CVE-2024-49105 is a high-severity vulnerability affecting Microsoft Remote Desktop Client, potentially allowing remote code execution. This vulnerability is classified as high due to its CVSS score of 8.4, which indicates significant risk to organizations. The vulnerability stems from issues in the handling of requests, where specific conditions may allow attackers to execute arbitrary code remotely.
The risk to organizations includes unauthorized access to sensitive systems, data loss, and potential service disruptions. Attackers may leverage this vulnerability to gain control over affected systems, posing a serious threat to business operations. Given its high severity, organizations should prioritize patching immediately.
As of now, there is no public exploit confirmed for this vulnerability, but its potential for exploitation remains a concern. Organizations must remain vigilant and monitor their systems closely to prevent any attempts of exploitation.
With the vulnerability disclosed on December 12, 2024, it is crucial for organizations to take immediate action to address this issue and safeguard their environments.
Vulnerability Details
The official description states that this vulnerability allows remote code execution in Microsoft Remote Desktop Client. The vulnerability is classified under CWE-284, which refers to improper access control. The CVSS 3.1 score of 8.4 indicates that this vulnerability has a low attack complexity but requires high privileges and user interaction for exploitation.
Affected products include the Remote Desktop Client, Windows 10 versions 1507, 1607, 1809, 21H2, and 22H2, as well as Windows 11 versions 22H2, 23H2, and 24H2. The vulnerability also affects various Windows Server versions.
This vulnerability was published on December 12, 2024, and organizations should ensure they update to the latest versions to mitigate the risks associated with it.
Technical Analysis
The root cause of CVE-2024-49105 lies in the handling of network requests by the Remote Desktop Client. The attack vector is through the network, which allows remote attackers to send specially crafted requests to the affected system. The attack complexity is low, meaning that exploitation does not require advanced skills.
The privileges required for exploitation are high, which means that an attacker must have valid credentials to affect the system. User interaction is required during the attack, as the user must initiate the connection to the malicious server or execute a malicious payload.
The impacts on confidentiality, integrity, and availability are all rated as high, indicating that successful exploitation could lead to complete system compromise, data theft, and service outages.
Risk & Impact Analysis
Real-world deployment risk from this vulnerability is significant, given the wide usage of Remote Desktop Client in enterprise environments. Organizations need to consider the potential blast radius of an exploit, which could affect multiple systems if attackers gain access to administrative credentials.
As this vulnerability has a CVSS score of 8.4, organizations should address it in their priority patch cycle. The urgency is further emphasized by the potential for attackers to exploit this vulnerability if it becomes publicly available, despite the current lack of confirmed exploits.
Monitoring systems for unusual activity and ensuring that all user access is tightly controlled will help mitigate the risk associated with this vulnerability.
