CVE-2020-35734Public exploitNetwork attack vector

Authenticated remote code execution via unsanitized user fields

Published Feb 15, 2021 · Updated Aug 4, 2024

Code injection in Sruu.pl Batflat 1.3.6 allows remote authenticated users to execute arbitrary PHP code through the Users tab. The Users tab stores unsanitized attributes such as Displayed name, causing embedded PHP code to be evaluated by the web server. Access to the administration panel and Users tab is required, and successful execution runs with application privileges on an unsupported product.
