Yes. Consult the release notes for NetView 7.1. This is part of the
NetView security fix for CERT advisory
http://www.cert.org/advisories/CA-2001-24.html
(Note however that the sed expressions in the release notes may not be
reliable. )
Any character that is not alphanumeric is a candidate for either being
replaced with an underscore (_) or being prepended with a baskslash
before being handed off to any external shell processes. Hyphens and
periods are legal hostname characters. I believe both of those by
default will get backslashed rather than replaced with an _
Adding and tweaking the AdditionalLegalTrapCharacters environment
variable in /usr/OV/bin/netnmrc.pre and recycling all daemons with
# ovstop;ovstop nvsecd;/etc/netnmrc
will allow you to control this. Your current settings can be viewed
at the top of /usr/OV/log/nvaction.alog if you have that logging
enabled.

Consider modifying your action scripts that send postemsg's to TEC
cleanse the varbind data of these backslashes when necessary. For
example, to remove backslashes from legal non-alphanumerics in
hostnames contained in varbinds 2 3 and 4:
########################################################################
# replace \. \- with . - respectvely.
########################################################################
NVATTR_2=$(/usr/bin/echo "$NVATTR_2" | /usr/bin/sed 's:\\\([-\.]\):\1:g')
NVATTR_3=$(/usr/bin/echo "$NVATTR_3" | /usr/bin/sed 's:\\\([-\.]\):\1:g')
NVATTR_4=$(/usr/bin/echo "$NVATTR_4" | /usr/bin/sed 's:\\\([-\.]\):\1:g')
