CVE-2025-53048
📋 TL;DR
This vulnerability in Oracle PeopleSoft Enterprise PeopleTools allows authenticated attackers with low privileges to manipulate data via the Rich Text Editor component. Successful exploitation requires tricking another user into interacting with malicious content, potentially leading to unauthorized data modification or access. Affected versions include PeopleSoft Enterprise PeopleTools 8.60, 8.61, and 8.62.

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could modify critical PeopleSoft data, insert malicious content, or exfiltrate sensitive information through the compromised Rich Text Editor, potentially affecting connected systems due to scope change.
Likely Case
Low-privileged authenticated users could manipulate data they shouldn't have access to, potentially altering configuration, user data, or business information within PeopleSoft.
If Mitigated
With proper access controls and user awareness training, the impact is limited to minor data manipulation within the attacker's authorized scope.
🎯 Exploit Status
Requires low-privilege authentication AND social engineering (human interaction from another user). This combination makes exploitation more complex than purely technical attacks.
