Description

DEEBOT PRO M1 and DEEBOT PRO K1VAC use wget command with server certificate validation disabled. A man-in-the-middle attack may allow to obtain and/or alter communications of the affected products. As a result, arbitrary code may be executed with the administrative privilege.

  "executiveSummary": "The identified vulnerability involves insecure configuration practices within the DEEBOT PRO M1 and DEEBOT PRO K1VAC products, specifically related to the execution of the wget command with server certificate validation explicitly disabled. This critical security oversight introduces a significant vulnerability class involving broken transport layer security and improper certificate validation. The primary impact of this flaw is the exposure of network communications to interception and tampering, enabling malicious actors to execute arbitrary code with administrative privileges on the target devices.\nAffected systems comprise the DEEBOT PRO M1 and DEEBOT PRO K1VAC robotic devices. The risk implications are severe, as an adversary positioned on the network path can compromise the confidentiality and integrity of device communications, leading to complete device takeover. Attacker capabilities in this context include the interception of sensitive data, modification of transit payloads, and injection of malicious binaries. Exploitation requirements necessitate a network positioning capable of intercepting traffic, such as through an active Man-in-the-Middle (MitM) attack vector on the local network or routing path.",
  "technicalDetails": "The root cause of this security deficit stems from the invocation of the wget utility with command-line flags that disable Transport Layer Security (TLS) or Secure Sockets Layer (SSL) certificate verification, such as ignoring invalid certificates or disabling peer validation entirely. The vulnerable component is the internal firmware mechanism or update script utilizing wget to fetch external resources, packages, or updates over the network.\nExploitation occurs when an attacker executes a Man-in-the-Middle (MitM) attack against the affected DEEBOT PRO M1 or DEEBOT PRO K1VAC units. Because the underlying application logic disables server certificate validation, the system fails to cryptographically verify the authenticity of the remote server or the validity of the presented X.509 certificate. Consequently, the device trusts any arbitrary server responding to the wget request, regardless of whether the certificate is self-signed, expired, revoked, or issued by an untrusted certificate authority.\nThe step-by-step attack flow proceeds as follows: First, the attacker positions themselves on the network path between the affected DEEBOT product and the intended update or resource server. Second, the DEEBOT device initiates a network retrieval operation using the insecurely configured wget command. Third, the attacker intercepts the connection attempt and presents a forged or malicious SSL/TLS certificate. Fourth, because certificate validation is disabled, the DEEBOT device establishes the encrypted or unverified TLS session with the attacker's infrastructure without raising validation errors. Fifth, the attacker delivers a malicious payload or altered communication stream in response to the wget request. Finally, the device processes the retrieved data, resulting in the execution of arbitrary code under administrative privileges due to the lack of input verification and the elevated execution context of the update mechanism."
