This vulnerability allows an attacker to spoof elements within Microsoft Teams for iOS, potentially misleading users and affecting the integrity of communications. With a CVSS score of 6.5, this medium-severity vulnerability poses a risk to organizations utilizing the application. The attack vector is network-based, indicating that exploitation can occur remotely without physical access to the target device.
Risk to organizations includes unauthorized access to sensitive information and disruption of communication channels. Although there is currently no known exploit available, organizations should remain vigilant as the absence of an exploit does not eliminate the risk associated with this vulnerability. Organizations should prioritize patching immediately to mitigate potential impacts.
The vulnerability was published on August 13, 2024, and affects all versions of Microsoft Teams for iOS prior to 6.19.2. Organizations using affected versions should take immediate action to remediate this vulnerability, ensuring that they implement necessary updates to protect against potential spoofing attacks.
Given the nature of this vulnerability, it is essential for organizations to stay informed about the latest security updates from Microsoft and to apply patches as soon as they become available.
Vulnerability Details
The CVE-2024-38197 vulnerability is classified as a spoofing vulnerability specific to Microsoft Teams for iOS. The official CVE description states: 'Microsoft Teams for iOS Spoofing Vulnerability'. The vulnerability is assigned a CVSS score of 6.5, indicating a medium severity level.
The vulnerability has a CWE classification of CWE-451, which refers to 'User Interface Misrepresentation'. This indicates that the vulnerability stems from a flaw in the way the user interface is presented, potentially allowing attackers to create misleading representations.
The affected product is Microsoft Teams, specifically versions prior to 6.19.2 on iOS. The vulnerability was reported on August 13, 2024, and is classified under CVSS version 3.1.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of user interface elements within Microsoft Teams for iOS. This allows an attacker to manipulate the appearance of elements, leading to potential spoofing. The attack vector is network-based, meaning that an attacker does not need physical access to the device to exploit this vulnerability.
The attack complexity is considered low, as no special conditions or privileges are required to execute an attack. User interaction is not necessary, allowing attackers to carry out the exploitation without user consent.
The confidentiality impact is low, as the vulnerability primarily affects the integrity of communications rather than the confidentiality of data. Similarly, the integrity impact is also low, as the attack does not lead to unauthorized data modification, but rather misrepresentation.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2024-38197 is significant for organizations that rely on Microsoft Teams for communication and collaboration. The potential for spoofing can undermine trust in the application and lead to the dissemination of misinformation. Given the network attack vector and low attack complexity, organizations should assess their exposure and the potential blast radius of an attack.
Organizations should address this vulnerability in their priority patch cycle to protect against potential exploitation. The CVSS score indicates a medium urgency for remediation, with a recommendation to schedule patching as soon as possible.
