Hacking MSSQL on Cloud. All of them. How I became sysadmin on Azure, AWS, GCP and Alibaba.

Fabiano Amorim

Can a standard user hijack your managed cloud database? See how abusing DDL triggers and un-sanitized T-SQL yielded full sysadmin rights across Azure, AWS, GCP, and Alibaba.

Identifying SQL injection vulnerabilities in internal stored procedures

Automating security checks reveals common flaws in complex internal queries where user input is unsafely concatenated.

#2 about 4 min

Validating SQL injection risks with a PowerShell module

A programmatic demonstration parses statements to pinpoint unsafe dynamic command concatenations and risks stemming from implicit data type conversions.

#3 about 5 min

Exploiting internal stored procedures to execute shell commands

System procedures inherently possess elevated privileges that attackers compromise to bypass execution restrictions and run operating system commands.

#4 about 3 min

Bypassing sysadmin restrictions across major cloud providers

Despite restrictive managed service guarantees, underlying architectural implementation flaws enable full privilege escalation across multiple cloud database environments.

#5 about 7 min

Exploiting managed instances on Azure and Alibaba Cloud

Bypassing weak internal mitigations and exploiting shared architectural environments exposes cross-tenant databases and plaintext system credentials.

#6 about 7 min

Hijacking administrative execution context using DDL event triggers

Malicious data definition triggers intercept automated administrative procedures to secretly elevate standard application users into elevated administrators.

#7 about 2 min

Hardening database environments through the principle of least privilege

Revoking default access to unneeded system capabilities proactively protects instances against chained privilege escalation attacks.
