ProFTPD Server Compromised in Attack
The main distribution server of the ProFTPD Project was compromised in an attack, allowing a rogue version of the ProFTPD software to be uploaded and distributed for days.The main distribution server of the open-source ProFTPD Project was compromised in an attack that enabled whoever was behind it to upload and distribute a malicious version of ProFTPD software. The ProFTPD Project develops file transfer protocol (FTP) server software. According to the project team, the compromise occurred Nov. 28, and went undetected until Dec. 1. In addition to the main distribution server, all the mirror servers were affected as well, and any users running versions of ProFTPD that have been downloaded and compiled during the past few days should "check their systems for security compromises and install unmodified versions of ProFTPD," the team advised.
In a message to the project's mailing list on SourceForge, Project Maintainer TJ Saunders speculated the attacker or attackers used an unpatched security vulnerability in the FTP daemon to gain access to the server and then replaced the source files for ProFTPD 1.3.3c with a version containing a backdoor.
