Attackers could exploit a now-patched spoofing vulnerability in Service Fabric Explorer to gain admin privileges and hijack Azure Service Fabric clusters.
Service Fabric is a platform for business-critical applications that hosts over 1 million apps and powers many Microsoft products, including but not limited to Microsoft Intune, Dynamics 365, Skype for Business, Cortana, Microsoft Power BI, and multiple core Azure services.
Service Fabric Explorer, an open-source tool that can be used as a hosted solution or as a desktop app, allows Azure admins to manage and inspect nodes and cloud applications in Azure Service Fabric clusters.
Orca Security found an SFX spoofing flaw dubbed FabriXss that could enable potential attackers to gain full Administrator permissions and take over Service Fabric clusters.
Microsoft says FabriXss exploits can only be used in attacks targeting older, unsupported versions of Service Fabric Explorer, with the current default SFX web client not being vulnerable to attacks.
In June, Microsoft also fixed a Service Fabric container escape bug dubbed FabricScape that allowed threat actors to escalate privileges to root and gain control of the host node, compromising the entire SF Linux cluster.
