Challenge

CloudSEK’s Attack Surface Monitoring platform, BeVigil, identified ASP.NET documentation exposure on one of the web applications.

An API endpoint was particularly vulnerable to SQL injection, a critical vulnerability allowing complete database access to a threat actor.

The web application was identified as part of the trading platform’s SAP system, with the exposed API endpoint acting as a wrapper to the SAP backend, potentially leading to a large-scale data breach.

‍

Impact

The public exposure of the SAP database can result in significant security risks, including unauthorized access to sensitive data such as organization names, financial data, phone numbers, and addresses.

Attackers could exploit this vulnerability to gain deeper system access, leading to service downtime, privilege escalation, and exposure of proprietary information.

Additionally, compromised systems could be misused for malicious activities, causing further damage to the platform's reputation and customer trust.

Solution

CloudSEK BeVigil promptly identified and secured the exposed API endpoint, ensuring that sensitive data was protected and access was restricted.

‍

Implementation:

Detection:‍

  • CloudSEK BeVigil discovered the vulnerable API endpoint exposing the SAP database.

‍

Threat Analysis:

  • The SQL injection vulnerability could allow threat actors to gain unauthorized access to internal systems, potentially exposing sensitive financial data and personal information
  • The analysis revealed that attackers could exploit this vulnerability to conduct targeted attacks, privilege escalation, and unauthorized data access.

‍

Immediate Actions:

  • Secured the vulnerable API endpoint to prevent further unauthorized access.
  • Implemented input validation and parameterized queries to mitigate the risk of SQL injection.
  • Disabled the ASP.NET documentation to prevent exposure of sensitive configuration details.

‍

Preventive Measures:

  • Conducted regular security audits and penetration testing to ensure ongoing protection.
  • Implemented multi-factor authentication (MFA) and secure storage solutions for sensitive data.
