CVE-2024-49056 identifies a high-severity vulnerability in Microsoft Airlift. This vulnerability allows an authentication bypass due to assumed-immutable data, enabling authorized attackers to elevate privileges over a network. With a CVSS score of 7.3, it poses substantial risk to organizations relying on this component, warranting immediate attention.
The vulnerability is classified as a privilege escalation issue, which means that an attacker can gain elevated access to resources that should typically be protected from unauthorized users. The urgency for remediation is high, as it affects the integrity and confidentiality of data handled by the affected system.
Currently, there are no known exploits or public proofs of concept available for this vulnerability, but the exploitability is rated as high due to the nature of the flaw. Organizations should prioritize addressing this vulnerability in their patch cycles to prevent potential exploitation.
The published date of this vulnerability was November 12, 2024, and it continues to be analyzed for further insights. Organizations using Microsoft Airlift must act swiftly to mitigate risks associated with this vulnerability.
Vulnerability Details
CVE-2024-49056 enables an attacker to bypass authentication on airlift.microsoft.com by exploiting assumed-immutable data. The vulnerability is classified under CWE-302, which relates to improper restriction of operations within the privileges assigned to a user.
The CVSS vector for this vulnerability is CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N, indicating it has a network attack vector, low complexity, and requires low privileges with user interaction. The confidentiality and integrity impacts are both high, while the availability impact is none.
Technical Analysis
The root cause of CVE-2024-49056 lies in the handling of authentication data, which is improperly assumed to be immutable, thus allowing an attacker to exploit this assumption and gain elevated privileges. The attack vector is network-based, meaning that an attacker could exploit this vulnerability remotely.
The attack complexity is rated as low, as it requires minimal effort to exploit. Privileges required for exploitation are low, indicating that an authenticated user could perform this action. User interaction is required for the exploitation to succeed, which adds a layer of complexity.
The impact of a successful attack would be significant, with high confidentiality and integrity impacts but no impact on availability. Organizations must be vigilant in monitoring for potential abuse of this vulnerability.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to sensitive data and resources, which could lead to further exploitation or data breaches. The blast radius for this vulnerability is considerable, as it allows attackers to escalate privileges across the network.
Due to the high CVSS score of 7.3, organizations must assess their risk posture and prioritize patching this vulnerability immediately. The absence of known public exploits does not diminish the urgency of addressing this issue.
Organizations should ensure that they have robust security measures in place to detect and prevent attempts to exploit this vulnerability, including monitoring user activity and implementing least privilege access controls.
