> We're seeing this several times a day on a backend docushare server with modsecurity running in monitor mode (ie non-blocking)
> [Mon Oct 27 20:30:09 2008] [error] [client 10.1.94.38] ModSecurity: Multipart parsing error (init): Multipart: Invalid boundary in C-T (malformed). [hostname "trl.trimble.com"] [uri "/docushare/dscgi/ds.py/ApplyUpload/Collection-59919"] [unique_id "-1HkuAoBPEEAACAe544AAAAa"]
> As with MODSEC-19, the client is the "Docushare client" instead of a Webbrowser. I'll attach the audit log I have (after I strip out the content), but assuming the issue is something to do with Content-Type values, they are:
> Content-Type: multipart/form-data; charset=UTF-8; boundary=354e650f45ec2927
> Content-Type: application/octet-stream
> Content-Type: text/xml;charset=UTF-8
> I have been unable to go production (block mode) with modsecurity on this Docushare backend due to their damn client that I'm tempted to just disable modsec if the User-Agent matches "DsAxess/*". Other than opening up a security risk, should the following achieve that?
> SecRule REQUEST_HEADERS:User-Agent "^DsAxess/" "allow, nolog, ctl:ruleEngine=Off,ctl:auditEngine=Off"
> I'm assuming in all this, that as this isn't a "rule" hit, in block mode this would mean these requests would be error'ing? i.e. I have to turn modsecurity totally off in order for these to work?
> Thanks
