CVE-2015-1834 CC Path Traversal vulnerability


James Bayer
 

Severity: Medium

Vendor: Cloud Foundry Foundation

Vulnerable Versions: Cloud Foundry Runtime Releases prior to 208

CVE References: CVE-2015-1834
Description:

A path traversal vulnerability was identified in the Cloud Foundry
component Cloud Controller. 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.

Affected Products and Versions:

Cloud Foundry Runtime cf-release versions v207 or earlier are susceptible
to the vulnerability

Mitigation:

The Cloud Foundry project recommends that Cloud Foundry Runtime Deployments
running Release v207 or earlier upgrade to v208 or later.
