EasyImages 2.0 Arbitrary File Rename Vulnerability Allows Code Execution

CVE advisorySeverity: CRITICAL (CVSS 9.1)

CVE-2025-65473

EasyImages is a web application typically deployed to host and manage images, often acting as a public-facing service. Because the vulnerable component is part of the administrative interface of a web-based platform, it is commonly accessible over the network in environments where such web applications are hosted, making it a likely target for internet-reachable deployment patterns.

Horizon Alert

Summary of the vulnerability and why it matters

An arbitrary file rename vulnerability has been identified in a component of EasyImages 2.0, which could allow authenticated administrators to execute arbitrary code by manipulating uploaded file names. The main concern is confirming relevance and exposure to this specific technology.

File rename flaw allows code execution.
Critical vulnerability impacts image management.
Verify exposure and manage administrative access.

Attack Path

How an attacker could exploit the issue

An attacker with administrator privileges could target the `/admin/filer.php` component to rename an uploaded file with a specially crafted name. This crafted name would contain a malicious payload, which the vulnerable component would then execute.

Administrator access is required.
Uploading a file with a crafted name triggers it.
Arbitrary code execution is possible.

Live Threat

Current exploitation, exposure, and threat context

An arbitrary file rename vulnerability in the EasyImages /admin/filer.php component could allow an administrator to execute arbitrary code by injecting a crafted payload into an uploaded file name. This could impact the confidentiality, integrity, and availability of the affected system.

Frequently asked questions

What is EasyImages 2.0?

EasyImages 2.0 is a web-based application designed to help users host, organize, and manage image files. It provides administrative tools to handle these media assets, which often serve as a backend utility for websites or online platforms that require efficient image storage and retrieval capabilities.

What does CWE-73 mean for CVE-2025-65473?

CWE-73 refers to Improper Limitation of a Pathname to a Restricted Directory. In this vulnerability, the software fails to properly sanitize input when renaming files. This allows an attacker to manipulate file paths, ultimately enabling them to execute malicious code on the host system.

How is the arbitrary file rename vulnerability triggered?

An attacker triggers this bug by submitting a specially crafted file name during a rename operation within the /admin/filer.php component. Note that standard file uploads without this specific manipulation do not trigger the flaw; successful exploitation requires the actor to inject malicious payload syntax into the rename request.

Why should I care about this vulnerability?

According to Halo Surface Signal, EasyImages is often deployed as a public-facing service, meaning its administrative interface may be reachable over the internet. Because the vulnerability allows for remote code execution, any instance accessible from outside your private network faces a higher risk of compromise by unauthorized actors.

How do I respond to CVE-2025-65473?

Your first step is to locate all deployments of EasyImages 2.0 within your environment. Once identified, evaluate their network reachability and determine who is responsible for the platform. Coordinate with the relevant owners to assess the risk and initiate the update process for affected systems.
