Microsoft SharePoint 2019 NTLM Authentication: A Comedy of Security Errors
Microsoft SharePoint 2019’s NTLM authentication is like leaving your front door wide open. Low-privileged accounts can waltz in, rummage through your SharePoint secrets, and even map out your internal structure. With NTLM over HTTP, hackers get a one-way ticket to your metadata!
Hot Take:
Ah, Microsoft SharePoint 2019, proving once again that when it comes to NTLM authentication, it’s like leaving the front door wide open with a welcome mat that says “Hackers Welcome!” Who needs encryption or fine-grained access control when you can just let attackers waltz in and help themselves to a buffet of rich metadata? It’s like a piñata of vulnerabilities just waiting to be whacked open!
Key Points:
- SharePoint 2019 exposes NTLM-authenticated endpoints to unauthorized users.
- Vulnerability allows attackers to access sensitive metadata about SharePoint sites.
- NTLM over HTTP lacks encryption, making it easy prey for cyber baddies.
- Lack of access control on `_api/web` endpoint is a big security faux pas.
- Error codes in NTLM act as a map for hackers, leading them straight to treasure.
