Error: failed to write output: open tfsec_checks.markdown: permission denied

[lhoupert]

Hi, I encountered a write permission issue when trying to output the tfsec checks.

I can run the command below succesfully:
docker run --rm -it -v "$(pwd):/src" aquasec/tfsec /src --include-ignored

But if I run

 docker run --rm -it -v "$(pwd):/src" aquasec/tfsec /src  --out tfsec_checks -f markdown,html

or

docker run --rm -it -v "$(pwd):/src" aquasec/tfsec /src  --out "tfsec_checks" -f "markdown,html"

I receive this error:

=====================================================
tfsec is joining the Trivy family

tfsec will continue to remain available
for the time being, although our engineering
attention will be directed at Trivy going forward.

======================================================
Error: failed to write output: open tfsec_checks.markdown: permission denied

Is there an easy way to fix this?

I had no problem running kics in a container an exporting the report with the command below:

docker pull checkmarx/kics:latest
docker run -v .:/data checkmarx/kics:latest scan -p "/data" --report-formats "json,html" -o "/data/kics_scan_results"

Thank you!

As shown in the output you shared, our efforts have moved to Trivy (aquasecurity/tfsec#1994). Have you had any issues migrating to Trivy?

Furthermore I don't think this error is related to either tfsec or Trivy but rather sounds like you might have permissions issues with the directory you're working with?

Yes I tried trivy but doesn't seem to be working on my laptop due to some tls error:

docker run --rm -it -v "$(pwd):/src" aquasec/trivy fs /src  -o "trivy_checks"

I have not problem generating a report using the kics docker image working on the same repository

docker run -v .:/data checkmarx/kics:latest scan -p "/data" --report-formats "json,html" -o "/data/kics_scan_results"

Which make me believe it comes from the tfsec docker image. Anyway I am very happy with checkov and kics results so I may just go with them.

NOTE: If I want to make the trivy docker image work on my machine, I need to create a custom docker image where I copy my SSL certificate in it:

FROM aquasec/trivy

COPY zscaler.pem ./zscaler.pem
RUN tee -a /etc/ssl/certs/ca-certificates.crt < ./zscaler.pem
ENV REQUESTS_CA_BUNDLE=/etc/ssl/certs/ca-certificates.crt
ENV SSL_CERT_FILE=/etc/ssl/certs/ca-certificates.crt
ENV NODE_EXTRA_CA_CERTS=/etc/ssl/certs/ca-certificates.crt

Hi @lhoupert !

Maybe this will help you?

[lhoupert]

Oh thank you I missed that!
I used it as an environment variable:
I tried :

docker run --rm -it -v "$(pwd):/src" -e TRIVY_INSECURE='true' aquasec/trivy fs --scanners vuln,misconfig,secret /src

but now I have another error:

docker run --rm -it -v "$(pwd):/src" -e TRIVY_INSECURE='true' aquasec/trivy fs --scanners vuln,misconfig,secret /src
