Package: pdns-backend-sqlite3
Version: 2.9.22-8
Severity: normal
The bug is already fixed on upstream (since 2 years) but happens for me with
the current pdns-backend-sqlite3:
I'm running a master nameserver and a slave which get's updated by axfr. I have
a "<script>alert('xss')</script>" TXT-Record (for a POC of triggering XSS on
website) and got this in the slaves log file:
May 4 13:03:22 deimos pdns[6192]: Communicator thread died because of error:
Unable to compile SQLite statement : near "test": syntax error
Seems the content of the record does not get escaped properly.
Steps to reproduce: - Given you have a master and a slave nameserver. - Add a
record with a ' (for example a TXT record) on the master nameserver. - Start a
zone transfer
