Title
Physical UART Access Leading to an Unauthenticated Root Shell in TP-Link Kasa EC70 and EC71
Summary
Kasa EC70 v4
and EC71 v4 do not logically disable the production debug interface at the
firmware or chip level and do not lock the bootloader. Although the debug traces are physically
severed during manufacturing, an attacker with physical access can restore the
connection, interrupt the boot process, and manipulate boot parameters to enter
a non-standard initialization path that exposes an unauthenticated root shell
during startup.
Successful exploitation may allow an
attacker with physical access to obtain root-level command access during device
startup, resulting in loss of confidentiality, integrity, and availability for
the affected device. Exploitation requires device disassembly, restoration of
the severed debug connection, and manipulation of the boot process.

Title
Hardcoded Cryptographic Key Information Disclosure Vulnerability on TP-Link Kasa EC70 and EC71
Summary
Kasa EC71 v4 and EC70 v4 firmware contains a static cryptographic private key stored in a read-only filesystem
that is shared across devices. An
attacker with access to the firmware image can extract the embedded key.
Successful
exploitation may allow an unauthenticated attacker on the same network to use
this key in the web management service, compromising the confidentiality of
encrypted communications. This may enable passive decryption of traffic or
active man-in-the-middle (MITM) attacks

Summary
Kasa EC70 v4
and EC71 v4 do not logically disable the production debug interface at the
firmware or chip level and do not lock the bootloader. Although the debug traces are physically
severed during manufacturing, an attacker with physical access can restore the
connection, interrupt the boot process, and manipulate boot parameters to enter
a non-standard initialization path that exposes an unauthenticated root shell
during startup.
Successful exploitation may allow an
attacker with physical access to obtain root-level command access during device
startup, resulting in loss of confidentiality, integrity, and availability for
the affected device. Exploitation requires device disassembly, restoration of
the severed debug connection, and manipulation of the boot process.

Title
Information Disclosure Vulnerability in Local Discovery Response in TP-Link Kasa EC70 and EC71
Summary
An information disclosure vulnerability was identified in TP-Link Kasa EC70 v4 and EC71 v4 in the local discovery mechanism, which exposes
sensitive geolocation information without requiring authentication. This issue
allows an attacker on the same local network to retrieve geolocation-related
data through crafted responses.
The
vulnerability impacts confidentiality only, with no evidence of integrity of
availability impact.

Title
Hardcoded Cryptographic Key Information Disclosure Vulnerability on TP-Link Kasa EC70 and EC71
Summary
Kasa EC71 v4 and EC70 v4 firmware contains a static cryptographic private key stored in a read-only filesystem
that is shared across devices. An
attacker with access to the firmware image can extract the embedded key.
Successful
exploitation may allow an unauthenticated attacker on the same network to use
this key in the web management service, compromising the confidentiality of
encrypted communications. This may enable passive decryption of traffic or
active man-in-the-middle (MITM) attacks
