A flaw in the provisioning process of the Prolink 13A Smart Plug allows an attacker to feed a specially crafted packet that can halt the device’s operation or cause it to connect to an attacker‑controlled endpoint. The resulting denial of service disrupts the plug’s normal functionality, while the unexpected outbound link can enable the attacker to exploit the device as a pivot for further attacks, categorized as CWE‑20.

The affected device is the Prolink 13A Smart Plug model DS‑3202M‑UKv3 Wi‑Fi, running the mEzee application version 2.6.7. No other vendor or product variants are listed as impacted in the current data.

The CVSS base score of 7.5 indicates a high‑severity vulnerability; the EPSS score of <1% indicates a very low exploitation probability, and the flaw is not listed in CISA’s KEV catalog, suggesting that mass exploitation has not yet been observed. An attacker would normally need to transmit the forged packet during the device’s provisioning phase, which typically occurs on the local network or device‑to‑controller channel, implying that physical proximity or local‑network access is required. The description does not detail a public exploit, so the risk is primarily theoretical until an exploit or additional user‑reports emerge.
