Article Content
- •Hacktron exploited a vulnerability in GNU Savannah to gain command execution.
- •The flaw allowed researchers to impersonate Bash's maintainer and escalate privileges.
- •A total of 26 vulnerabilities were identified and patched by the FSF after the incident.
Researchers from Hacktron exploited a vulnerability in GNU Savannah, which hosts Bash and Coreutils, allowing them to execute commands on the server. By using a crafted email address with backticks, they gained superuser access and impersonated Bash maintainer Chet Ramey, although they did not alter the repository. An unpatched kernel flaw from 2023 further granted them root access to the server and a GNU backup host. Hacktron reported the issue to the Free Software Foundation (FSF) on May 11, 2025, leading to a patch within three days. A subsequent audit revealed 26 vulnerabilities, all of which have since been fixed. The FSF stated that no sensitive data or project credentials were believed to have been accessed. This incident highlights the critical nature of securing open-source software infrastructure.
