Overview

This is a utility to parse Fortify FPR files and generate meaningful output that can be used in automated processes or reports.

The summary statistics can print out just the vulnerability counts so you can do things like flag apps that have > 0 critical or high vulnerabilities.

The vulnerability summaries output can be used to send to developers who may not have HPE Fortify Auditworkbench or access to the Fortify SSC UI (e.g. vendors/contractors). It could also be used as input to a script to auto-assign vulnerabilities to dev teams. Or it could just let you pivot around the vulnerability statistics in an application.

Fortify SSC UI has a REST interface now that may be useful instead of this tool, although it may be far slower for large projects than just parsing the FPR file. This utility also works offline if you have copies of FPR files already downloaded.

About FPR Files

Fortify FPR files are just zip archives with various XML files inside. The parsing of the FPR file for this utility was mostly reverse-engineering and comparing to the Fortify results. I was able to get Fortify tech support to provide some of the calculations for the derived values that are used to calculate the criticality (aka Fortify Priority Order) though.

There is a secret keyboard combination in Auditworkbench COMMAND + OPTION + SHIFT + F that provides a dump of the known attributes of a vulnerability instance that you can use for filters.

Limitations

This utility currently implements very limited support for Fortify filtering syntax so won't generate counts for all but a couple of filter scenarios. Would be nice to add more use cases at some point. The FilterQuery class implements evaluation logic of the query and supports only:

• Substring match
• Negated substring match

e.g. "Any vulnerability instance with a category containing the word Path"

category:Path

or "Any vulnerability instance that is not marked as Exploitable"

analysis:!Exploitable

This utility also doesn't support custom filter sets that can vastly change the vulnerability visibility and classifications. It just uses the Default filter set in the FPR. Would not be difficult to expose the ability to specify a non-default filter set, perhaps even by the string name.

Tips

Watch out if you are using this to process FPR files generated directly from a scan before they have been uploaded to Fortify SSC. The vulnerability counts you see will not likely match up to what is on the Fortify SSC server due to:

• Not having the same Project Template applied to the generated FPR as is applied and enforced on the Fortify SSC server (this can change visibility/filtering of vulnerabilities, reclassify vulnerabilities to different folders, different filter sets, etc. that all can result in different vulnerability counts)
• Not having any of the auditing information available or suppression information that could change the vulnerability counts.

Installation

Install to a user directory on OSX:

	python setup.py install --user --prefix=

Using the command-line utility

Usage help

usage: Print statistics from a Fortify FPR file [-h] -f FPR [-p] [-c] [-s]
                                                [--high_priority_only] [-v]

optional arguments:
  -h, --help            show this help message and exit
  -f FPR, --file FPR    generate stats for FPR
  -p, --project_info    print project and scan info
  -c, --vuln_counts     print vulnerabilities as CSV output
  -s, --vuln_summaries  print vulnerability details as CSV output
  --high_priority_only  For vulnerability summaries: Filters only High
                        Priority relevant issues, which includes Critical/High
                        and excludes anything suppressed, removed, hidden, NAI
  -v, --verbose         print verbose/debug output

Print out vulnerability counts for an FPR

$ fprstats.py -f ~/Downloads/MyApp.fpr 
Got [108] issues, [0] hidden, [0] NAI, [0] Suppressed, [0] Removed

Print out vulnerability counts as CSV (machine-readable) format

$ fprstats.py -f ~/Downloads/MyApp.fpr -c
Got [108] issues, [0] hidden, [0] NAI, [0] Suppressed, [0] Removed
Critical, High, Medium, Low
0, 15, 0, 93

Print a report containing vulnerability summaries as CSV format

$ fprstats.py -f ~/Downloads/MyApp.fpr -s
Got [108] issues, [0] hidden, [0] NAI, [0] Suppressed, [0] Removed
file_line,path,id,kingdom,type_subtype,severity,nai,filtered,suppressed,removed
MyService.java:100,src/main/java/com/example/www/myapp/services/MyService.java,1BE7DEE63734F7EC117948FACE57A977,Errors,Poor Error Handling: Overly Broad Throws,Low,False,V,False,False
....

You can redirect the CSV outputs to a file:

$ fprstats.py -f ~/Downloads/MyApp.fpr -c > /tmp/MyApp.csv
Got [108] issues, [0] hidden, [0] NAI, [0] Suppressed, [0] Removed

MyApp.csv contains:

$ cat /tmp/MyApp.csv
Critical, High, Medium, Low
0, 15, 0, 93

Getting verbose log output to stderr

$ fprstats.py --high_priority_only -s -f ~/Downloads/MyApp.fpr -v > ~/Downloads/expweb-high-priority.csv 

Would generate output like:

Using the module in another python application

	from fortify import ProjectFactory

	project = ProjectFactory.create_project("some/path/to/file.fpr")
    
    # Now, print vulnerability summaries, etc.
    project.print_vuln_counts()
