Subject: CVE Request: smokeping incomplete fix for CVE-2012-0790
Hello Kurt, Steve, all,
I am requesting a 2012 CVE for an incomplete security fix in smokeping,
fixed in version 2.6.9.
CVE-2012-0790 was assigned to smokeping for XSS flaws.
The fix for CVE-2012-0790 in smokeping 2.6.7 was incomplete. The
filtering used this blacklist:
$mode =~ s/[<>&%]/./g;
The version in 2.6.9 uses the following blacklist:
my $xssBadRx = qr/[<>%&'";]/;
(', ", and ; have been added. When it is used, blacklist chars are now
turned to _ rather than . ) The 2.6.9 version prevents escaping <html
attribute="..."> via " characters.
The incomplete fix is in 2.6.7 and 2.6.8.
This flaw was discovered by Florian Weimer [1] in 2012 and brought to
our attention [2] in 2013.
The upstream CHANGES [3] file includes, in part:
--------------------------------------------------
2013/03/04 - released version 2.6.9
* be more careful about preventing xss attacks, re http://bugs.debian.org/659899 (tobi)
--------------------------------------------------
I have not found an up-to-date online browsable source.
Thanks
