Feiten
FortiNet heeft een kwetsbaarheid verholpen in FortiOS en FortiProxy.
Interpretaties
De kwetsbaarheid bevindt zich in de node.js implementatie van de management-webinterface en stelt een kwaadwillende in staat om authenticatie te omzeilen om zo zonder voorafgaande authenticatie of autorisaties super-admin te worden op het kwetsbare systeem.
Voor succesvol misbruik moet de kwaadwillende toegang hebben tot de management-webinterface. Het is goed gebruik een dergelijke interface niet publiek toegankelijk te hebben, maar af te steunen in een separate beheer-omgeving.
FortiNet meldt dat actief misbruik is waargenomen op FortiGate systemen waarop de kwetsbare FortiOS of FortiProxt draait. Ook hebben onderzoekers Proof-of-Concept-Code (PoC) gepubliceerd, waarmee de kwetsbaarheid kan worden aangetoond.
FortiNet heeft Indicators of Compromise (IoC's) vrijgegeven, waarmee mogelijke compromittatie kan worden ontdekt:
- Following login activity log with random scrip and dstip:
`type="event" subtype="system" level="information" vd="root" logdesc="Admin login successful" sn="1733486785" user="admin" ui="jsconsole" method="jsconsole" srcip=1.1.1.1 dstip=1.1.1.1 action="login" status="success" reason="none" profile="super_admin" msg="Administrator admin logged in successfully from jsconsole"`
- Following admin creation log with seemingly randomly generated user name and source IP:
`type="event" subtype="system" level="information" vd="root" logdesc="Object attribute configured" user="admin" ui="jsconsole(127.0.0.1)" action="Add" cfgtid=1411317760 cfgpath="system.admin" cfgobj="vOcep" cfgattr="password[*]accprofile[super_admin]vdom[root]" msg="Add system.admin vOcep"`
Oplossingen
FortiNet heeft updates en handelingsperspectieven uitgebracht om de kwetsbaarheid te verhelpen en eventuele compromittatie te onderzoeken. Tevens adviseert FortiNet expliciet om toegang tot de management-webinterface te blokkeren of zoveel als mogelijk te beperken middels 'local-in policies'.
