Unauthenticated Arbitrary File Upload in EGallery 1.2

IdentifiersCVE-2012-10052CWE-434· Unrestricted Upload of File with…

EGallery 1.2 contains an unauthenticated arbitrary file upload vulnerability in uploadify.php. The application does not validate uploaded file types or enforce authentication, allowing an attacker to upload malicious PHP files to a web-accessible EGallery directory and execute them in the web-server context.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

An unauthenticated remote attacker can achieve full remote code execution with the privileges of the web server.

Mitigation

If you can’t patch tonight, do this now.

As an immediate mitigation, restrict or disable access to uploadify.php, require authentication before any upload action, and configure the web server to disallow execution of PHP or other server-side scripts in upload directories. Apply WAF or reverse-proxy rules to block direct access to the vulnerable upload endpoint and suspicious multipart upload requests. Monitor the web-accessible egallery/ directory for newly created files, especially .php or other executable content, and inspect logs for anomalous requests to uploaded files.

Remediation

Patch, then assume compromise.

Upgrade to a fixed version if one is available from the vendor. If source modification is required, remediate by enforcing authentication on the upload endpoint, strictly validating uploaded file types using an allowlist, verifying content rather than relying only on file extensions, preventing upload of server-executable files such as PHP, and storing uploaded content outside the web root or in a location where script execution is disabled. Review the egallery/ directory for previously uploaded malicious files and remove any unauthorized content.

egallery_upload_exec.rbMaturityWeaponizedFrameworkmetasploitVerified exploit

This repository contains a single Metasploit module (egallery_upload_exec.rb) that exploits an unauthenticated file upload vulnerability in EGallery 1.2 (CVE-2012-10052). The exploit abuses the uploadify.php script to upload a malicious PHP payload to the egallery/ directory. Once uploaded, the payload is executed by sending an HTTP GET request to the uploaded file, resulting in remote code execution. The module is written in Ruby and leverages Metasploit's HttpClient mixin. The only required configuration is the TARGETURI option, which specifies the base path to the EGallery installation. The exploit is operational and provides the attacker with the ability to execute arbitrary PHP code on the target server. The main fingerprintable endpoints are /egallery/uploadify.php (for upload) and the resulting /egallery/<payload>.php (for execution).
