CVE-2023-25266 Explained : Impact and Mitigation

This CVE record was published on February 28, 2023, and involves an issue discovered in Docmosis Tornado prior to version 2.9.5. The vulnerability allows an authenticated attacker to manipulate the Office directory setting to point to a remote network path, resulting in the execution of the soffice binary under the attacker's control and leading to arbitrary remote code execution (RCE).

Understanding CVE-2023-25266

This section delves into the details of CVE-2023-25266, explaining the vulnerability and its impact.

What is CVE-2023-25266?

CVE-2023-25266 is a security flaw in Docmosis Tornado that enables an authenticated attacker to modify the Office directory setting to reference an external network path. By exploiting this vulnerability, the attacker gains the ability to execute the soffice binary on the host system, thereby achieving arbitrary remote code execution.

The Impact of CVE-2023-25266

The impact of CVE-2023-25266 is significant as it allows an attacker to gain unauthorized access to systems running vulnerable versions of Docmosis Tornado and execute arbitrary code remotely. This exploit could lead to severe consequences such as data breaches, system compromise, and unauthorized access to sensitive information.

Technical Details of CVE-2023-25266

In this section, we will explore the technical aspects of CVE-2023-25266, including the vulnerability description, affected systems, and the exploitation mechanism.

Vulnerability Description

The vulnerability in Docmosis Tornado prior to version 2.9.5 arises from a flaw that enables authenticated attackers to manipulate the Office directory setting, leading to the execution of the soffice binary under their control. This unauthorized execution can result in the execution of arbitrary remote code on the target system.

Affected Systems and Versions

The vulnerability impacts Docmosis Tornado versions before 2.9.5. Systems running these vulnerable versions are at risk of exploitation by authenticated attackers aiming to execute malicious code remotely.

Exploitation Mechanism

To exploit CVE-2023-25266, an authenticated attacker first alters the Office directory setting in Docmosis Tornado to point to a remote network path. This manipulation triggers the execution of the soffice binary under the attacker's control, enabling them to execute arbitrary remote code on the target system.

Mitigation and Prevention

Protecting systems from CVE-2023-25266 requires immediate action to mitigate the risk of exploitation and prevent unauthorized access to vulnerable systems.

Immediate Steps to Take

Update Docmosis Tornado to version 2.9.5 or later to patch the vulnerability and prevent attackers from exploiting the flaw.
Implement access controls and authentication mechanisms to restrict unauthorized access to critical system settings and directories.
Monitor network traffic and system logs for any suspicious activities that may indicate attempted exploitation of the vulnerability.

Long-Term Security Practices

Regularly update software and applications to the latest versions to ensure that known vulnerabilities are addressed promptly.
Conduct security assessments and penetration testing to identify and remediate weaknesses in the system that could be exploited by attackers.
Educate users and IT staff on best security practices, including password hygiene, access control, and incident response procedures.

Patching and Updates

Vendor-released patches and updates play a crucial role in addressing CVE-2023-25266. It is essential for organizations to apply patches promptly, especially for critical vulnerabilities like the one in Docmosis Tornado, to reduce the risk of exploitation and protect their systems from potential attacks.
