PoC for Silverpeas <= 6.4.2 Username Enumeration

介绍

# CVE-2025-46047
## Silverpeas <= 6.4.2 Username Enumeration PoC
Proof-of-Concept script for demonstrating a username enumeration vulnerability in Silverpeas versions 6.4.1 and 6.4.2.

## Vulnerability Details

* **Affected Software:** Silverpeas
* **Affected Versions:** 6.4.1, 6.4.2 (and potentially earlier versions)
* **Fixed Version:** 6.4.3
* **Vulnerability Type:** Username Enumeration via Observable Response Discrepancy (CWE-204)
* **Vendor Tracking ID:** Silverpeas Bug #14829

**Summary:** The vulnerability exists in the forgot password functionality (`/silverpeas/CredentialsServlet/ForgotPassword` endpoint). By sending POST requests with potential usernames in the `Login` parameter, the server responds with different HTTP status codes (200 OK for valid users, 302 Found for invalid users). This discrepancy allows a remote, unauthenticated attacker to determine valid usernames on the system.

## Proof-of-Concept (PoC) Script

* **Script Name:** `silverpeas_enum_poc.py`
* **Description:** This Python script automates the process of sending requests to the vulnerable endpoint with usernames (provided individually or from a wordlist) and identifies potentially valid/invalid accounts based on the server's HTTP status code response.

## Usage

### Requirements

* Python 3.x
* `requests` library (`pip install requests`)

### Instructions

1.  Clone the repository or download the script (`silverpeas_enum_poc.py`).
2.  Install dependencies: `pip install requests`
3.  Run the script from your terminal:

    * **Test a single username:**
        ```bash
        python silverpeas_enum_poc.py <TARGET_URL> -u <USERNAME>
        ```
        *Example:* `python silverpeas_enum_poc.py http://vulnerable-silverpeas.local -u admin`

    * **Test usernames from a file:**
        ```bash
        python silverpeas_enum_poc.py <TARGET_URL> -w <WORDLIST_FILE>
        ```
        *Example:* `python silverpeas_enum_poc.py https://vulnerable-silverpeas.com -w users.txt`

### Output

The script will output:
* `[+] Username '...' appears VALID (Status: 200)` for usernames likely corresponding to existing accounts.
* `[-] Username '...' appears INVALID (Status: 302)` for usernames likely not corresponding to existing accounts.
