CVE-2023-28502 : Vulnerability Insights and Analysis

This CVE-2023-28502 revolves around a stack buffer overflow vulnerability found in Rocket Software UniData and UniVerse versions, potentially leading to remote code execution as the root user. The vulnerability was published on March 29, 2023, by Rapid7.

Understanding CVE-2023-28502

This section will delve into what CVE-2023-28502 is all about, its impact, technical details, and mitigation strategies.

What is CVE-2023-28502?

Rocket Software UniData versions before 8.2.4 build 3003 and UniVerse versions before 11.3.5 build 1001 or 12.2.1 build 2002 are susceptible to a stack-based buffer overflow in the "udadmin" service. This vulnerability can potentially allow attackers to execute remote code as the root user, posing a significant security risk.

The Impact of CVE-2023-28502

The impact of this vulnerability is severe, as it enables attackers to exploit the stack buffer overflow in the affected UniData and UniVerse versions, leading to unauthorized remote code execution with elevated privileges.

Technical Details of CVE-2023-28502

Understanding the vulnerability description, affected systems and versions, as well as the exploitation mechanism is crucial to address CVE-2023-28502 effectively.

Vulnerability Description

The vulnerability arises due to a stack-based buffer overflow in the "udadmin" service of Rocket Software UniData and UniVerse versions. This flaw can be exploited by attackers to execute arbitrary code remotely.

Affected Systems and Versions

Rocket Software UniData versions prior to 8.2.4 build 3003 and UniVerse versions prior to 11.3.5 build 1001 or 12.2.1 build 2002 are impacted by this vulnerability, putting systems with these versions at risk.

Exploitation Mechanism

By taking advantage of the stack buffer overflow in the "udadmin" service, threat actors can craft malicious input to trigger the vulnerability, potentially leading to unauthorized remote code execution.

Mitigation and Prevention
