pyasn1-0.3.5: Error: can only concatenate tuple (not "str") to tuple

[sho-luv]

So when I run the following command
GetUserSPNs.py domain/user:password

Impacket v0.9.16-dev - Copyright 2002-2017 Core Security Technologies

ServicePrincipalName Name MemberOf PasswordLastSet LastLogon

---

<information no problem!>

GetUserSPNs.py domain/user:password -request

ServicePrincipalName Name MemberOf PasswordLastSet LastLogon

---

<information no problem!>

however I then get this error:

can only concatenate tuple (not "str") to tuple

any ideas as to what sort of data I'm getting back that might cause this?

Hey @sho-luv

What pyasn1 version you have installed in your system? That might be the problem. You can quickly check it from your python console:

import pyasn1
pyasn1.__version__

[sho-luv]

Apparently I'm running 0.3.5

python
Python 2.7.13 (default, Jan 19 2017, 14:48:08) 
[GCC 6.3.0 20170118] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pyasn1
>>> 
>>> pyasn1.__version__
'0.3.5'
>>>

Certainly I can reproduce that in pyasn1 0.3.5. While I take a look at it, please install an older version for that library.
pyasn1-0.3.3 should work.

Just tested pyasn1-0.3.4 and it works as well. Something's wrong with the latest version and our code.

[sho-luv]

Thanks. Rolling it back works for me as well. For now I use the workaround
pip install pyasn1==0.3.3

New pyasn1 release (0.3.6) tagged with this fix. Closing this one. Thanks @sho-luv for reporting it and @etingof for the quick turnaround!. Closing.
