NVD-CWE-OtherPublished: January 9, 2001· Updated: Jun 16, 2026

3.7
CVSS v3.1

Official Description

crontab by Paul Vixie uses predictable file names for a temporary file and does not properly ensure that the file is owned by the user executing the crontab -e command, which allows local users with write access to the crontab spool directory to execute arbitrary commands by creating world-writeable temporary files and modifying them while the victim is editing the file.

Technical Analysis

CVE-2000-1096 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.

A proof-of-concept (PoC) exploit exists for CVE-2000-1096. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
