Path Traversal in Mitel MiCollab NuPoint Unified Messaging

IdentifiersCVE-2024-41713CWE-22· Improper Limitation of a Pathname…

CVE-2024-41713 is a path traversal vulnerability in the NuPoint Unified Messaging (NPM) component of Mitel MiCollab through 9.8 SP1 FP2 (9.8.1.201). The issue is caused by insufficient input validation of attacker-controlled input, allowing an unauthenticated remote attacker to traverse paths outside the intended directory scope. According to the provided vendor advisory and description, successful exploitation can result in unauthorized access to provisioning information and other sensitive data, and may also enable unauthorized administrative actions. The vulnerability affects confidentiality, integrity, and availability by permitting access to, and potential corruption or deletion of, user data and system configuration information.

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 an unauthenticated attacker to access sensitive provisioning information, view user data and system configuration data, and potentially corrupt or delete users' data and system configurations. The Mitel advisory further indicates that exploitation can enable unauthorized administrative actions. Overall impact includes loss of confidentiality through unauthorized disclosure, loss of integrity through modification or corruption of data/configuration, and loss of availability through deletion or disruption of system configuration and user data.

Mitigation

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

Primary mitigation is to upgrade to MiCollab 9.8 SP2 (9.8.2.12) or later, or apply the Mitel patch for supported releases if upgrade must be deferred. As a compensating control, reduce exposure of MiCollab/NPM services to untrusted networks, restrict access to management and messaging interfaces to trusted IP ranges or VPN-only access where operationally feasible, and monitor for suspicious requests indicative of path traversal attempts against the NPM component. However, vendor patching/upgrading is the authoritative mitigation.

Remediation

Patch, then assume compromise.

Apply the vendor-provided fix by upgrading Mitel MiCollab to 9.8 SP2 (9.8.2.12) or later. Where supported and if immediate upgrade is not possible, apply the Mitel-provided patch for releases 6.0 and above in accordance with the referenced KMS article and vendor advisory instructions.

CVE-2024-41713-PoC-exploitMaturityPoCVerified exploit

This repository provides a proof-of-concept (PoC) exploit for CVE-2024-41713, a directory traversal and arbitrary file read vulnerability in Mitel MiCollab. The main exploit is implemented as a Bash script (cve-2024-41713-exploit.sh) that sends a crafted HTTP POST request to a vulnerable endpoint on the target MiCollab server. The request abuses path traversal in the endpoint to read the /etc/passwd file. The script then parses the response to extract and display the list of user accounts. The repository contains two files: a README.md with usage instructions and sample output, and the exploit script itself. The exploit is network-based, requires the attacker to specify the target's address, and demonstrates the ability to read arbitrary files from the server. No payload customization or advanced post-exploitation is present, making this a typical PoC exploit.

Mitel-MiCollab-Auth-Bypass_CVE-2024-41713MaturityPoCVerified exploit

This repository contains a Python exploit script and a README for CVE-2024-41713, targeting Mitel MiCollab (version 9.8 SP1 FP2 and earlier). The exploit leverages an authentication bypass and path traversal vulnerability to read arbitrary files from the target server. The script takes two arguments: the target URL and the file path to read. It first verifies the target is a Mitel MiCollab instance, then checks for vulnerability, and finally sends a crafted POST request to the '/npm-pwg/..;/ReconcileWizard/reconcilewizard/sc/IDACall' endpoint with a specially crafted XML payload to retrieve the specified file. The README provides usage instructions and affected version details. The exploit is operational and provides direct file read capability if the target is vulnerable.
