    CVE-2019-14456 (GCVE-0-2019-14456)

    Vulnerability from nvd – Published: 2019-07-31 20:17 – Updated: 2024-08-05 00:19
    VLAI
    Summary
    Opengear console server firmware releases prior to 4.5.0 have a stored XSS vulnerability related to serial port logging. If a malicious user of an external system (connected to a serial port on an Opengear console server) sends crafted text to a serial port (that has logging enabled), the text will be replayed when the logs are viewed. Exploiting this vulnerability requires access to the serial port and/or console server.
    Severity
    No CVSS data available.

    Pre-Auth Heap Buffer Overflow in the Multipart Request
    Summary
    Heap-based buffer overflow in Opengear IM72XX, CM71XX, and ACM70XX firmware versions 4.8.0 through 5.5.2 on console server appliances allows an unauthenticated remote attacker to crash the index.cgi process via a crafted multipart/form-data POST request containing an overlong Content-Disposition name field.

    CVE-2019-14456 (GCVE-0-2019-14456)

    Vulnerability from cvelistv5 – Published: 2019-07-31 20:17 – Updated: 2024-08-05 00:19
    VLAI
    Summary
    Opengear console server firmware releases prior to 4.5.0 have a stored XSS vulnerability related to serial port logging. If a malicious user of an external system (connected to a serial port on an Opengear console server) sends crafted text to a serial port (that has logging enabled), the text will be replayed when the logs are viewed. Exploiting this vulnerability requires access to the serial port and/or console server.
    Severity
    No CVSS data available.
