CVE-2024-39804
CVE-2024-39804 is a library injection vulnerability in Microsoft PowerPoint 16.83 for macOS that can lead to a permission bypass. A malicious actor can exploit this vulnerability by injecting a specially crafted library that takes advantage of PowerPoint's elevated privileges. This malicious code can then execute with the same permissions as PowerPoint. The relatively low SOCRadar Vulnerability Risk Score (SVRS) of 30 suggests it's not currently considered a critical immediate threat, although any "In The Wild" vulnerability needs to be monitored carefully. The impact of a successful exploit is that an attacker can effectively run arbitrary code with the same permissions as the vulnerable application. While the CVSS score is 0, the library injection technique is often used to gain control of a system, underscoring the need for prompt patching when updates become available. This vulnerability highlights the importance of secure coding practices and careful handling of external libraries within applications.
Description
CVE-2024-39804 is a library injection vulnerability found in Microsoft PowerPoint 16.83 for macOS. This vulnerability allows attackers to inject malicious libraries into PowerPoint, potentially leading to permission bypass and unauthorized access to the user's system. While the CVSS score is 7.1, indicating a high severity, SOCRadar's SVRS score of 42 suggests a lower immediate risk.
Key Insights
- Exploitation through Malicious Libraries: Attackers can craft malicious libraries that leverage PowerPoint's access privileges to gain unauthorized control over the user's system. This can include executing malicious code, stealing sensitive data, or even taking full control of the compromised system.
- Permission Bypass: This vulnerability enables attackers to bypass the standard security measures and access resources that are typically restricted. This makes the system vulnerable to various types of attacks.
- No Public Exploits or Active Exploits in the Wild: Although the vulnerability is known, there is no evidence of publicly available exploits or widespread exploitation in the wild.
- CISA's Warning: The Cybersecurity and Infrastructure Security Agency (CISA) has not yet issued a specific warning regarding this CVE. However, they routinely advise users to update software and apply security patches promptly.
Mitigation Strategies
- Software Updates: Install the latest version of Microsoft PowerPoint for macOS as soon as possible. Microsoft typically releases security patches to address vulnerabilities, and updating software is a crucial step in mitigating risks.
- Restrict User Permissions: Limit the permissions of the user account used to access PowerPoint. This can prevent malicious code from executing if injected by a compromised library.
- Antivirus Protection: Ensure that the user's system is protected by a reputable antivirus software. Antivirus solutions can detect and remove malicious libraries that might be used to exploit this vulnerability.
- Security Awareness Training: Train users on the importance of only downloading and opening files from trusted sources. This can help prevent them from accidentally downloading malicious libraries that might exploit this vulnerability.
