Privilege escalation via stored Activity log XSS
Published Oct 27, 2023 · Updated Sep 12, 2024
Stored XSS in VERMEG AgileReporter 21.3 allows remote authenticated users to gain privileges through a crafted Activity log comment. The Add Comment action accepts an XSS payload into the Activity log, but the CNA does not disclose the rendering code or exact neutralization failure. Exploitation requires high-privileged access and a victim to view the stored content, enabling script execution in that victim's browser context.
