Description

Badaso CMS file upload vulnerability

An arbitrary code execution vulnerability in Badaso CMS 2.9.11. The Media Manager allows authenticated users to upload files containing embedded PHP code via the file-upload endpoint, bypassing content-type validation. When such a file is accessed via its URL, the server executes the PHP payload, enabling an attacker to run arbitrary system commands and achieve full compromise of the underlying host. This has been demonstrated by embedding a backdoor within a PDF and renaming it with a .php extension.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.
