CVE-2025-9316 affects N-able N-central versions prior to 2025.4. The vulnerability allows the application to generate valid session IDs for unauthenticated users, resulting in an authentication bypass condition. Available supporting content consistently describes the issue as an unauthenticated session bypass or improper access control flaw in N-central. In practice, an attacker can interact with the exposed N-central web application and obtain a session identifier without first authenticating, which can then be used to access functionality that should require a logged-in session. Reporting also indicates this flaw can be chained with CVE-2025-11700, an XXE issue, to achieve unauthenticated local file read on affected N-central instances, including versions noted as earlier than 2025.4.0.9 in Metasploit-related references.

Repository contains a single Go source file implementing a Goby Goscanner exploit module for CVE-2025-11700 (N-able N-central XXE in SOAP services prior to 2025.4). Structure & purpose: - One file: `N_central _dms_services_ServerMMS_XML_External_Entity_Injection_Vulnerability_CVE-2025-11700.go`. - Registers an exploit definition (JSON metadata) with Goby’s scanner framework, including FOFA/Goby fingerprints, CVE, severity, and user parameters. Exploit flow (high level): - Performs a basic GET / check for reachability. - Core logic in `doExploit_4a2b9d(u, dtdUrl)`: - Step 1: Sends a SOAP `sessionHello` request to `/dms/services/ServerUI` to obtain a SessionID (used to proceed with subsequent SOAP interactions). - Subsequent steps (partially truncated in provided content) upload/submit an XML payload that references an attacker-controlled external entity/DTD URL and then triggers parsing on `/dms/services/ServerMMS`, causing either: - Out-of-band interaction to the provided OOB URL/domain (DNS/HTTP), or - Error-based leakage where file contents (e.g., `/etc/passwd`) appear in the SOAP fault response. Capabilities: - Unauthenticated network exploitation against exposed N-central SOAP endpoints. - XXE-based information disclosure (arbitrary file read) and OOB verification. - Two operating modes: - Scan mode: auto-generates an OOB URL via Goby GodClient and confirms via `PullExists`. - Exploit mode: uses user-supplied `attack_url` (DNSLog or hosted DTD) and reports either leaked content (e.g., detects `root:`) or instructs to check OOB server. Notable implementation details: - TLS verification is disabled for the SOAP POST in step 1 (`VerifyTls = false`), easing exploitation against self-signed deployments. - Provides a recommended error-based DTD snippet to coerce file content into an error path for direct response retrieval.
This repository contains a proof-of-concept exploit for unauthenticated XXE (XML External Entity) vulnerabilities in N-able N-central, chaining CVE-2025-9316 and CVE-2025-11700 to read arbitrary files from the target server. The exploit is implemented in a single Python script ('ncentral_xxe_file_read.py') and is accompanied by a README.md with usage instructions and background information. The script works by: 1. Starting a local HTTP server (DTD server) to serve a malicious DTD file. 2. Sending a crafted SOAP request to the target N-central instance to obtain a session ID. 3. Triggering the XXE vulnerability by sending a specially crafted XML payload that references the attacker's DTD server. 4. Causing the target to read a specified file (default: /etc/passwd) and exfiltrate its contents to the attacker. The script allows the attacker to specify the target URL, the file to read, and the IP/port for the DTD server. It also includes a test mode to check endpoint accessibility. The main attack vector is network-based, targeting the SOAP endpoints '/dms/services/ServerUI' and '/dms/services/ServerMMS' on the N-central server. The exploit is a functional proof-of-concept and does not include weaponized features such as automated credential extraction or post-exploitation modules.
