Date : 2017-12-02
CVE-ID : CVE-2017-16641 CVE-2017-16660 CVE-2017-16661 CVE-2017-16785
Package : cacti
Type : multiple issues
Remote : Yes
Link : https://security.archlinux.org/AVG-537
Summary
=======
The package cacti before version 1.1.28-1 is vulnerable to multiple
issues including arbitrary code execution, arbitrary command execution,
cross-site scripting and arbitrary filesystem access.
Resolution
==========
Upgrade to 1.1.28-1.
# pacman -Syu "cacti>=1.1.28-1"
The problems have been fixed upstream in version 1.1.28.
Workaround
==========
None.
Description
===========
- CVE-2017-16641 (arbitrary command execution)
lib/rrd.php in Cacti 1.1.27 allows remote authenticated administrators
to execute arbitrary OS commands via the path_rrdtool parameter in an
action=save request to settings.php.
- CVE-2017-16660 (arbitrary code execution)
Cacti 1.1.27 allows remote authenticated administrators to conduct
Remote Code Execution attacks by placing the Log Path under the web
root, and then making a remote_agent.php request containing PHP code in
a Client-ip header.
- CVE-2017-16661 (arbitrary filesystem access)
Cacti 1.1.27 allows remote authenticated administrators to read
arbitrary files by placing the Log Path into a private directory, and
then making a clog.php?filename= request, as demonstrated by
filename=passwd (with a Log Path under /etc) to read /etc/passwd.
- CVE-2017-16785 (cross-site scripting)
Cacti 1.1.27 has reflected XSS via the PATH_INFO to host.php.
Impact
======
A remote authenticated admin user is able to read arbitrary files,
execute arbitrary code and commands on the affected host. An
unauthenticated user is able to perform cross-site scripting attacks.
