The security issue is caused due to the "reaction" plugin allowing unprivileged IRC users to set up arbitrary "cmd" reactions, which can be exploited to e.g. execute arbitrary rbot commands with escalated privileges by setting up a specially crafted "cmd" reaction and e.g. tricking the bot owner into triggering the malicious reaction. Note: In unstable versions this may also allow the execution of arbitrary Ruby code. The security issue is confirmed in version 0.9.14. Other versions may also be affected. SOLUTION: Fixed in the GIT repository. http://ruby-rbot.org/rbot-trac/changeset/a9565be1c9d5549b1cbc058bb0a097011e1dd778/ http://ruby-rbot.org/rbot-trac/changeset/7d2f231d66e125428c7c9a72588ecae93a11f987/ http://ruby-rbot.org/rbot-trac/changeset/66a33c3f8adaf0ebcd3c72298c6ad07c0561dc90/ PROVIDED AND/OR DISCOVERED BY: Matthias -apoc- Hecker ORIGINAL ADVISORY: http://archives.neohapsis.com/archives/fulldisclosure/2010-02/0426.html http://ruby-rbot.org/rbot-trac/changeset/a9565be1c9d5549b1cbc058bb0a097011e1dd778/ http://ruby-rbot.org/rbot-trac/changeset/7d2f231d66e125428c7c9a72588ecae93a11f987/ http://ruby-rbot.org/rbot-trac/changeset/66a33c3f8adaf0ebcd3c72298c6ad07c0561dc90/ ---------------------------------------------------------------------- About: This Advisory was delivered by Secunia as a free service to help private users keeping their systems up to date against the latest vulnerabilities.
