CVE-2017-8332

Vulnerability

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 blocking key words passing in the web traffic to prevent kids from watching content that might be deemed unsafe using the web management interface. It appears that the device does not implement any cross-site scripting protection mechanism [1]. This allows an attacker to inject a stored cross-site scripting (XSS) payload via the keyword blocking feature [1].

Exploitation

An attacker can trick a user who is already logged in to the web management interface into executing a stored cross-site scripting payload on the user's browser [1]. The attacker requires the ability to submit the malicious payload through the web interface, which may depend on network access or social engineering to have an authenticated user trigger the stored payload [1][2].

Impact

Successful exploitation allows the attacker to execute any action on the device that is provided by the web management interface, potentially including configuration changes, data exfiltration, or other admin-level operations [1]. The scope of compromise is the full functionality exposed to the authenticated user in the web management interface [1].

Mitigation

No fix or patched firmware version has been identified in the available references [1][2]. As of the publication date (2019-06-18), users are advised to restrict access to the web management interface to trusted users and avoid clicking on untrusted links while logged in. The Almond 2015 device is likely end-of-life (EOL) and may not receive a security update [2].
