The main source-code repository for the Free Software Foundation has been taken down following an attack that compromised some of the website’s account passwords and may have gained unfettered administrative access.
The SQL-injection attacks on GNU Savannah exploited holes in Savane, the open-source software hosting application that was spun off from SourceForge, Matt Lee, a campaigns manager for the Free Software Foundation, told The Register. The attackers were then able to obtain the entire database of usernames and hashed passwords, some of which were decrypted using brute-force techniques.
Project managers took GNU Savannah offline on Saturday, more than 48 hours after the attack occurred. They expect to bring the site back online on Wednesday, although they’re not guaranteeing it will be fully functional. Out of an abundance of caution, restored data will come from a backup made on November 24, prior to the compromise. Lee said there’s no reason to believe any of the source code hosted on the site was affected by the breach.
“Version control systems that are in place for these projects actually would show a red flag in terms of any changes that they made, and we’ve not seen that, so we believe there’s no issue there,” he explained. What’s more, there’s no indication that the FTP server used to actually transfer source code was compromised, he said.
The attackers used their access to add a hidden static HTML file to a CVS repository and a webpage that defaced the gnu.org home page. After finding a directory that was erroneously set to execute PHP scripts, the hackers also committed a PHP reverse shell script.
