Official Description
A stored cross-site scripting vulnerability in the Sources UI in Proofpoint Threat Response/ Threat Response Auto Pull (PTR/TRAP) could allow an authenticated administrator on an adjacent network to replace the image file with an arbitrary MIME type. This could result in arbitrary javascript code execution in an admin context. All versions prior to 5.10.0 are affected.
Technical Analysis
CVE-2023-2819 requires adjacent network access, limiting remote exploitation but still posing risk in shared or local network environments.
Exploitation requires high privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
From a weakness classification perspective (CWE-79): Cross-site scripting (XSS) vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users.
