step3 never progress after several hours

afs | Last updated: Oct 10, 2019 02:29AM UTC

Hi, I launch a scan and audit for a website. step1: live passive crawl, step2: live audit from proxy, step3: crawl and audit of website, step1 and step 2 finish in one hour, but in step3, it progress 30%, after five hours, it still progress 30%, never move, I can only scan the website five hours. so how to correct the problem? should I reduce the depth to 5 instead of default 8, or I should adjust other parameter? if step3 is only 30% but step1&2 are finished, did I miss a lot of issues?

Thanks for this report. Do you see any errors in the Dashboard > Event log?

Hi, I'm struggling to understand your testing setup, you say that 'Step 1 & Step 2 finish in one hour' however they are passive tasks that don't have an pre-determined amount of work, they process HTTP requests are they pass through the proxy. Do you mean that you manually crawled the application? Is your scan still progressing after 5 hours or has it stopped? This could be an issue that would require further investigation of your crawler log files.

after 5 hours, I stop it, because it doesn't make sense to scan for 10 hours with no progression.event log is empty, where is the crawer log files located?

You can enable debug mode via Dashboard > New scan > Scan configuration > New > Crawling > Crawl Optimization > click the cog button > Enabling logging. If you could enable logging, reproduce the issue and then send them over to us at support@portswigger.net, we can investigate further from there.
