Genexis Platinum-4410 P4410-V2-1.31A - 'start_addr' Persistent Cross-Site Scripting

Genexis Platinum-4410 P4410-V2-1.31A contains a stored cross-site scripting vulnerability in the 'start_addr' parameter of the Security Management interface. Attackers can inject malicious scripts through the start source address field that will persist and trigger for privileged users when they access the security management page.

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.

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 PLATINUM 4410 2.1 P4410-V2-1.28 devices allow remote attackers to execute arbitrary code via shell metacharacters to sys_config_valid.xgi, as demonstrated by the sys_config_valid.xgi?exeshell=%60telnetd%20%26%60 URI.

An authentication bypass vulnerability on Genexis Platinum-4410 v2.1 P4410-V2 1.28 devices allows attackers to obtain cleartext credentials from the HTML source code of the cgi-bin/index2.asp URI.

Cross site request forgery (CSRF) in Genexis Platinum 4410 V2-1.28, allows attackers to cause a denial of service by continuously restarting the router.

Genexis Platinum-4410 P4410-V2-1.28 devices allow stored XSS in the WLAN SSID parameter. This could allow an attacker to perform malicious actions in which the XSS popup will affect all privileged users.

UPNP Service listening on port 5555 in Genexis Platinum 4410 Router V2.1 (P4410-V2–1.34H) has an action 'X_GetAccess' which leaks the credentials of 'admin', provided that the attacker is network adjacent.

A specific router allows changing the Wi-Fi password remotely. Genexis Platinum 4410 V2-1.28, a compact router generally used at homes and offices was found to be vulnerable to Broken Access Control and CSRF which could be combined to remotely change the WIFI access point’s password.
