CWE-264Published: January 28, 2011· Updated: Jun 16, 2026
6.9
CVSS v3.1
Official 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.
Technical Analysis
CVE-2011-0343 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
