Technical ContextAI · show details

This vulnerability (CWE-538: Insertion of Sensitive Information into Externally-Accessible File) affects Astpp. ASTPP 4.0.1 contains an information disclosure vulnerability that allows unauthenticated attackers to download database backup files by predicting backup filename patterns. Attackers can generate a list of 6-digit PIN combinations and fuzz the backup download URL to exfiltrate sensitive database information from the /database_backup/ directory.

HIGH 7.5

DescriptionCVE.org

ASTPP 4.0.1 contains an information disclosure vulnerability that allows unauthenticated attackers to download database backup files by predicting backup filename patterns. Attackers can generate a list of 6-digit PIN combinations and fuzz the backup download URL to exfiltrate sensitive database information from the /database_backup/ directory.

Executive ViewAI

Why It Matters

Astpp versions up to 4.0.1 contain a vulnerability that exposes sensitive information in publicly accessible files, potentially compromising customer data, credentials, or configuration details. Organizations running affected versions face immediate risk of data breach and regulatory compliance violations until remediation is completed.

Business Impact: High

Compensating Controls

Implement Web Application Firewall (WAF) rules to block external access to sensitive file paths; apply network segmentation to restrict Astpp system accessibility to authorized networks only; disable or restrict features that write sensitive data to web-accessible directories; enforce strict file permissions and remove world-readable access on configuration and data files; implement continuous file integrity monitoring on Astpp directories; enable authentication/IP whitelisting at reverse proxy level if applicable.
