Description
One Identity Password Manager before 5.13.1 allows Kiosk Escape. This product enables users to reset their Active Directory passwords on the login screen of a Windows client. It launches a Chromium based browser in Kiosk mode to provide the reset functionality. The escape sequence is: go to the Google ReCAPTCHA section, click on the Privacy link, observe that there is a new browser window, navigate to any website that offers file upload, navigate to cmd.exe from the file explorer window, and launch cmd.exe as NT AUTHORITY\SYSTEM.
Comprehensive Technical Analysis of CVE-2023-48654
1. Vulnerability Assessment and Severity Evaluation
CVE ID: CVE-2023-48654 CVSS Score: 9.8
The vulnerability in One Identity Password Manager before version 5.13.1 allows for a Kiosk Escape, which can lead to privilege escalation. The CVSS score of 9.8 indicates a critical severity level, reflecting the potential for significant impact on affected systems. This high score is due to the ease of exploitation and the severe consequences of successful exploitation, including full system compromise.
2. Potential Attack Vectors and Exploitation Methods
The primary attack vector involves exploiting the Kiosk mode of the Chromium-based browser used by One Identity Password Manager. The steps to exploit this vulnerability are as follows:
- Access the Google ReCAPTCHA Section: Navigate to the Google ReCAPTCHA section within the Kiosk mode.
- Click on the Privacy Link: Click on the Privacy link within the ReCAPTCHA section.
- Open a New Browser Window: Observe that a new browser window opens, which is not restricted by Kiosk mode.
- Navigate to a File Upload Website: Use the new browser window to navigate to any website that offers file upload functionality.
- Launch cmd.exe: From the file explorer window, navigate to and launch
cmd.exe. - Execute Commands as NT AUTHORITY\SYSTEM: Execute commands with elevated privileges, effectively gaining full control over the system.
This sequence allows an attacker to escape the Kiosk mode and gain system-level access, leading to potential data exfiltration, system manipulation, and further lateral movement within the network.
3. Affected Systems and Software Versions
Affected Software: One Identity Password Manager Affected Versions: All versions before 5.13.1
Systems running One Identity Password Manager versions prior to 5.13.1 are vulnerable to this Kiosk Escape and privilege escalation issue. Organizations using this software for password management and reset functionalities are at risk.
4. Recommended Mitigation Strategies
- Update Software: Immediately update One Identity Password Manager to version 5.13.1 or later, which includes the patch for this vulnerability.
- Restrict Kiosk Mode: Implement additional restrictions on Kiosk mode to prevent unauthorized access to system resources.
- Monitor and Log Activities: Enhance monitoring and logging of activities within the Kiosk mode to detect any suspicious behavior.
- Network Segmentation: Segment the network to limit the potential impact of a compromised system.
- User Education: Educate users about the risks associated with Kiosk mode and the importance of reporting any unusual activities.
5. Impact on Cybersecurity Landscape
The discovery of this vulnerability highlights the importance of securing Kiosk mode implementations, especially in environments where sensitive operations like password resets are performed. It underscores the need for robust security measures in software that interacts with critical systems like Active Directory. The high CVSS score indicates the potential for widespread impact if exploited, making it a significant concern for organizations relying on One Identity Password Manager.
6. Technical Details for Security Professionals
Exploitation Details:
- The vulnerability leverages the lack of proper restrictions in the Kiosk mode of the Chromium-based browser.
- The escape sequence involves navigating to external links within the ReCAPTCHA section, which opens a new browser window without Kiosk mode restrictions.
- The new browser window can be used to access system resources, including launching
cmd.exewith elevated privileges.
Detection and Response:
- Implement intrusion detection systems (IDS) to monitor for unusual activities within Kiosk mode.
- Regularly review logs for any unauthorized access attempts or suspicious activities.
- Conduct regular security audits and vulnerability assessments to identify and mitigate similar issues.
Patch Analysis:
- The patch in version 5.13.1 addresses the Kiosk mode escape by enforcing stricter controls on browser navigation and preventing the opening of new browser windows with unrestricted access.
In conclusion, CVE-2023-48654 represents a critical vulnerability that requires immediate attention from organizations using One Identity Password Manager. By understanding the technical details and implementing the recommended mitigation strategies, security professionals can effectively protect their systems from potential exploitation.
