TITLE

Genexis GAPS Vulnerable to information disclosure

Trust: 0.8

sources: JVNDB: JVNDB-2017-011783

DESCRIPTION

CPEs used by subscribers on the access network receive their individual configuration settings from a central GAPS instance. A CPE identifies itself by the MAC address of its WAN interface and a certain "chk" value (48bit) derived from the MAC. The algorithm used to compute the "chk" was disclosed by reverse engineering the CPE's firmware. As a result, it is possible to forge valid "chk" values for any given MAC address and therefore receive the configuration settings of other subscribers' CPEs. The configuration settings often contain sensitive values, for example credentials (username/password) for VoIP services. This issue affects Genexis B.V. GAPS up to 7.2. Genexis GAPS Contains an information disclosure vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. GenexisAutomaticProvisioning System (GAPS) is a system of GENEXIS in the Netherlands for automatically configuring routers and networks. An access control vulnerability exists in GAPS 7.2 and earlier. An attacker could use this vulnerability to obtain configuration information (user credentials)
