Product: openeclass
Download: https://github.com/gunet/openeclass
Vunlerable Version: Release_3.5.4 and probably prior
Tested Version: Release_3.5.4
Author: ADLab of Venustech

Advisory Details:
Multiple Cross-Site Scripting (XSS) were discovered in “openeclass Release_3.5.4”, which can be exploited to execute arbitrary code.
The vulnerabilities exist due to insufficient filtration of user-supplied data in multiple parameters passed to the “openeclass-master/modules/tc/webconf/webconf.php” URL. An attacker could execute arbitrary HTML and script code in a browser in the context of the vulnerable website.
The exploitation examples below use the "alert()" JavaScript function to see a pop-up messagebox:
Poc:
(1)
http://localhost/.../openeclass-master/modules/tc/webconf/webconf.php?meeting_id=%22%3E%3Cscript%3Ealert(1);%3C/script%3E%3C%22
(2)
http://localhost/.../openeclass-master/modules/tc/webconf/webconf.php?user=%22;%3C/script%3E%3Cscript%3Ealert(1);%3C/script%3E%3Cscript%3E
