6.9 · MEDIUMOverview
CVE-2011-0343 is a medium-severity vulnerability affecting oneidentity syslog-ng. It was published on January 28, 2011 and has a CVSS 2.0 base score of 6.9 (MEDIUM).
This vulnerability has a CVSS 2.0 base score of 6.9, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
Balabit syslog-ng 2.0, 3.0, 3.1, 3.2 OSE and PE, when running on FreeBSD or HP-UX, does not properly perform cast operations, which causes syslog-ng to use a default value of -1 to create log files with insecure permissions (07777), which allows local users to read and write to these log files.
Remediation
Check the references section for vendor advisories and patches from oneidentity. Update syslog-ng 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.
