Overview<\/strong><\/p>\n

The vulnerability, identified as CVE-2025-27022, is a significant path traversal vulnerability that affects the WebGUI HTTP endpoint in Infinera G42 version R6.1.3. This vulnerability is significant as it allows remote authenticated users to potentially download all OS files via HTTP requests, highlighting a potential risk of system compromise and data leakage.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Infinera G42 | R6.1.3<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The exploit leverages a path traversal vulnerability in the WebGUI HTTP endpoint. This vulnerability stems from a lack of sufficient validation of user-supplied input. The flaw allows authenticated users to access all files on the target machine file system that are readable to the user account used to run the httpd service. This means that a malicious authenticated user could potentially download all readable files on the system via HTTP requests.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

The vulnerability might be exploited using a crafted HTTP request like the one below:<\/p>\n

GET \/..\/..\/..\/etc\/passwd HTTP\/1.1\nHost: target.example.com\nAuthorization: Basic [Base64-encoded-credentials]<\/code><\/pre>\n
In this example, the “GET” request attempts to traverse the file system to reach the “\/etc\/passwd” file, a common target for attacks due to its sensitive content. The “Authorization” header includes Base64-encoded credentials for an authenticated user.<\/p>\n","protected":false},"excerpt":{"rendered":"
