GNU SASL libgsasl server-side read-out-of-bounds with malicious authenticated GSS-API client

An issue was discovered in DSK DSKNet 2.16.136.0 and 2.17.136.5. It mishandles access control. This allows a remote attacker to access account information pages (including personal data) without being authenticated. The collected information includes the badge numbers that operate as user login names. They have a PIN code. The PIN code is 4 digits and thus can be guessed in 10000 brute force attempts.

An issue was discovered in DSK DSKNet 2.16.136.0 and 2.17.136.5. The Touch settings allow unrestricted file upload (and consequently Remote Code Execution) via PDF upload with PHP content and a .php extension. The attacker must hijack or obtain privileged user access to the Parameters page in order to exploit this issue. (That can be easily achieved by exploiting the Broken Access Control with further Brute-force attack or SQL Injection.) The uploaded file is stored within the database and copied to the sync web folder if the attacker visits a certain .php?action= page.
