Genexis

A vulnerability has been identified in Genexis Platinum P4410 router (Firmware P4410-V2–1.41) that allows a local network attacker to achieve Remote Code Execution (RCE) with root privileges. The issue occurs due to improper session invalidation after administrator logout. When an administrator logs out, the session token remains valid. An attacker on the local network can reuse this stale token to send crafted requests via the router’s diagnostic endpoint, resulting in command execution as root.Show less

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.Show less
