Misconfigurations in web applications, particularly enabled directory listings, can lead to severe data exposure and breaches. CloudSEK’s BeVigil identified critical vulnerabilities exposing sensitive data, emphasizing the need for immediate corrective actions. Affected: BeVigil, web applications
Keypoints :
- Misconfigurations in web applications can have disastrous consequences.
- CloudSEK’s BeVigil discovered a critical vulnerability due to enabled directory listings.
- Directory listings can expose sensitive data like access tokens, PII, and database logs.
- Multiple vulnerable URLs were identified, allowing ongoing access to sensitive data.
- Exposed data includes authentication tokens, PII, audit logs, and database backups.
- Recommendations include disabling directory listings and enhancing monitoring practices.
- Regular security audits and robust authentication protocols are essential for protection.
- BeVigil helps organizations detect vulnerabilities early to mitigate risks.
MITRE Techniques :
- TA0001 – Initial Access: Exploiting misconfigurations to gain unauthorized access to sensitive data.
- TA0002 – Execution: Utilizing exposed data to conduct further malicious actions.
- TA0003 – Persistence: Maintaining access through ongoing exposure of sensitive directories.
- TA0004 – Privilege Escalation: Leveraging exposed admin logs to replicate legitimate activities.
- TA0005 – Credential Access: Accessing authentication tokens and PII for identity theft.
Indicator of Compromise :
- [domain] example.com
- [url] example.com/vulnerable-directory/
- [file name] access_logs.txt
- [file name] admin_activity_logs.txt
- [file name] database_backup.sql
