CVE-2011-1548
CWE-264Published: March 30, 2011· Updated: Jun 16, 2026
6.3
CVSS v3.1
Official Description
The default configuration of logrotate on Debian GNU/Linux uses root privileges to process files in directories that permit non-root write access, which allows local users to conduct symlink and hard link attacks by leveraging logrotate's lack of support for untrusted directories, as demonstrated by /var/log/postgresql/.
Technical Analysis
CVE-2011-1548 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.
