CVE-2019-15123Network attack vector

Authenticated code execution via ASPX logo upload

Published Jun 12, 2020 · Updated Aug 5, 2024

Unrestricted file upload in Viki Vera 4.9.1.26180 allows remote authenticated users to execute code through the Branding Module. The module accepts attacker-supplied ASPX content as a logo upload, allowing the web server to process executable content instead of restricting uploads to images. Access to the authenticated logo-change function is required; successful exploitation runs attacker-supplied code on the Vera site.
