Arbitrary File Write Vulnerability in Samsung MagicINFO 9 Server

CVE-2024-7399

What is CVE-2024-7399?

CVE-2024-7399 is a serious security vulnerability found in the Samsung MagicINFO 9 Server. This software is widely used for digital signage management, enabling organizations to control and display content across various screens. The vulnerability stems from improper restrictions on file paths, allowing attackers with sufficient skill to write arbitrary files with system-level privileges. If successfully exploited, this could lead to significant disruptions in an organization’s operations, potential data loss, and unauthorized access to sensitive information.

Technical Details

The flaw in CVE-2024-7399 arises from a failure to properly validate the pathname associated with file storage within versions of the Samsung MagicINFO 9 Server prior to version 21.1050. This inadequacy permits attackers to overwrite or create files in arbitrary locations on the server, which can have extensive ramifications, especially if sensitive files or configurations are targeted. Attackers may leverage this vulnerability to execute additional malicious actions, resembling behaviors seen in more severe attack scenarios.

Potential impact of CVE-2024-7399

1. Data Compromise: The ability to write arbitrary files could facilitate unauthorized access to sensitive data stored on the server, risking exposure of confidential organizational information.

2. Service Disruption: Malicious actors could replace or corrupt crucial files, leading to disruptions in services that rely on the MagicINFO 9 Server. This could hinder the organization’s ability to effectively communicate or engage with its audience.

3. Escalation of Attacks: By gaining system-level access, attackers could pivot to exploit further vulnerabilities within the organization’s network, increasing the potential for comprehensive breaches or ransomware deployment.
