Yesterday the migration of the OJS system from version 2.3.3.3 to 2.4.8.0 was performed.
In this migration, the image management part of the system is not working.
But before reporting this problem, the system was invaded last night and the problem was solved.
I would like to check with you if you know about any vulnerabilities in the system and what we can do to resolve them.
Can someone help us with the issue of application security and solve this problem?
The attacker is submitting .exe, .php, and .html files. The submission part is in trouble. This routine should be limited to extensions doc, docx, odt, pdf, img and jpg.
Thank you.
