Uncontrolled Search Path Element in Advantech WebAccess < V8.2_20170817

IdentifiersCVE-2017-12717CWE-427· Uncontrolled Search Path Element

Advantech WebAccess versions prior to V8.2_20170817 are vulnerable to an Uncontrolled Search Path Element (CWE-427) issue. The application loads DLLs without specifying a full path, allowing an attacker to place a malicious DLL in a directory that is searched before the legitimate one. When the application loads the DLL, the attacker's code is executed in the context of the application.

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.

Successful exploitation allows arbitrary code execution with the privileges of the application, potentially leading to full system compromise if the application runs with elevated privileges.

Mitigation

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

As an interim measure, restrict write permissions to directories in the DLL search path to trusted users only, and monitor for unauthorized files in those directories. Ensure that only trusted directories are included in the search path and use application whitelisting where possible.

Remediation

Patch, then assume compromise.

Upgrade Advantech WebAccess to version V8.2_20170817 or later, which addresses the uncontrolled search path element issue.

POC-CVE-2017-12615-or-CVE-2017-12717MaturityOperationalVerified exploit

This repository contains a Python proof-of-concept exploit for CVE-2017-12615 and CVE-2017-12617, targeting Apache Tomcat servers (primarily on Windows) with the HTTP PUT method enabled. The main file, 'tomcate-cve-put.py', attempts to upload a JSP webshell to the target server by sending a PUT request. If successful, the attacker can access the uploaded JSP file via HTTP and execute arbitrary system commands through a web interface. The exploit requires the attacker to specify the target host and the desired JSP filename. The repository is structured simply, with a README, a .gitignore, and the exploit script. The exploit is operational, as it provides a working payload (JSP webshell) and automates the attack process.
