SMBLoris Denial Of Service

There's a lot of talk about SMBLoris but nobody seems to have written a public efficient PoC yet, so I gave it a shot. A single instance takes down a fully patched Windows 10 Pro box with 8GiB of RAM in less than 10 seconds. I tried using Scapy initially, but it's dog slow, so I went with C. The...

Samba 4.5.2 - Symlink Race Permits Opening Files Outside Share Directory Vulnerability

Exploit for multiple platform in category remote exploits Source: https://bugs.chromium.org/p/project-zero/issues/detail?id=1039 The Samba server is supposed to only grant access to configured share directories unless "wide links" are enabled, in which case the server is allowed to follow symlink...

The vulnerability of Samba software allows a malicious individual to compromise the accessibility of protected information.

The vulnerability in the pushascii function of Samba’s smbd allows remote users who have completed authentication to trigger a service failure—a memory-related error and an unexpected termination of the daemon—by attempting to read the path name in Unicode format without using Unicode. This leads...
