CVE-2024-21493

Estado: AnalizadaMedia (5.3)—

All versions of the package github.com/greenpau/caddy-security are vulnerable to Improper Validation of Array Index when parsing a Caddyfile. Multiple parsing functions in the affected library do not validate whether their input values are nil before attempting to access elements, which can lead to a panic (index out of range). Panics during the parsing of a configuration file may introduce ambiguity and vulnerabilities, hindering the correct interpretation and configuration of the web server.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
