Summary
by MITRE • 03/11/2026
Hisilicon HiIpcam V100R003 contains a directory traversal vulnerability that allows unauthenticated attackers to access sensitive configuration files by exploiting directory listing in the cgi-bin directory. Attackers can request the getadslattr.cgi endpoint to retrieve ADSL credentials and network configuration parameters including usernames, passwords, and DNS settings.

The CVE-2019-25465 vulnerability represents a critical directory traversal flaw in Hisilicon HiIpcam V100R003 devices that fundamentally compromises network security through improper input validation. This vulnerability exists within the web interface's cgi-bin directory where the system fails to properly sanitize user-supplied input when processing requests to the getadslattr.cgi endpoint. The flaw allows attackers to manipulate file paths through crafted HTTP requests, enabling unauthorized access to sensitive system configuration files that should remain protected from external inspection.
This directory traversal vulnerability directly maps to CWE-22 - Improper Limitation of a Pathname to a Restricted Directory, which is a fundamental weakness in input validation and path handling mechanisms. The vulnerability operates by exploiting the lack of proper path normalization and validation checks within the web application's request processing pipeline. When an attacker submits a malicious request to the getadslattr.cgi endpoint, the system processes the input without adequate sanitization, allowing directory traversal sequences such as ../ to navigate outside the intended directory structure and access restricted configuration files.
The operational impact of this vulnerability is severe as it provides attackers with access to critical network credentials and configuration parameters that can be leveraged for further exploitation. The retrieved information includes ADSL usernames and passwords, which can be used to establish unauthorized network connections and potentially gain access to upstream network resources. Additionally, DNS settings and other network configuration parameters expose the internal network topology and can facilitate advanced attack vectors such as man-in-the-middle attacks or lateral movement within the network infrastructure. The unauthenticated nature of this vulnerability means that any attacker with network access can exploit it without requiring prior credentials or authentication.
From a threat modeling perspective, this vulnerability aligns with ATT&CK technique T1083 - File and Directory Discovery, as it enables attackers to enumerate and access sensitive files within the device's file system. The vulnerability also supports credential access patterns through T1075 - Pass the Hash and T1550 - Use Alternate Authentication Material, as the exposed credentials can be used for network authentication. The attack chain typically begins with reconnaissance to identify vulnerable devices followed by exploitation of this directory traversal flaw to extract sensitive information. Network segmentation and proper access controls could mitigate the impact, but the vulnerability's presence in embedded network devices often makes remediation challenging due to limited update capabilities and the device's role in network infrastructure.
The recommended mitigations for this vulnerability include immediate firmware updates from Hisilicon to address the directory traversal flaw, implementation of network access controls to restrict access to the cgi-bin directory, and deployment of network monitoring solutions to detect anomalous requests to the getadslattr.cgi endpoint. Additionally, network administrators should consider implementing web application firewalls to filter malicious directory traversal attempts and establish regular security assessments to identify similar vulnerabilities in other network devices. The vulnerability also highlights the importance of proper input validation and secure coding practices in embedded systems, particularly those handling network configuration data that could expose sensitive network parameters to unauthorized parties.
