A critical zero-click remote code execution (RCE) vulnerability has been discovered in Microsoft Outlook.
This vulnerability, designated as CVE-2024-30103, enables attackers to run arbitrary code by sending a specially designed email. When the recipient opens the email, the exploit is triggered.
The vulnerability, CVE-2024-30103, is particularly alarming due to its zero-click nature. Unlike traditional phishing attacks that require user interaction, this flaw can be exploited without any action from the user.
Opening the malicious email alone is enough to compromise the system, making it a powerful weapon for cybercriminals and greatly reducing the barriers to successful exploitation.

According to Morphisec’s detailed analysis, the vulnerability lies in the way Microsoft Outlook processes certain email components.
When a specially crafted email is opened, it triggers a buffer overflow, allowing the attacker to execute arbitrary code with the same privileges as the user running Outlook. This can lead to a full system compromise, data theft, or further propagation of malware within a network.
Impact and Mitigation
Given the widespread use of Microsoft Outlook in corporate and personal environments, CVE-2024-30103’s potential impact is vast. Organizations are particularly at risk, as a successful exploit could lead to significant data breaches, financial loss, and reputational damage.
Microsoft has acknowledged the vulnerability and released a security patch to address the issue. Users and administrators are strongly advised to apply the latest updates to mitigate the risk. Additionally, robust email filtering and monitoring solutions can help detect and block malicious emails before they reach end-users.
Cybersecurity experts have emphasized the critical nature of this vulnerability. “Zero-click vulnerabilities are particularly dangerous because they require no user interaction, making them highly effective for attackers,” said a spokesperson from Morphisec. “Organizations must prioritize patching and adopt a multi-layered security approach to protect against such sophisticated threats.”
As of the latest updates, no known attacks are in the wild exploiting the Microsoft Outlook vulnerability CVE-2024-30103.
