A path traversal vulnerability was identified in the Cloud Foundry component Cloud Controller that affects cf-release versions prior to v208

A path traversal vulnerability was identified in the Cloud Foundry component Cloud Controller that affects cf-release versions prior to v208 and Pivotal Cloud Foundry Elastic Runtime versions prior to 1.4.2. Path traversal is the 'outbreak' of a given directory structure through relative file paths in the user input. It aims at accessing files and directories that are stored outside the web root folder, for disallowed reading or even executing arbitrary system commands. An attacker could use a certain parameter of the file path for instance to inject '../' sequences in order to navigate through the file system. In this particular case a remote authenticated attacker can exploit the identified vulnerability in order to upload arbitrary files to the server running a Cloud Controller instance - outside the isolated application container.

Remediation

Which version to upgrade to

Fix versions compiled from the vendor, package registries and Microsoft. Verify the vendor's note before upgrading.

No fix version is recorded for this entry. Check the references for vendor advisories.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

Weakness class (CWE)

CWE-22 · Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVSS vector

CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N

nvd-primary

Root cause

A user-supplied file name is joined with the allowed directory, but the result is never checked to confirm it is still inside that directory.

The bug in code

The whole CWE-22 class

A representative example of this vulnerability class. Not the vendor's source code; it shows the faulty pattern and its fix.

Vulnerable

ts
const file = path.join(ROOT, req.query.name);res.sendFile(file);

Fixed

ts
const file = path.resolve(ROOT, req.query.name);if (!file.startsWith(ROOT + path.sep)) {  return res.sendStatus(400);}res.sendFile(file);
