What is CVE-2020-10560?

The Open Source Social Network (OSSN) prior to version 5.3 is affected by a vulnerability that allows attackers to exploit user-controlled file paths with weak cryptographic methods. By performing a brute-force attack against the SiteKey, an attacker can gain unauthorized access to any file readable by the web server. This includes critical components of the application such as 'ossn_com.php' and 'ossn.lib.upgrade.php', which can lead to further security issues or data exposure.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
