CVE-2024-48747 is a vulnerability identified in alist-tvbox version 1.7.1 that permits a remote attacker to execute arbitrary code through the /atv-cli file. The vulnerability is classified under CWE-77, indicating a command injection flaw. This means that the application improperly sanitizes or validates input passed to system commands, allowing an attacker to inject malicious commands. Exploitation requires the attacker to have high privileges (PR:H) and user interaction (UI:R), suggesting that the attacker must authenticate and trick a user into triggering the exploit. The attack vector is network-based (AV:N), meaning the attacker can exploit the vulnerability remotely over the network. The CVSS v3.1 base score is 6.8, reflecting medium severity, with high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). No patches or known exploits are currently available, but the vulnerability’s presence in a network-exposed device like alist-tvbox poses a significant risk. The lack of affected versions specified suggests the vulnerability may impact all or multiple versions around v1.7.1. The vulnerability’s exploitation could allow attackers to execute arbitrary commands on the device, potentially leading to full system compromise, data theft, or disruption of service. The /atv-cli endpoint is the attack surface, and securing or disabling this interface is critical. The vulnerability was reserved in early October 2024 and published in November 2024, indicating recent discovery and disclosure.

The potential impact of CVE-2024-48747 is significant for organizations deploying alist-tvbox devices, particularly in environments where these devices are network-accessible. Successful exploitation could lead to arbitrary code execution, allowing attackers to take full control of the device, access sensitive data, disrupt services, or pivot to other network assets. This compromises confidentiality, integrity, and availability. Given the device’s role as a TV box, it may be used in consumer, enterprise, or industrial IoT contexts, increasing the attack surface. The requirement for authentication and user interaction reduces the ease of exploitation but does not eliminate risk, especially in environments with weak access controls or social engineering vulnerabilities. Organizations relying on alist-tvbox for media streaming or other services may face service outages or data breaches. The absence of patches increases the window of exposure. Attackers could use this vulnerability to establish persistent footholds or launch further attacks within internal networks. The impact extends to privacy violations and potential regulatory compliance issues if sensitive data is exposed.

To mitigate CVE-2024-48747, organizations should immediately restrict network access to the /atv-cli endpoint by implementing firewall rules or network segmentation to limit exposure. Strong authentication mechanisms should be enforced to prevent unauthorized access. Input validation and sanitization should be applied to any commands or parameters processed by the /atv-cli interface to prevent command injection. Monitoring and logging of access to the /atv-cli file should be enabled to detect suspicious activity. Until an official patch is released, consider disabling or removing the /atv-cli functionality if it is not essential. Conduct user awareness training to reduce the risk of social engineering attacks that could facilitate user interaction exploitation. Regularly check for updates from the vendor and apply patches promptly once available. Employ intrusion detection/prevention systems (IDS/IPS) to identify attempts to exploit this vulnerability. Perform security assessments and penetration testing focused on this attack vector to identify and remediate weaknesses.
