    ## Description:
    Microsoft SharePoint Central Administration improperly exposes
    NTLM-authenticated endpoints to low-privileged or even brute-forced domain
    accounts. Once authenticated, an attacker can access the `_api/web`
    endpoint, disclosing rich metadata about the SharePoint site, including
    user group relationships, workflow configurations, and file system
    structures. The vulnerability enables username and password enumeration,
    internal structure mapping, and API abuse.
    
    Key issues include:
    - NTLM over HTTP (unencrypted)
    - No fine-grained access control on `_api/web`
    - NTLM error codes act as oracles for credential validation
