CVE-2025-52353
CWE-434Published: August 26, 2025· Updated: Jun 17, 2026
Official Description
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.
Risk Analysis
Badaso CMS 2.9.11 is vulnerable to arbitrary code execution because the Media Manager fails to properly validate file uploads. An attacker can upload and execute malicious PHP scripts, leading to full system compromise. The critical CVSS score highlights the potential for total host takeover.
No public exploit is currently known, and the vulnerability is not in KEV. It is remotely exploitable with low attack complexity.
Upgrade to a version of Badaso CMS that implements strict content-type validation for file uploads. Ensure that the web server is configured to prevent the execution of scripts in upload directories.
Technical Analysis
CVE-2025-52353 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
