux OS's only, the sudo permissions must be granted first so this vulnerability is NOT exposed to just anybody.

A close inspection of the Centrify code has allowed us to determine that the Direct Authorize command "DZDO” which replaces sudo does not match the criteria required to be susceptible to this exploit therefore it is not impacted by this CVE.
