CVE-2020-15809 in HMP350
Summary
by MITRE • 03/24/2021
spxmanage on certain SpinetiX devices allows requests that access unintended resources because of SSRF and Path Traversal. This affects HMP350, HMP300, and DiVA through 4.5.2-1.0.36229; HMP400 and HMP400W through 4.5.2-1.0.2-1eb2ffbd; and DSOS through 4.5.2-1.0.2-1eb2ffbd.

The vulnerability CVE-2020-15809 represents a critical security flaw in SpinetiX devices that combines server-side request forgery with path traversal techniques to enable unauthorized access to sensitive system resources. This vulnerability specifically affects the spxmanage component across multiple device models including HMP350, HMP300, DiVA systems, HMP400, HMP400W, and DSOS devices. The issue stems from inadequate input validation and improper resource access controls within the device management interface, creating a pathway for attackers to bypass normal security restrictions and access unintended system components.
The technical implementation of this vulnerability leverages both server-side request forgery and path traversal mechanisms to manipulate the application's resource access patterns. Attackers can craft malicious requests that exploit the lack of proper validation in the spxmanage service, allowing them to traverse file system paths and access resources that should be restricted to authorized administrative users. This dual approach creates a particularly dangerous attack vector as it combines the ability to make arbitrary requests to internal systems with the capability to navigate file system structures beyond the intended scope of the application's access controls. The vulnerability affects specific firmware versions of SpinetiX devices, with the impacted releases including various iterations up to 4.5.2-1.0.36229 and 4.5.2-1.0.2-1eb2ffbd, indicating that this issue has been present across multiple firmware releases and affects a broad range of networked video processing equipment.
The operational impact of this vulnerability extends beyond simple unauthorized access to encompass potential system compromise and data exposure across critical network infrastructure. Devices affected by this vulnerability serve as central management points for video processing and network operations, making them attractive targets for adversaries seeking to gain control over surveillance systems, network monitoring capabilities, or access to sensitive video feeds. The vulnerability could enable attackers to access system configuration files, administrative credentials, or other sensitive operational data that could be used for further attacks or to disrupt critical services. Additionally, the exposure of unintended resources could provide attackers with information about the internal network topology, system configurations, or other sensitive operational details that could facilitate more sophisticated attacks. This vulnerability particularly impacts industrial and commercial video surveillance systems where these devices operate in networked environments where unauthorized access could have significant consequences for security operations and privacy protection.
Organizations affected by CVE-2020-15809 should prioritize immediate firmware updates from SpinetiX to address the vulnerability, as this represents a critical security risk that could lead to complete system compromise. The recommended mitigations include implementing network segmentation to limit access to affected devices, deploying network monitoring solutions to detect suspicious requests targeting the spxmanage service, and conducting thorough security assessments of all affected systems. The vulnerability aligns with CWE-918, which covers server-side request forgery, and CWE-22, which addresses path traversal, both of which are categorized under the ATT&CK framework as techniques for privilege escalation and defense evasion. Security teams should also consider implementing web application firewalls to filter malicious requests targeting the vulnerable spxmanage interface and establish monitoring procedures to detect unauthorized access attempts to system resources. Given the nature of the affected devices, which are typically deployed in security-critical environments, organizations should also review their access control policies and ensure that only authorized personnel have access to management interfaces for these systems. The vulnerability demonstrates the importance of proper input validation and resource access controls in networked devices, particularly those that handle sensitive operational data in industrial control systems and security infrastructure environments.
