All supported architectures
Cacti has three vulnerabilities that could allow shell command execution or
Cacti is a web-based network graphing and reporting tool.
rgod discovered that the Cacti cmd.php and copy_cacti_user.php scripts
do not properly control access to the command shell, and are remotely
accessible by unauthenticated users. This allows SQL injection via
cmd.php and copy_cacti_user.php URLs. Further, the results from the
injected SQL query are not properly sanitized before being passed to a
command shell. The vulnerabilities require that the
"register_argc_argv" option is enabled, which is the Gentoo default.
Also, a number of similar problems in other scripts were reported.
These vulnerabilties can result in the execution of arbitrary shell
commands or information disclosure via crafted SQL queries.
There is no known workaround at this time.
All Cacti users should upgrade to the latest version:
