The vulnerabilities had been located in Azure Bastion and Azure Container Registry – two frequently made use of solutions in the Azure ecosystem.
“Despite many Azure security enhancements to mitigate the postMessage iframe XSS vulnerability, we continue to managed to uncover two Azure services – Azure Bastion and Azure Container Registry – that had been exploitable through this vulnerability,” Orca wrote in a report printed these days.
The very first of these lies in the mishandling of the postMessage handler, which authorized attackers to exploit three distinct postMessage conditions.
By sending a specially crafted postMessage, attackers could execute destructive scripts, most likely compromising person sessions and delicate facts.
Meanwhile, the Azure Container Registry flaw allowed attackers to inject and execute arbitrary scripts in just the context of the container registry.
This enabled them to manipulate the habits of the influenced web software and most likely steal delicate facts or perform unauthorized steps.
“The vulnerabilities authorized unauthorized obtain to the victim’s session inside the compromised Azure services iframe, which can guide to serious implications, including unauthorized facts obtain, unauthorized modifications, and disruption of the Azure providers iframes,” Orca wrote.

The organization promptly reported the vulnerabilities to Microsoft: “Upon discovery of these vulnerabilities, we immediately informed the Microsoft Security Response Center (MSRC), who were being capable to reproduce the issues.”
“Both vulnerabilities have now been mounted and confirmed – with no further motion essential by Azure users,” reads the report.
Its publication arrives a few months right after Orca Security disclosed details about a independent flaw in Microsoft’s Azure Service Material Explorer (SFX) they named “Super FabriXss.”
