Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match
prevent

Directly mitigates the CVE by requiring timely remediation and patching of the vulnerable News Event WordPress theme to versions beyond 1.0.1.

SI-10 Information Input Validation good match
prevent

Validates the content of file uploads to the WordPress theme, preventing acceptance of dangerous file types that could lead to remote code execution.

SI-9 Information Input Restrictions good match
prevent

Restricts file uploads in the News Event theme to only permitted types and characteristics, blocking unrestricted uploads of dangerous files by low-privilege users.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
attack.mitre.org →
T1100 Web Shell Persistence
A Web shell is a Web script that is placed on an openly accessible Web server to allow an adversary to use the Web server as a gateway into a network.
attack.mitre.org →
T1505.003 Web Shell Persistence
Adversaries may backdoor web servers with web shells to establish persistent access to systems.
attack.mitre.org →
Why these techniques?

Unrestricted arbitrary file upload (CWE-434) in a public-facing WordPress theme directly enables web shell deployment and remote code execution on the server.

Deeper analysisAI

CVE-2025-62056 is an Unrestricted Upload of File with Dangerous Type vulnerability (CWE-434) in the News Event WordPress theme developed by BlazeThemes. The issue affects the News Event theme from unknown initial versions through version 1.0.1.

The vulnerability has a CVSS v3.1 base score of 9.9 (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H), indicating it is exploitable over the network with low attack complexity by an authenticated user with low privileges and no user interaction required. Successful exploitation allows the attacker to achieve high impacts on confidentiality, integrity, and availability, likely enabling arbitrary file uploads that could lead to remote code execution or full server compromise due to the changed scope.

Mitigation details are available in advisories such as the Patchstack database entry at https://patchstack.com/database/Wordpress/Theme/news-event/vulnerability/wordpress-news-event-theme-1-0-1-arbitrary-file-upload-vulnerability?_s_id=cve.
