Microsoft a corrigé une faille critique CVE-2025-55241 dans Entra ID (score CVSS 10.0). Cette vulnérabilité permettait l'usurpation d'identité d'administrateurs globaux. #Cybersécurité #Microsoft #EntraID #Vulnerability https://lynxintel.io/microsoft-corrige-une-faille-critique-dans-entra-id/
"As businesses around the world have shifted their digital infrastructure over the last decade from self-hosted servers to the cloud, they’ve benefitted from the standardized, built-in security features of major cloud providers like Microsoft. But with so much riding on these systems, there can be potentially disastrous consequences at a massive scale if something goes wrong. Case in point: Security researcher Dirk-jan Mollema recently stumbled upon a pair of vulnerabilities in Microsoft Azure’s identity and access management platform that could have been exploited for a potentially cataclysmic takeover of all Azure customer accounts.
Known as Entra ID, the system stores each Azure cloud customer’s user identities, sign-in access controls, applications, and subscription management tools. Mollema has studied Entra ID security in depth and published multiple studies about weaknesses in the system, which was formerly known as Azure Active Directory. But while preparing to present at the Black Hat security conference in Las Vegas in July, Mollema discovered two vulnerabilities that he realized could be used to gain global administrator privileges—essentially god mode—and compromise every Entra ID directory, or what is known as a “tenant.” Mollema says that this would have exposed nearly every Entra ID tenant in the world other than, perhaps, government cloud infrastructure.
“I was just staring at my screen. I was like, ‘No, this shouldn’t really happen,’” says Mollema, who runs the Dutch cybersecurity company Outsider Security and specializes in cloud security. “It was quite bad. As bad as it gets, I would say.”"
Holy moly. As someone who spends way too much time locking down Entra ID this terrifies me. Complete unlogged access to any tenant’s global admin. Why am I even trying? Thankfully it’s fixed but where there’s smoke there’s fire. What else is lurking in that API?

It’ll never happen but Microsoft’s ethical response here is to analyze whether any tenants have been compromised by this and to disclose to the tenant owners.
It's been a packed 24 hours in the cyber world! We've got major arrests, critical vulnerabilities, nation-state activity, and a deep dive into AI's evolving role in both defence and attack. Let's get into it:
