CVE-2018-0824 is a high-severity remote code execution vulnerability that exists in "Microsoft COM for Windows". This vulnerability arises when the system fails to properly handle serialized objects. Affected operating systems include Windows 7, Windows Server 2012 R2, Windows RT 8.1, Windows Server 2008, Windows Server 2012, Windows 8.1, Windows Server 2016, Windows Server 2008 R2, Windows 10, and Windows 10 Servers.
With a CVSS score of 8.8, this vulnerability presents a substantial risk to organizations, particularly due to its potential for remote code execution. Attackers may leverage this vulnerability to execute arbitrary code on vulnerable systems, leading to unauthorized access and data exfiltration. Organizations should prioritize patching immediately to reduce exposure to this risk.
The vulnerability is currently included in the Known Exploited Vulnerabilities (KEV) catalog, which indicates its active exploitation in the wild. Organizations must take this into consideration when assessing their security posture and remediation strategies.
Given the severity of CVE-2018-0824, organizations are strongly encouraged to assess their systems for vulnerabilities and apply relevant patches as soon as possible to mitigate potential threats.
Vulnerability Details
The official description of this vulnerability states: "A remote code execution vulnerability exists in 'Microsoft COM for Windows' when it fails to properly handle serialized objects, aka 'Microsoft COM for Windows Remote Code Execution Vulnerability.'" It has been classified under CWE-502.
The vulnerability has been assigned a CVSS score of 8.8, indicating high severity. The primary attack vector is network-based, requiring low complexity and no privileges, but necessitating user interaction. The impacts on confidentiality, integrity, and availability are all rated as high.
This vulnerability affects multiple versions of Windows, including Windows 7, Windows 8.1, Windows 10, and various Windows Server versions. It was published on May 9, 2018.
Technical Analysis
The root cause of CVE-2018-0824 is the improper handling of serialized objects in Microsoft COM for Windows. This vulnerability can be exploited via specially crafted files or scripts that take advantage of the deserialization process. The attack vector is primarily network-based, which means that attackers can exploit this vulnerability remotely.
The exploitation complexity is low, requiring no privileges to execute the attack. However, user interaction is required, as the user must open a malicious file or run a script that leverages the vulnerability. The impacts of a successful exploit are severe, affecting confidentiality, integrity, and system availability.
Risk & Impact Analysis
Risk to organizations includes potential remote code execution, leading to unauthorized system access, data breaches, and compromised integrity of systems and data. Given the critical nature of this vulnerability and its inclusion in the KEV catalog, it is imperative for organizations to take immediate action to mitigate potential risks.
Organizations should assess their systems for any instances of the affected products and prioritize patching in their security management processes. The urgency is high due to the potential for widespread exploitation and the serious consequences of successful attacks.
