Re: [galaxy-dev] Galaxy Security Vulnerability - Arbitrary code execution
Thanks David, the issue has been already reported, see https://github.com/galaxyproject/galaxy/issues/3332 , hopefully someone from the Galaxy Team will look into this soon. You can get the patch from GitHub in the mean time, it has been applied to all branches starting from release_14.10 .

If you are on the 'master' branch and wish to remain on your current Galaxy major release, check the 'lib/galaxy/version.py' file to determine your major release version, then update to the appropriate branch: % git fetch origin % git checkout -b release_YY.MM origin/release_YY.MM % git pull 2.

[galaxy-dev] Galaxy Security Vulnerability - Arbitrary code execution
*DESCRIPTION* A security vulnerability was recently discovered by David Wyde in two Galaxy tools that are provided with and enabled by default in the Galaxy server. These vulnerabilities allow malicious actors to execute arbitrary code as the user running the Galaxy server. The vulnerable tools are "Filter GFF data by attribute" and "Filter GFF data by feature count", two tools which share code with each other and the more general "Filter data on any column using simple expressions" tool. The latter was fixed in a previous security disclosure but these GFF variants of the tool were missed when updating the Filter tool. These tools use the Python `eval` and `exec` functions and do not properly sanitize input to these functions. Additionally, an XSS vulnerability with the upload tool: An uploaded file's name was not properly sanitized, and so a specially crafted filename uploaded to the Galaxy server could be used as an XSS attack vector. This vulnerability has already been fixed in the 16.07 and 16.10 Galaxy releases. The Galaxy Committers would like to thank David for disclosing these vulnerabilities. If you discover security vulnerabilities in Galaxy, please report them to the Galaxy Committers at galaxy-committ...@lists.galaxyproject.org. *AFFECTED VERSIONS* These arbitrary code execution vulnerability is present in all known releases of Galaxy using the default tool config or a tool config in which these tools are loaded. To determine if your Galaxy server is affected, check your tool_conf.xml for the following lines: If you are unsure, you can also check to see if the tools have loaded by searching for them in your Galaxy server logs, e.g.: % grep gff_filter paster.log galaxy.tools.toolbox.base DEBUG 2016-12-08 13:25:16,930 Loaded tool id: gff_filter_by_attribute, version: 0.1 into tool panel.. galaxy.tools.toolbox.base DEBUG 2016-12-08 13:25:16,930 Loaded tool id: gff_filter_by_feature_count, version: 0.1 into tool panel.. *IMPACT* This vulnerability can be exploited to execute arbitrary code as the user that runs Galaxy jobs on any system where Galaxy runs those jobs (potentially a cluster). Such code can be used to provide a remote shell to an attacker, or read/write/delete files that the Galaxy user has appropriate permissions on. *SOLUTION* Multiple solutions exist for the arbitrary code execution vulnerability: 1.
