CWE-119Published: November 17, 2003· Updated: Jun 16, 2026
Official Description
ProFTPD 1.2.7 through 1.2.9rc2 does not properly translate newline characters when transferring files in ASCII mode, which allows remote attackers to execute arbitrary code via a buffer overflow using certain files.
Technical Analysis
CVE-2003-0831 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-2003-0831. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
