What is CVE-2020-27358?

A vulnerability exists in the REDCap platform that allows non-privileged users to access and export conversation threads from other users. This occurs through a flaw in the messenger's CSV export feature, enabling an attacker to manipulate the thread_id parameter in requests sent to the 'messenger_download_csv.php' endpoint. By leveraging this weakness, sensitive information may be exposed, putting user data at risk. It is crucial for REDCap users to be aware of this vulnerability and take proactive measures to secure their systems.

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.
