CVE-2025-15082 is an information disclosure vulnerability identified in the TOZED ZLT M30s device series, affecting all firmware versions up to 1.47. The vulnerability resides in an unspecified function within the /reqproc/proc_post file of the device's Web Management Interface. By manipulating the 'goformId' argument in HTTP requests, an attacker can remotely trigger unintended information disclosure. The vulnerability requires no authentication, user interaction, or privileges, and can be exploited over the network, making it highly accessible to attackers. The disclosed CVSS 4.0 score of 6.9 reflects a medium severity level, primarily due to the lack of integrity or availability impact but significant confidentiality concerns. The vendor was informed early but has not issued any patches or advisories, increasing the risk of exploitation. Although no known exploits in the wild have been reported yet, the public availability of exploit code raises the likelihood of imminent attacks. The vulnerability could expose sensitive configuration data or internal device information, potentially facilitating further compromise or lateral movement within affected networks. The broad range of affected versions indicates a long-standing issue, emphasizing the need for immediate defensive measures. Given the device's role in network management, exploitation could undermine the security posture of organizations relying on these devices for critical infrastructure management.

For European organizations, the impact of CVE-2025-15082 can be significant, especially for those deploying TOZED ZLT M30s devices in network management or security-critical roles. Information disclosure could reveal sensitive configuration details, credentials, or internal network topology, enabling attackers to plan more sophisticated intrusions or escalate privileges. This is particularly concerning for sectors such as telecommunications, energy, finance, and government, where network devices are integral to operational continuity and data protection. The lack of vendor response and patches increases exposure time, raising the risk of exploitation. Additionally, since the vulnerability is remotely exploitable without authentication, attackers can target these devices directly from the internet or internal networks if adequate segmentation is not enforced. This could lead to breaches of confidentiality, potential regulatory non-compliance under GDPR if personal data is indirectly exposed, and reputational damage. The medium severity rating suggests that while the vulnerability does not directly impact device integrity or availability, the confidentiality breach alone can have cascading effects on organizational security.

Given the absence of vendor patches, European organizations should implement compensating controls to mitigate the risk from CVE-2025-15082. First, restrict network access to the Web Management Interface of TOZED ZLT M30s devices by implementing strict firewall rules and access control lists (ACLs), allowing only trusted management hosts to connect. Deploy network segmentation to isolate these devices from general user networks and the internet. Enable and monitor logging on these devices and network infrastructure to detect anomalous requests targeting the 'goformId' parameter or unusual HTTP POST activity. Use intrusion detection/prevention systems (IDS/IPS) with custom signatures to identify exploitation attempts. Consider deploying web application firewalls (WAF) in front of management interfaces to filter malicious input. If possible, disable the Web Management Interface or restrict it to out-of-band management networks. Conduct regular vulnerability scans and penetration tests focusing on these devices to identify exploitation attempts. Finally, maintain an inventory of affected devices and prepare for rapid patch deployment once the vendor releases a fix or consider alternative devices with better security support if feasible.
