CQURE Hacks #74: Microsoft SQL Server Privilege Escalation
We’re diving into a classic but devastatingly effective exploit path. Many organizations leave their SQL Servers vulnerable through a combination of three simple misconfigurations: a database set to “trustworthy,” an owner with sysadmin rights (like SA), and a low-privilege user with db_owner permissions. By abusing these settings, an attacker can create a stored procedure that […]
CQURE Hacks #70: NTLM Relay Attacks in Practice: Exploiting Missing SMB Signing
In this episode, we start by verifying vulnerable configurations on SRV01 (10.10.10.20) and Windows 11 (10.10.10.40). Server and client SMB signing enforcement is false. Nmap confirms “enabled but not required,” and NetExec scans the network to list relay targets (/tmp/relay.txt). Responder (NetBIOS/LLMNR poisoner, SMB/HTTP disabled) listens on eth0. Impacket-ntlmrelayx (-i interactive, –target-file relay.txt) relays intercepted […]
