CVE-2011-1784
Status: ModifiedLow (3.6)—
The pidfile_write function in core/pidfile.c in keepalived 1.2.2 and earlier uses 0666 permissions for the (1) keepalived.pid, (2) checkers.pid, and (3) vrrp.pid files in /var/run/, which allows local users to kill arbitrary processes by writing a PID to one of these files.
CVSS
- Version: 2.0
- Vector: AV:L/AC:L/Au:N/C:N/I:P/A:P
- Base score: 3.6
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 0.37%
- Percentile among all scored CVEs: 28
- Score date: 10/3/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
