CVE-2024-49056
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAuthentication bypass by assumed-immutable data on airlift.microsoft.com allows an authorized attacker to elevate privileges over a network.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe vulnerability involves an authentication bypass on airlift.microsoft.com where certain data (such as tokens, cookies, or parameters) is incorrectly assumed to be immutable by the application. An authorized attacker can modify this assumed-immutable data to escalate privileges and gain unauthorized access to higher-privileged functionality or accounts.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if your environment interfaces with airlift.microsoft.comReview your application integrations, network logs, proxy configurations, and documented API endpoints for any connection to airlift.microsoft.comAffected if Your system makes requests to or integrates with airlift.microsoft.com for authentication, token handling, or privilege management
-
Inspect authentication tokens or session data sent to Microsoft servicesCapture and examine HTTP traffic or API calls destined for Microsoft endpoints; review any cookies, bearer tokens, or custom headers your application sendsAffected if Your application transmits authentication-related data (tokens, cookies, claims) to Microsoft services without cryptographic integrity verification
-
Check for privilege escalation in Microsoft service accessTest whether your current user role or permission level can be modified by altering authentication-related parameters in requests to Microsoft servicesAffected if Modifying assumed-immutable authentication data (role claims, group memberships, permission parameters) allows access to higher-privileged functionality
Your environment is affected if your systems or applications interact with airlift.microsoft.com and you rely on data that could be modified without integrity checks for authorization decisions.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement proper validation and integrity checks on all authentication-related data that should be immutable, use cryptographic protections (signed tokens, HMAC) for session state, and ensure authorization checks are performed after authentication on all sensitive operations.
