### Description:
The AHSS-PHP (by: oretnom23 ) v1.0 is vulnerable in the application
/scheduler/classes/Login.php to remote SQL-Injection-Bypass-Authentication
+ XSS-Stored Hijacking PHPSESSID
- m0re info:
https://portswigger.net/support/using-sql-injection-to-bypass-authentication.

The parameter (username) from the login form is not protected correctly and
there is no security and escaping from malicious payloads.
When the user will sending a malicious query or malicious payload to the
MySQL server he can bypass the login credentials and take control of the
administer account.
2. XSS - Stored PHPSESSID Vulnerable
- The vulnerable XSS app: is "manage_assembly", parameters: "room_name"
"location" and "description"
After the successful SQL injection, the malicious user can be storing an
XSS payload whit who can take the
active PHPSESSID session.
3. remote PHPSESSID - Injection
- After the successful XSS attack the malicious user can take control of
the administrative account of the system from everywhere
by using the PHPSESSID, and then he can make a lot of bad things!

-------------------------------------------------------------------
### CONCLUSION: This vendor must STOP creating all these broken projects
and vulnerable software programs, probably he is not a developer!
