CVE-2025-5160 is a path traversal vulnerability identified in the H3C SecCenter SMP-E1114P02 product, specifically affecting versions up to 20250513. The vulnerability resides in the Download function of the /packetCaptureStrategy/download endpoint, where the 'Name' argument is improperly sanitized. This flaw allows an attacker to manipulate the 'Name' parameter to traverse directories on the server's filesystem, potentially accessing unauthorized files outside the intended directory scope. The vulnerability can be exploited remotely without requiring user interaction or authentication, which significantly lowers the barrier for exploitation. Although the CVSS 4.0 base score is 5.3 (medium severity), the vulnerability's impact on confidentiality is limited but non-negligible, as it could allow disclosure of sensitive files. The integrity and availability impacts are rated low or none. The vendor was notified but did not respond or provide a patch, and while no known exploits are currently reported in the wild, public disclosure of the exploit code increases the risk of exploitation. The vulnerability is notable because path traversal can lead to information disclosure, which may be leveraged for further attacks or reconnaissance within a compromised network environment.

For European organizations using H3C SecCenter SMP-E1114P02, this vulnerability poses a moderate risk primarily related to confidentiality breaches. Unauthorized access to sensitive configuration files, logs, or captured packet data could expose internal network details, user credentials, or other critical information. This exposure could facilitate lateral movement or escalation in targeted attacks. Given the remote and unauthenticated nature of the exploit, attackers could scan and exploit vulnerable devices at scale, potentially impacting network security monitoring and incident response capabilities. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, and critical infrastructure, may face compliance risks if sensitive data is disclosed. However, the absence of known active exploitation and the medium severity rating suggest that while the threat is real, it may not currently be widespread or catastrophic. Nonetheless, the lack of vendor response and patch availability increases the urgency for organizations to implement compensating controls.

Since no official patch or update is available from the vendor, European organizations should implement several specific mitigations: 1) Restrict network access to the H3C SecCenter SMP-E1114P02 management interfaces by applying strict firewall rules, allowing only trusted IP addresses and administrative networks to connect. 2) Employ web application firewalls (WAFs) or intrusion prevention systems (IPS) with custom rules to detect and block path traversal patterns in HTTP requests targeting the /packetCaptureStrategy/download endpoint. 3) Conduct regular audits and monitoring of server logs to detect anomalous requests or attempts to exploit the 'Name' parameter. 4) If feasible, isolate the vulnerable device within a segmented network zone to limit potential lateral movement. 5) Consider deploying virtual patching techniques or reverse proxies that sanitize input parameters before they reach the vulnerable application. 6) Plan for replacement or upgrade of the affected product once a vendor patch or alternative solution becomes available. 7) Educate security teams about this vulnerability to ensure rapid detection and response to any exploitation attempts.
