Overview

CVE-2006-5229 is a low-severity vulnerability affecting openbsd openssh. It was published on October 10, 2006 and has a CVSS 2.0 base score of 2.6 (LOW).

This vulnerability has a CVSS 2.0 base score of 2.6, rated LOW. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

OpenSSH portable 4.1 on SUSE Linux, and possibly other platforms and versions, and possibly under limited configurations, allows remote attackers to determine valid usernames via timing discrepancies in which responses take longer for valid usernames than invalid ones, as demonstrated by sshtime. NOTE: as of 20061014, it appears that this issue is dependent on the use of manually-set passwords that causes delays when processing /etc/shadow due to an increased number of rounds.

Remediation

Check the references section for vendor advisories and patches from openbsd. Update openssh 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.
