Unrestricted File Upload in Dell KACE K1000 download_agent.php

IdentifiersCVE-2014-125113CWE-434· Unrestricted Upload of File with…

CVE-2014-125113 is an unrestricted file upload vulnerability in Dell (formerly Quest) KACE K1000 System Management Appliance affecting version 5.0 through 5.3, 5.4 before 5.4.76849, and 5.5 before 5.5.90547. The flaw is present in the download_agent.php endpoint, which allows an attacker to upload arbitrary PHP files into a temporary directory that is web-accessible. Those uploaded files can subsequently be executed when backend code includes files from attacker-controlled paths. In practical terms, the issue is not limited to arbitrary file placement; it can lead to execution of attacker-supplied PHP code on the appliance.

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 can result in remote code execution in the context of the web application on the KACE K1000 appliance. An attacker can place arbitrary PHP payloads on the system and have them executed via backend file inclusion behavior, enabling full compromise of the application layer and potentially the underlying appliance, including unauthorized access to managed system data, administrative functions, and further post-exploitation activity.

Mitigation

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

If immediate patching is not possible, restrict network access to the KACE K1000 management interface and specifically limit exposure of the vulnerable web application endpoints to trusted administrative networks only. Apply compensating controls such as reverse-proxy or WAF rules to block unauthorized access to upload-related requests targeting download_agent.php, and monitor the appliance for unexpected PHP files in temporary or web-accessible directories. Review logs and file integrity for evidence of malicious uploads or execution. These measures are temporary and do not replace upgrading to a fixed version.

Remediation

Patch, then assume compromise.

Upgrade Dell KACE K1000 System Management Appliance to a fixed release. Affected versions are 5.0 through 5.3, 5.4 prior to 5.4.76849, and 5.5 prior to 5.5.90547; remediation therefore requires updating to 5.4.76849 or later in the 5.4 branch, 5.5.90547 or later in the 5.5 branch, or a newer supported release. Because the vulnerability permits arbitrary PHP upload and execution, organizations should treat exposed vulnerable systems as potentially compromised and perform appropriate incident response validation after patching.

dell_kace_k1000_upload.rbMaturityWeaponizedFrameworkmetasploitVerified exploit

This repository contains a single Metasploit module (modules/exploits/unix/http/dell_kace_k1000_upload.rb) targeting a file upload vulnerability in Dell KACE K1000 appliances (versions 5.0 to 5.3, 5.4 prior to 5.4.76849, and 5.5 prior to 5.5.90547). The exploit allows unauthenticated attackers to upload a PHP payload via the /service/kbot_upload.php endpoint, which is then executed to achieve remote code execution as the 'www' user. The module further abuses the KSudoClient::RunCommandWait function to escalate privileges to root. The exploit is operational, providing arbitrary command execution and privilege escalation. The code is written in Ruby and is structured as a standard Metasploit module, with clear separation of check and exploit routines. The main fingerprintable endpoints are the vulnerable upload handler and the temporary PHP file location used for payload execution.
