Overview

CVE-2008-4677 is a medium-severity vulnerability affecting vim vim. It was published on October 22, 2008 and has a CVSS 2.0 base score of 4.3 (MEDIUM).

This vulnerability has a CVSS 2.0 base score of 4.3, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

autoload/netrw.vim (aka the Netrw Plugin) 109, 131, and other versions before 133k for Vim 7.1.266, other 7.1 versions, and 7.2 stores credentials for an FTP session, and sends those credentials when attempting to establish subsequent FTP sessions to servers on different hosts, which allows remote FTP servers to obtain sensitive information in opportunistic circumstances by logging usernames and passwords. NOTE: the upstream vendor disputes a vector involving different ports on the same host, stating "I'm assuming that they're using the same id and password on that unchanged hostname, deliberately."

Remediation

Check the references section for vendor advisories and patches from vim. Update vim to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
