CVE-2025-24241

Comprehensive Technical Analysis of CVE-2025-24241

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-24241 CVSS Score: 9.8

The CVSS score of 9.8 indicates a critical vulnerability. This high score is likely due to the potential for significant impact on confidentiality, integrity, and availability. The vulnerability involves a configuration issue that allows an app to trick users into copying sensitive data to the pasteboard, which can then be accessed by malicious actors.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Phishing Attacks: Malicious apps could be disguised as legitimate applications, tricking users into installing them.
• Social Engineering: Attackers could exploit user trust by mimicking trusted applications or services.
• Malicious Websites: Users could be directed to websites that prompt them to copy sensitive data, which is then captured by the malicious app.

Exploitation Methods:

• Clipboard Hijacking: The malicious app could monitor the pasteboard for sensitive data such as passwords, credit card numbers, or personal information.
• Data Exfiltration: Once the data is copied to the pasteboard, the malicious app can exfiltrate it to a remote server controlled by the attacker.

3. Affected Systems and Software Versions

Affected Systems:

• macOS Ventura versions prior to 13.7.5
• macOS Sequoia versions prior to 15.4
• macOS Sonoma versions prior to 14.7.5

Software Versions:

• Any application that interacts with the pasteboard on the affected macOS versions.

4. Recommended Mitigation Strategies

Immediate Actions:

• Update Systems: Ensure all affected macOS systems are updated to the latest versions (Ventura 13.7.5, Sequoia 15.4, Sonoma 14.7.5).
• User Education: Educate users about the risks of copying sensitive data and the importance of verifying the legitimacy of applications.

Long-Term Strategies:

• Enhanced Security Policies: Implement stricter policies for application installation and usage.
• Regular Audits: Conduct regular security audits to identify and mitigate configuration issues.
• Monitoring Tools: Use monitoring tools to detect and alert on suspicious pasteboard activities.

5. Impact on Cybersecurity Landscape
