CVE-2024-21493

MEDIUM

caddy-security - Denial of Service via Caddyfile Array Index Parsing

Title source: llm
STIX 2.1

Description

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.
