Cudy TR3000 before 2.5.42 contains an OS command injection vulnerability that allows a malicious or compromised ACS to execute commands as root by supplying a crafted InternetGatewayDevice.User.{i}.Password value. Attackers can send a SetParameterValues request with shell metacharacters that obuspa_system.lua concatenates into a luci.util.exec() command string, gaining root command execution.

Cudy TR3000 before 2.5.42 contains an OS command injection vulnerability that allows a malicious or compromised ACS to execute commands as root by supplying an unvalidated InternetGatewayDevice.User.{i}.Username value. Attackers can send a SetParameterValues request with shell metacharacters that set_UserUsername() in obuspa_system.lua passes to os.execute(), gaining root command execution.

Cudy TR3000 before 2.5.42 contains a command injection vulnerability that allows authenticated administrators to execute commands as root via an unvalidated multipart filename in the CBI FileUpload handler. Attackers can upload a valid OpenVPN configuration file through the VPN client config page with a filename containing $() shell substitution, which is passed through Lua %q to /bin/sh -c.

Cudy TR3000 before 2.5.42 contains a command injection vulnerability that allows authenticated administrators to execute commands as root by storing a malicious WireGuard private key. Attackers can save a private_key containing $() shell substitution and call the vpn.export_conf method on the /cgi-bin/luci/rpc/app JSON-RPC endpoint, which passes the key to a wg pubkey shell command.

Cudy TR3000 before 2.5.42 contains a command injection vulnerability that allows authenticated administrators to execute commands as root via the WireGuard server private_key option. Attackers can save a private key containing $() command substitution, which runs when action_wireguards_export() passes it to luci.sys.exec during configuration export.

Cudy TR3000 before 2.5.42 contains a command injection vulnerability in luci/model/cbi/vpn/openvpn/client.lua, which embeds the shellquote()-quoted remote host token of an uploaded OpenVPN configuration inside an already single-quoted sed program run by os.execute(), so the nested quotes terminate the outer quote. Authenticated administrators can upload an .ovpn file whose remote host token contains a semicolon to execute arbitrary commands as root.

Cudy TR3000 before 2.5.42 contains an option injection vulnerability that allows authenticated administrators to inject arbitrary pppd options by embedding quotes and newlines in L2TP credentials. Attackers can submit crafted usernames or passwords to the net.set_wan RPC method, which l2tp.sh writes into a pppd options file, adding options like logfile to the root pppd process.

Cudy TR3000 before 2.5.42 contains a command injection vulnerability that allows authenticated administrators to execute commands as root by injecting newlines into the IPsec keyexchange field of the vpn.set_conf RPC method. Attackers can append a second leftupdown directive to ipsec.conf, which StrongSwan's updown plugin runs as root when an attacker-controlled peer establishes the CHILD_SA.
