Summary
axios versions 0.31.0 before 0.33.0 and 1.15.0 before 1.18.0 fail to recognize 0.0.0.0 as a loopback address in shouldBypassProxy.js, allowing requests to 0.0.0.0 to bypass NO_PROXY rules. Attackers can supply 0.0.0.0 URLs to route requests through configured proxies, potentially exposing local services when the proxy can reach the destination.
A flaw was found in axios. This vulnerability occurs because the software fails to correctly identify 0.0.0.0 as a local loopback address when evaluating NO_PROXY rules.
A remote attacker could exploit this by providing a 0.0.0.0 URL, causing requests to bypass intended proxy restrictions. This could lead to the exposure of internal services to the configured proxy, potentially allowing unauthorized access to local resources.
Red Hat severity: Moderate — CVSS 5.8 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N). Weakness: CWE-115.
