Compensating controls
- Validate the affected product branch and deploy the verified fixed release.
- Restrict local access and enforce least privilege on affected hosts.
- Monitor vendor guidance and exploitation sources for a material change.
Verification
- Confirm that the asset runs Microsoft Azure Identity Library and falls inside the recorded affected range.
- Verify the installed build against the product-specific fixed version after deployment.
- Validate exposure, authentication requirements and compensating controls in the actual environment.
- Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.

CVE-2024-35255 · CSAF 2.0 · revision 3 · finalRed Hat Product Securityazure-identity: Azure Identity Libraries Elevation of Privilege Vulnerability in github.com/Azure/azure-sdk-for-go/sdk/azidentity
The vendor explicitly identifies these products as affected by this CVE.
- aap-cloud-metrics-collector-container as a component of Red Hat Ansible Automation Platform 2
- azure-identity as a component of Red Hat build of Apache Camel for Spring Boot 3
- azure-identity as a component of Red Hat build of Quarkus

- Summary
- A flaw was found in Microsoft's Azure Identity Libraries and the Microsoft Authentication Library (MSAL). The flaw arises from a race condition—a scenario where the timing of events leads to unexpected behavior—during concurrent operations on shared resources. This can result in privilege escalation, allowing attackers to gain unauthorized access to sensitive information. The vulnerability affects multiple versions of these libraries across various programming languages, including Java, .NET, Node.js, Python, JavaScript, C++, and Go. Microsoft has addressed this issue by releasing updated versions of the affected libraries. Users are strongly advised to upgrade to these patched versions to mitigate potential security risks.
- Remediation

What, why and how
Azure Identity Libraries and Microsoft Authentication Library Elevation of Privilege Vulnerability
What
Azure Identity Libraries and Microsoft Authentication Library Elevation of Privilege Vulnerability
Why
The product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently.
How
An attacker operating through local access may attempt exploitation with low privileges. If successful, the issue may gain additional privileges.

02
Exploit reality and attack path
CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
Observed exploitation No confirmed evidence
?
Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
Public PoC / exploit material None recorded
?
Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
- Likely attack path
- local access → Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') → gain additional privileges
- Attack surface
- Local
- Privileges required
- Low: a basic authenticated account is required
- User interaction
- None
- Attack complexity
- Low: no specialised conditions are recorded
- Security boundary
- Unchanged: impact remains within the vulnerable component's security authority
- Weakness
?
CWE means Common Weakness Enumeration: a standard category for the underlying weakness. - CWE-362 ↗
CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition'). The product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently.
- CVSS vector
?
CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity. CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:CCommon Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.
AVLocalAttack vector: The attacker needs local access to the vulnerable system.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRLowPrivileges required: The attacker needs basic user-level privileges.UINoneUser interaction: No action by another user is required.SUnchangedScope: The security impact remains within the vulnerable component's authority.CHighConfidentiality impact: A successful attack can cause a major loss.INoneIntegrity impact: No direct loss is represented by this metric.ANoneAvailability impact: No direct loss is represented by this metric.- Post-exploitation / living off the land
- The issue can support a local privilege or sandbox boundary transition; normal system utilities may then be available in the gained context.
