CVE-2017-8328 in Almond
Summary
by MITRE
An issue was discovered on Securifi Almond, Almond+, and Almond 2015 devices with firmware AL-R096. The device provides a user with the capability of changing the administrative password for the web management interface. It seems that the device does not implement any cross site request forgery protection mechanism which allows an attacker to trick a user who is logged in to the web management interface to change a user's password. Also this is a systemic issue.

The vulnerability identified as CVE-2017-8328 affects Securifi Almond, Almond+, and Almond 2015 devices running firmware version AL-R096, representing a critical security flaw in IoT device management interfaces. This vulnerability stems from the absence of cross site request forgery protection mechanisms within the web management interface, creating a systemic weakness that impacts multiple device models from the same manufacturer. The flaw specifically targets the administrative password change functionality, which is a fundamental security control for device access and management.
The technical implementation of this vulnerability involves the lack of anti-CSRF tokens or similar protective mechanisms in the web interface's password change endpoint. When an authenticated user accesses the device's management interface, their session remains active and trusted by the system. An attacker can exploit this by crafting malicious web pages or links that, when clicked by the logged-in user, automatically submit password change requests to the device's management interface without the user's knowledge or explicit consent. This attack vector leverages the trust relationship between the user's browser and the device's web interface, making it particularly dangerous as it requires no authentication credentials from the attacker.
The operational impact of this vulnerability extends beyond individual device compromise to represent a broader security failure that affects the entire Securifi product line. Once exploited, the attacker gains complete administrative control over the affected device, potentially enabling them to modify network configurations, install malicious firmware, or use the device as a pivot point for attacking other systems on the local network. The systemic nature of this issue means that all devices running the vulnerable firmware version are equally susceptible, creating a widespread security risk for users who may have multiple devices in their network infrastructure. This vulnerability directly violates the principle of least privilege and demonstrates poor security implementation practices in IoT device development.
Mitigation strategies for CVE-2017-8328 should include immediate firmware updates from Securifi to address the CSRF protection deficiency, along with network segmentation to limit the potential damage from compromised devices. Users should also implement strong network monitoring to detect unusual administrative activity and consider disabling unnecessary web management interfaces when not actively needed. From a security standards perspective, this vulnerability aligns with CWE-352 which specifically addresses Cross-Site Request Forgery weaknesses, and it maps to ATT&CK technique T1078 which covers valid accounts and privilege escalation. Organizations should also implement multi-factor authentication where possible and regularly audit their IoT device configurations to ensure proper security controls are in place. The vulnerability serves as a reminder of the critical importance of implementing proper CSRF protections in web applications and interfaces, particularly in devices where unauthorized access could lead to significant security implications.
