CVE-2023-28501 Explained : Impact and Mitigation

This article provides detailed information on CVE-2023-28501, including its description, impact, technical details, and mitigation strategies.

Understanding CVE-2023-28501

CVE-2023-28501 refers to a heap-based buffer overflow vulnerability found in Rocket Software's UniData and UniVerse products. This vulnerability, if exploited successfully, can result in remote code execution with root user privileges.

What is CVE-2023-28501?

Rocket Software's UniData versions before 8.2.4 build 3003 and UniVerse versions before 11.3.5 build 1001 or 12.2.1 build 2002 are affected by a heap-based buffer overflow in the unirpcd daemon. This vulnerability poses a significant risk as it can potentially allow attackers to execute malicious code remotely as the root user.

The Impact of CVE-2023-28501

The impact of CVE-2023-28501 is severe, as it could lead to unauthorized remote code execution on vulnerable systems. Attackers exploiting this vulnerability could gain complete control over the affected systems, compromising data integrity and confidentiality.

Technical Details of CVE-2023-28501

The following technical aspects are crucial to understanding the CVE-2023-28501 vulnerability:

Vulnerability Description

The vulnerability stems from a heap-based buffer overflow in the unirpcd daemon of Rocket Software's UniData and UniVerse products. By sending specially crafted requests to the affected services, attackers can trigger this buffer overflow, potentially leading to remote code execution.

Affected Systems and Versions

Rocket Software UniData versions prior to 8.2.4 build 3003 and UniVerse versions before 11.3.5 build 1001 or 12.2.1 build 2002 are impacted by this vulnerability. Users of these versions should take immediate action to mitigate the risk.

Exploitation Mechanism

Exploiting CVE-2023-28501 involves sending malicious inputs that exceed the allocated buffer size within the unirpcd daemon. By carefully crafting these inputs, attackers can overwrite adjacent memory locations and execute arbitrary code on vulnerable systems.

Mitigation and Prevention

To address CVE-2023-28501 and enhance system security, consider the following mitigation strategies:

Immediate Steps to Take

Update Rocket Software UniData to version 8.2.4 build 3003 or later.
Update Rocket Software UniVerse to version 11.3.5 build 1001 or 12.2.1 build 2002 or newer.
Monitor and restrict network access to the affected services to minimize exposure to potential attacks.

Long-Term Security Practices

Implement robust network security measures to prevent unauthorized access.
Conduct regular security assessments and vulnerability scans to identify and address potential weaknesses.
Educate users and IT staff on best practices for safe computing and data security.

Patching and Updates

Ensure timely installation of security patches and updates provided by Rocket Software to address known vulnerabilities and enhance system resilience against potential threats. Regularly review security advisories and apply patches promptly to maintain a secure environment.
