Vulnerability Details

The vulnerability is characterized by improper limitation of a pathname to a restricted directory in Samsung MagicINFO 9 Server versions before 21.1050. This flaw allows attackers to write arbitrary files as system authority, which can lead to unauthorized access and control over affected systems. The vulnerability is classified under CWE-22 and CWE-434.

The CVSS score for this vulnerability is 8.8, categorized as high severity. The CVSS vector indicates that the attack vector is network-based, with low attack complexity and low privileges required, meaning that an attacker does not need extensive access to exploit this vulnerability effectively.

Samsung's MagicINFO 9 Server is affected, with the vulnerability disclosed on August 12, 2024. Organizations using this software should take immediate steps to upgrade to the latest version to mitigate this risk.

Technical Analysis

The root cause of CVE-2024-7399 lies in improper pathname limitations, which allow attackers to bypass access controls and write files arbitrarily. The attack vector is network-based, meaning that an attacker could exploit this vulnerability remotely without physical access to the system.

The attack complexity is low, requiring minimal technical skills. Privileges required for exploitation are also low, with user interaction not necessary for successful exploitation. The vulnerability can result in high confidentiality, integrity, and availability impacts, as attackers may gain full control over the affected systems.

Risk & Impact Analysis

Organizations using Samsung MagicINFO 9 Server face significant risks due to CVE-2024-7399. The potential for unauthorized file access and modification could lead to severe data breaches, loss of sensitive information, and operational disruptions. The impact on confidentiality, integrity, and availability is substantial, given the nature of the vulnerability.

With the exploitability status high and known exploits available, organizations should assess their exposure and take action to patch the vulnerability as part of their immediate security strategy. Failure to do so could result in exploitation that compromises organizational assets.

The urgency for remediation cannot be overstated. Organizations should prioritize patching immediately to prevent potential attacks and mitigate risks associated with this high-severity vulnerability.
