Vulnerability from variot
Input validation issue in Buffalo BBR-4HG and and BBR-4MG broadband routers with firmware 1.00 to 1.48 and 2.00 to 2.07 allows an attacker to cause the device to become unresponsive via unspecified vectors. BBR-4HG and BBR-4MG provided by BUFFALO INC. are wireless LAN routers. BBR-4HG and BBR-4MG contain multiple vulnerabilities listed below. * Cross-site Scripting (CWE-79) - CVE-2017-10896 * Improper Input Validation (CWE-20) - CVE-2017-10897 Toshitsugu Yoneyama of Mitsui Bussan Secure Directions, Inc. reported this vulnerability to IPA. JPCERT/CC coordinated with the developer under Information Security Early Warning Partnership.The possible impact of each vulnerability is as follows: * An arbitrary script may be executed on the user's web browser If a logged-in user accesses a specially crafted page - CVE-2017-10896 * The device may become unresponsive if an improper input value is set in the administrative page - CVE-2017-10897. Buffalo BBR-4HG and BBR-4MG are both broadband router products of the Buffalo Group in Japan. An attacker could exploit the vulnerability to cause a denial of service (the device could not respond)
