Web Management Portal
1. Reflected XSS – multiple urls, parameters
2. Stored XSS – multiple urls, parameters
3. Weak Credentials Management
The device comes configured with four (4) login accounts:
– admin / 1
– user / 1
– alg / 1
– telem / 1
– These passwords do not meet even basic security criterion.
– To further make it easier for attacker(s), the application design does not provide the users, any option to change their own passwords in device management portal. Only ‘root’ can change passwords for all other accounts. (AFAIK)
4. Undocumented root account
In addition to the above four documented login accounts, there is a ‘root’ superuser account:
– root / root
– root account details are not documented in the device administration guide or manuals
– root account has multiple, additional functions accessible like user management
5. Sensitive Information stored in clear-text
Sensitive information, specifically, the account passwords, are all stored and shown in clear-text.
Additionally, specific non-root, non-privileged users can access complete device configuration file, which contains clear-text passwords and other config information. This flaw can be used to gain privileged access to the device.
6. Vulnerable to Cross-Site Request Forgery
There is no CSRF Token generated per page and / or per (sensitive) function. Successful exploitation of this vulnerability can allow silent execution of unauthorized actions on the device such as configuration parameter changes, and saving modified configuration.
7. Sensitive information leakage
Every time ‘root’ logs in, a GET request is made to a specific url to access password configuration file.
1. Access Control Flaws
By default, password authentication is not enabled on Telnet access (AFAIK).
– This access gives superuser-level access to device
– Access to the device provides detailed info on application, configuration, device file system, databases (including Energy & billing), consumption, Statistics, network information, as well as clear-text creds (FTP)
– Easy vector to device & data compromise
