Scan errors in Burp

Vinod | Last updated: Apr 15, 2015 04:14PM UTC

I ran an active scan using Burp. The scan was abandoned due to multiple errors. I would like view the error logs so that I could figure out what went wrong. How do I check these errors?

The Alerts tab in Burp will contain details of any applicable errors. Scans being abandoned due to too many errors normally occurs because of failed or timed out network connections. If you are seeing lots of network errors, you can configure how many retries Burp will perform and how long it will wait before retries at Scanner / Options / Active Scanning Engine. You might also need to decrease the number of scan threads if the application or network is being overloaded.

Hi, I use the "Crawl and Audit - Lightweight" scan configuration for scanning a few endpoints. However, the scan could not be completed due to numerous network errors and entered a paused state. Could you explain how network errors impact a running scan? On a different note, I need guidance on how to adjust the manual update process for a system-scheduled time.

I appreciate the clarification on the first part. I'm seeking guidance on automating the update process for Burp Suite Professional to execute automatically at scheduled times without requiring manual intervention. Specifically, I'm interested in whether Burp Suite Professional offers a built-in feature to check for updates and apply them according to a predefined schedule. This would ensure updates occur smoothly without unexpected interruptions, allowing me to complete them during off-peak hours.

Hi Sreepriya,

I am afraid there is no such process. You only have the option to delay the update by a week or for the current version. I would suggest delaying the update for the current version so that Burp doesn't update automatically, and during the off-peak hours, you can manually update the tool.

I hope this helps.

Thank you for your response. I attempted to access the Alerts tab to investigate the network error as suggested in the above comment, but couldn't locate it in Burp Professional Edition. Additionally, despite adjusting the timeout request settings for both audit and crawl to a limit of 100 as instructed, my scan still paused unexpectedly. Could you please provide further guidance on locating the Alerts tab in Burp Professional Edition and any additional steps I can take to prevent scans from pausing? <API output> { "scan_metrics": { "current_url": "", "crawl_requests_made": 1275, "crawl_network_errors": 0, "crawl_unique_locations_visited": 12, "crawl_requests_queued": 0, "audit_queue_items_completed": 0, "audit_queue_items_waiting": 28, "audit_requests_made": 701, "audit_network_errors": 29, "issue_events": 25, "crawl_and_audit_caption": "Paused task due to: Reached time limit for task", "crawl_and_audit_progress": 92, "total_elapsed_time": 900 }, "task_id": "3", "scan_status": "paused", "message": "", "error_code": 0

Hi Sreepriya,

You don't need to change the timeout settings rather the error handling settings. Please read the message again and follow the instructions to increase the limit. If you are still unsure about what you need to do, please email me at support@portswigger.net and I will help you.
