Allow Extensions to Bypass Global Timeout

Y-Security | Last updated: Dec 29, 2021 03:53PM UTC

Hi, we're testing a system that does not send a response on successful exploitation. In ActiveScan the Status changes to "Errors: request timeout" and the vulnerability isn't reported. When using a modified activeScan++ Extension I can catch the see that the issue is tracked up until class CustomScanIssue(IScanIssue) --> _init__( However, the issue does not adds into "Issue Activity" overview. It can be reproduced with the latest activeScan++ Extension when scanning against the vuln Log4j PoC from here: https://github.com/leonjza/log4jpwn Result: no Log4Shell issue is reported Expected result: Log4Shell issue is reported Feature request: Make the Request interface available independently from the Response / Allow to drop responses after an extension defined timeout. Maybe bug report: it feels like the issue should be flagged even if there is an timeout (the issue has been confirmed, it fails to add it)

Hi,

This will be looked at in an upcoming extender update, I don't have an ETA at this current time, but I will update this thread when available.

In the meantime, we would recommend taking a look at the Log4Shell Scanner extension, at least in respect of your Log4j use case.

Thanks
