This is the official release announcement for IPFire 2.19 – Core Update 101.
This update contains various security fixes and bug fixes. These are the changes
Cross-Site-Scripting Vulnerability and Remote Code Execution in the IPFire Web
Yann Cam, an independent security researcher, discovered  to vulnerabilities
in the IPFire Web User interface that could be used in some circumstances. In
the ipinfo.cgi file, a cross-site scripting attack could be executed on logged
in users and in two more CGI files (proxy.cgi and chpasswd.cgi), a remote code
execution vulnerability was found which allowed attackers to use the
aforementioned cross-site scripting attack to execute shell commands as an
unprivileged user on the IPFire system.
These attacks are only possible to perform on an admin’s computer and only in
that instance when the administrator is logged in to the web user interface. Of
course we recommend to install this update as soon as possible to close these
We would like to thank Yann to look closely at the IPFire code and help us to
improve it and we would like to invite everyone who wants to do so as well and
report any bugs or security vulnerabilities that they may find.
Security Fixes in other packages
The web proxy squid was patched against a vulnerability filed under CVE-2016-
3947 that cannot be exploited in IPFire.
Connection Tracking Issues
On many systems, some protocols that require special care by the connection
tracking implementation failed to traverse NAT. These include FTP, SIP and PPTP
and where unfortunately not discovered in the testing phase of Core Update 100
Those connection tracking helpers are now enabled by default on all migrated
