How a Single SQL Injection Exposed 45 Databases, 240 S3 Buckets and Entire Cloud Infrastructure

A recent vulnerability identified by CloudSEK’s BeVigil revealed an unauthenticated API endpoint on a recruitment service provider vulnerable to SQL Injection, potentially leading to Remote Code Execution and unauthorized access to sensitive data. Immediate mitigation actions are advised to prevent exploitation. Affected: API endpoints, cloud infrastructure, recruitment service provider

Keypoints :

  • CloudSEK’s BeVigil discovered an unauthenticated API endpoint vulnerable to SQL Injection.
  • This vulnerability could lead to Remote Code Execution and unauthorized data access.
  • Attackers could extract data from 45 databases and 9000+ tables.
  • Over 240 S3 Buckets containing sensitive data were at risk.
  • Potential for attackers to escalate privileges and execute remote commands on the cloud infrastructure.
  • Exposure of critical data could result in privacy violations and financial risks.
  • Mitigation steps recommended include securing API endpoints, using parameterized queries, and conducting regular security audits.

MITRE Techniques :

  • SQL Injection (T1203) – Attackers exploit a vulnerable API endpoint to execute arbitrary SQL queries.
  • Remote Code Execution (T1203) – Exploit SQL Injection to gain remote access and execute commands on the cloud environment.

Indicator of Compromise :

  • [URL] https://example.com – Vulnerable API endpoint for exploitation.
  • [Hash] 3a1d0b8ad61a3e69f4b15d6234b24b78 – Example of a potential exposed hash (not given in text, for illustration purposes only).
