CVE-2024-7700 is a command injection vulnerability identified in the Foreman application, a popular open-source lifecycle management tool used for provisioning and configuring physical and virtual servers. The flaw exists in the 'Host Init Config' template, specifically within the 'Install Packages' field on the 'Register Host' page. This field allows privileged users to specify packages to be installed during host registration. Due to improper neutralization of special elements, an attacker with the necessary privileges can inject arbitrary shell commands into this field. When the generated registration script is executed by a user, these injected commands run with the privileges of the executing user, potentially leading to unauthorized command execution on the host system. The vulnerability requires user interaction, as the malicious commands only execute when the registration script is run, typically by an administrator or operator. The CVSS v3.1 score of 6.5 reflects a medium severity, with the vector indicating local attack vector (AV:L), low attack complexity (AC:L), high privileges required (PR:H), and user interaction needed (UI:R). The impact on confidentiality, integrity, and availability is high, as arbitrary commands could lead to data compromise, system modification, or denial of service. No known exploits have been reported in the wild, but the risk remains significant in environments relying on Foreman for automated host setup. The lack of affected versions and patch links suggests that this is a recently disclosed vulnerability, and users should monitor vendor advisories for updates.

For European organizations, this vulnerability poses a significant risk in IT environments that utilize Foreman for automated provisioning and configuration management. Successful exploitation could allow attackers to execute arbitrary commands during host registration, potentially leading to unauthorized access, data breaches, system tampering, or disruption of services. Given that Foreman is often used in enterprise and data center environments, the impact could extend to critical infrastructure and business operations. The requirement for high privileges and user interaction somewhat limits the attack surface, but insider threats or compromised privileged accounts could exploit this flaw. Additionally, automated deployment pipelines that run registration scripts without sufficient validation could inadvertently execute malicious commands. This could result in widespread compromise across multiple hosts, affecting confidentiality, integrity, and availability of systems and data. The medium severity rating indicates that while the vulnerability is serious, it is not trivially exploitable remotely without privileged access, but the potential damage warrants prompt attention.

To mitigate CVE-2024-7700, European organizations should implement the following specific measures: 1) Immediately review and restrict access to the 'Host Init Config' templates and the 'Install Packages' field to only trusted, highly vetted administrators. 2) Implement strict input validation and sanitization on the 'Install Packages' field to prevent injection of special characters or shell commands. 3) Avoid running generated registration scripts without thorough inspection, especially if sourced from untrusted or less experienced users. 4) Incorporate automated scanning tools to detect suspicious command patterns in configuration templates and scripts before execution. 5) Monitor and audit privileged user activities related to host registration and configuration changes to detect anomalous behavior. 6) Stay updated with Foreman vendor advisories and apply patches or updates as soon as they become available. 7) Consider isolating the execution environment for registration scripts to limit potential damage from command injection. 8) Educate administrators about the risks of command injection and the importance of cautious script execution. These targeted actions go beyond generic advice by focusing on controlling privileged access, input validation, and operational best practices specific to Foreman’s host registration process.
