An issue was found in upload.php on the Ruijie EG-2000 series gateway. A parameter passed to the class UploadFile is mishandled (%00 and /var/./html are not checked), which can allow an attacker to upload any file to the gateway. This affects EG-2000SE EG_RGOS 11.9 B11P1.

An issue was found on the Ruijie EG-2000 series gateway. There is a newcli.php API interface without access control, which can allow an attacker (who only has web interface access) to use TELNET commands and/or show admin passwords via the mode_url=exec&command= substring. This affects EG-2000SE EG_RGOS 11.9 B11P1.

An issue was found on the Ruijie EG-2000 series gateway. There is a buffer overflow in client.so. Consequently, an attacker can use login.php to login to any account, without providing its password. This affects EG-2000SE EG_RGOS 11.1(1)B1.

An issue was found on the Ruijie EG-2000 series gateway. An attacker can easily dump cleartext stored passwords in /data/config.text with simple XORs. This affects EG-2000SE EG_RGOS 11.1(1)B1.
