The device sends AES encryption keys in cleartext which can be captured by an attacker within the network. With these keys, an attacker can decrypt communications between the management app and the Sight Bulb Pro, potentially gaining access to sensitive information such as network credentials.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-2139500265\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>An attacker could monitor network traffic during the initial setup of the device and capture the unencrypted AES keys. This could be done using a packet sniffing tool like Wireshark:<\/p>\n<pre><code class=\"\" data-line=\"\">$ sudo wireshark -i wlan0 -k -Y &#039;wlan.fc.type_subtype == 0x08&#039;<\/code><\/pre>\n<p>This command starts Wireshark on the wlan0 interface, captures packets, and filters for beacon frames broadcast by the Sight Bulb Pro during setup. The attacker could then analyze the captured traffic for the unencrypted AES keys.<\/p>\n<p><strong>Mitigation<\/strong><\/p>\n<p>Users are advised to apply the vendor patch as soon as it&#8217;s available. In the interim, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. These systems should be configured to monitor for suspicious network traffic and potential exploitation of this vulnerability.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview The Sight Bulb Pro, a popular device in the smart home industry, has been discovered to have a critical vulnerability identified as CVE-2025-6521.
