CVE-2013-4865

Vulnerability

Cross-site request forgery (CSRF) vulnerability exists in the upgrade_step2.sh script of MiCasaVerde VeraLite running firmware version 1.5.408. The script does not implement any anti-CSRF tokens or origin validation, allowing an attacker to craft a malicious request that, when executed by an authenticated user, can install arbitrary firmware through the squashfs parameter [1][2][3].

Exploitation

An attacker must trick an authenticated VeraLite administrator or guest user into visiting a crafted webpage or clicking a link while logged into the VeraLite web interface (or the cloud control panel at cp.mios.com). The attacker constructs a request to upgrade_step2.sh with a malicious squashfs parameter pointing to a firmware image under the attacker's control. No additional authentication is needed because the victim's active session is reused [1][2][3].

Impact

Successful exploitation allows an attacker to install arbitrary firmware on the VeraLite device, effectively gaining full control over the home automation controller. This can lead to complete compromise of the device and potentially the connected home automation network, including door locks, security cameras, and other smart home components [1][2][3].

Mitigation

MiCasaVerde has not released a patched firmware version for this vulnerability. The affected firmware version 1.5.408 appears to be the latest for this product line, and the device may be end-of-life. Users are advised to restrict network access to the VeraLite, disable remote management if possible, and ensure that only trusted users have access to the local or cloud-based control panel [1][2][3].
