CVE-2000-0844
CWE-264Published: November 14, 2000· Updated: Jun 16, 2026
10.0
CVSS v3.1
Official Description
Some functions that implement the locale subsystem on Unix do not properly cleanse user-injected format strings, which allows local attackers to execute arbitrary commands via functions such as gettext and catopen.
Technical Analysis
CVE-2000-0844 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
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-2000-0844. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
