Title:       EGI SVG Advisory [TLP:WHITE] 'Low' Risk - Panda Pilot factory payload verification

Date:        2016-05-25 

Affected Software and Risk

'Low' Risk Vulnerability concerning Panda Pilot factory payload verification

Actions Required/Recommended

No action is recommended - this is for information only 

Affected software

Panda software installed via means other than via CVMFS.  

More Information 

The PanDA (Production and Distributed Analysis System) is a framework developed by the LHC ATLAS 
experiment to handle pilot jobs in a distributed computing environment. [R 1] 

A vulnerability has been found where Panda does not carry out any verification of software tarballs. 

Panda download their jobwrapper code tarballs over HTTP with no suitable verification that it hasn't 
been tampered with (and then execute the contained code).
In principle this opens the door to DNS and MITM attacks, which are unlikely in our environment. 

Panda is migrating to use software installation from the CVMFS repository, which is considered to 
be an acceptable means of installation across the project. The move to installation via CVMFS is 
considered to be a satisfactory solution. 

Risk category

This issue has been assessed as 'Low' Risk by the EGI SVG Risk Assessment Team.
