CVE-2017-8334

Vulnerability

The web management interface on Securifi Almond, Almond+, and Almond 2015 devices running firmware AL-R096 lacks cross-site request forgery (CSRF) protection. The interface provides functionality such as blocking IP addresses, but does not implement any anti-CSRF tokens or referer checks, making it vulnerable to CSRF attacks [1][2].

Exploitation

An attacker can craft a malicious web page or email that, when visited by a user currently authenticated to the device's web management interface, triggers a forged request. The request can perform any action available in the web interface, such as adding or removing IP address blocks, without the user's knowledge or consent. No additional authentication or user interaction beyond visiting the malicious page is required [1][2].

Impact

Successful exploitation allows the attacker to execute arbitrary actions on the device via the web management interface, including modifying network settings, blocking or unblocking IP addresses, and potentially causing denial of service or other configuration changes. The attacker does not gain direct code execution but can manipulate device behavior as if they were the authenticated user [1][2].

Mitigation

As of the publication date (2019-06-18), no firmware update or official patch has been released to address this vulnerability. Users are advised to avoid accessing the web management interface while browsing untrusted websites and to consider network-level protections such as restricting access to the management interface to trusted IP addresses only [1][2].
