Detailsinfo

A vulnerability was found in Riello NetMan 204 14-2/15-2 and classified as critical. Affected by this issue is an unknown code. The manipulation of the argument VAL0/VAL1 as part of a GET Parameter leads to a credentials management vulnerability. Using CWE to declare the problem leads to CWE-255. Impacted is confidentiality, integrity, and availability. CVE summarizes:

An issue was discovered in Riello NetMan 204 14-2 and 15-2. The issue is with the login script and wrongpass Python script used for authentication. When calling wrongpass, the variables $VAL0 and $VAL1 should be enclosed in quotes to prevent the potential for Bash command injection. Further to this, VAL0 and VAL1 should be sanitised to ensure they do not contain malicious characters. Passing it the username of '-' will cause it to time out and log the user in because of poor error handling. This will log the attacker in as an administrator where the telnet / ssh services can be enabled, and the credentials for local users can be reset. Also, login.cgi accepts the username as a GET parameter, so login can be achieved by browsing to the /cgi-bin/login.cgi?username=-%20a URI.

The weakness was released 07/03/2019. This vulnerability is handled as CVE-2017-6900 since 03/14/2017. Local access is required to approach this attack.
