Project Munin · Munin · CVE-2017-6188
**Name of the Vulnerable Software and Affected Versions**
Munin versions prior to 2.999.6
**Description**
The issue allows for local file write access when CGI graphs are enabled. By setting multiple `upper limit` GET parameters, it is possible to overwrite any file accessible to the `www-data` user. This can be achieved through specific API endpoints, although the exact endpoints are not specified.
**Recommendations**
For versions prior to 2.999.6, update to version 2.999.6 or later to resolve the issue.
As a temporary workaround, consider disabling CGI graphs until a patch is available.
Restrict access to files accessible by the `www-data` user to minimize the risk of exploitation.
