CVE-2024-13982 is a path traversal vulnerability classified under CWE-22, found in the SPON IP Network Broadcast System developed by Changsha SPON Communication Technology Co. Ltd. The vulnerability exists in the rj_get_token.php endpoint, specifically in the handling of the jsondata[url] POST parameter. Due to insufficient validation, attackers can craft malicious requests that traverse directories on the server filesystem, enabling arbitrary file reads. This flaw is exploitable remotely without any authentication or user interaction, making it highly accessible to attackers. The arbitrary file read capability can lead to exposure of sensitive files such as configuration files, credential stores, or internal application logic, which can facilitate further attacks like privilege escalation or lateral movement. The affected version range is unspecified, implying all versions might be vulnerable. The CVSS 4.0 base score is 8.7, reflecting a high severity with network attack vector, low attack complexity, no privileges or user interaction required, and a high impact on confidentiality. No patches or official mitigations have been published yet, and no active exploitation has been reported. This vulnerability poses a significant risk to organizations relying on the SPON IP Network Broadcast System for digital audio transmission, especially those with exposed or poorly segmented network environments.

For European organizations, the impact of CVE-2024-13982 can be substantial. The ability to read arbitrary files remotely without authentication threatens the confidentiality of sensitive data, including system configurations and credentials. Exposure of such information can lead to further exploitation, including unauthorized access, data breaches, and disruption of broadcast services. Organizations operating critical media infrastructure or public communication networks may face operational disruptions and reputational damage. Additionally, attackers could leverage disclosed credentials or internal logic to pivot within networks, potentially compromising other systems. The lack of available patches increases the window of exposure, making proactive mitigation essential. Given the strategic importance of broadcast systems in public information dissemination, especially in times of crisis, this vulnerability could have broader societal impacts if exploited.

1. Implement strict input validation and sanitization on the jsondata[url] parameter to prevent directory traversal sequences such as '../'. 2. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious path traversal payloads targeting rj_get_token.php. 3. Restrict access to the SPON IP Network Broadcast System interfaces to trusted network segments using network segmentation and access control lists (ACLs). 4. Monitor server logs and network traffic for anomalous POST requests to the vulnerable endpoint, focusing on unusual file path patterns. 5. Conduct regular security assessments and penetration tests to identify similar vulnerabilities. 6. Engage with the vendor for timely patch releases and apply updates promptly once available. 7. Consider deploying file integrity monitoring to detect unauthorized file access or changes. 8. Limit the privileges of the web server process to minimize the impact of arbitrary file reads. 9. If possible, isolate the broadcast system from the internet or untrusted networks to reduce exposure. 10. Educate security teams on this specific vulnerability to improve detection and response capabilities.
