biopython is vulnerable to Code Injection
88
High Risk
This Affects:
biopythonTL;DR
The Bio.Nexus NEXUS parser evaluates values taken from parsed phylogenetic data files using Python's built-in eval. A crafted NEXUS file can place attacker-controlled content into a field the parser passes to eval, so parsing the file executes arbitrary Python and can run shell commands. The fix removes the use of eval from the NEXUS parser and handles values without dynamic evaluation.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and your application parses NEXUS files that come from untrusted sources.
Background info
biopython is vulnerable to Code Injection in versions 0.0.1 - 1.87.0.
How to fix this
Upgrade the biopython library to the patch version.
