Nozomi Networks Labs identified a CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the file management functionality of the XML-RPC management interface of KUNBUS RevPiPyLoad in version 0.11.0 that allows a local unauthenticated attacker to read arbitrary files with the privileges of the RevPiPyLoad daemon, including sensitive configuration and credential material, by sending crafted requests to the local management service.

Klassifikation & Betroffenheit:

CWE-22 Kunbus RevPiPyLoad 0 ≤0.11.0

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') 🎯 High

The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.

🛡️ Empfohlene Mitigation: Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does. When performing input validation, consider all …

Datenquellen & Methodik: Primärquelle ist die EUVD der ENISA (laufender Datenbank-Sync, alle 15 Minuten), abgeglichen mit dem CISA-KEV-Katalog und der NVD — Detail-Dossiers reichern fehlende Felder live per NVD an — mit Fallback auf CIRCL vulnerability-lookup (EU/Non-Profit, aggregiert CVE-, GitHub- und OSV-Advisories). Der CISA-KEV-Katalog (Known Exploited Vulnerabilities, ~1.700 aktiv ausgenutzte Schwachstellen) wird bei jedem Sync vollständig neu geladen und kreuzreferenziert — filterbar über die KEV-Pille. CVSS 3.1 wird nach Ampel-Logik aus Verteidigersicht dekodiert; EPSS bezeichnet die 30-Tage-Exploit-Wahrscheinlichkeit (FIRST.org).
