    JVNDB-2026-006102

    Vulnerability from jvndb - Published: 2026-03-06 10:31 - Updated:2026-03-06 10:31
    Summary
    Security issues in ESC/POS
    Details
    ESC/POS is a printer control language designed by Seiko Epson Corporation for controlling POS printers and related devices. The following security issues have been identified with ESC/POS. Products implementing ESC/POS need to be designed and operated with consideration of the following security issues: Missing authentication for critical function (CWE-306) ESC/POS does not define any mechanisms for user authentication or command authorization. Consequently, printers accepting ESC/POS commands over a network have no restrictions on connections, allowing commands to be sent from any host on the network. Improper access control (CWE-284) ESC/POS does not define any mechanisms to restrict origins or destinations of communication. Many printers listen for ESC/POS communication on TCP port 9100 by default, potentially allowing access from any host on the network. Cleartext transmission of sensitive information (CWE-319) ESC/POS command transmission does not provide encryption or integrity protection mechanisms, and communicate is performed in plaintext. Consequently, attackers on the same network could be able to intercept or tamper with transmitted data. JPCERT/CC has assigned CVE-2026-23767 to the vulnerability originating from the ESC/POS specification. This document was written by Seiko Epson Corporation and JPCERT/CC. The issue regarding the lack of an authentication mechanism was reported to Seiko Epson Corporation by Michael Cook (FutileSkills), and coordinated by JPCERT/CC.

    JVNDB-2024-009481

    Vulnerability from jvndb - Published: 2024-10-01 14:14 - Updated:2024-11-12 10:25
    Severity
    Summary
    Insecure initial password configuration issue in SEIKO EPSON Web Config
    Details
    Web Config is software that allows users to check the status and change the settings of SEIKO EPSON products, e.g., printers and scanners, via a web browser. In the initial setting no administrative password is set, and when a user connects the device and configures Web Config settings for the first time, the user is requested to set the password. Therefore, when a product is connected to network without the Web Config settings configured, arbitrary password may be set and the device may be operated with an administrative privilege by an attacker (CWE-1188). George Puckett reported this vulnerability to CERT/CC. Requested by CERT/CC, JPCERT/CC coordinated with the developer.
