[GLSA-200409-15] Webmin, Usermin: Multiple vulnerabilities in Usermin Vulnerability Scan
Vulnerability Scan Summary
Webmin, Usermin: Multiple vulnerabilities in Usermin
Detailed Explanation for this Vulnerability Test
The remote host is affected by the vulnerability described in GLSA-200409-15
(Webmin, Usermin: Multiple vulnerabilities in Usermin)
There is an input validation bug in the webmail feature of Usermin.
Additionally, the Webmin and Usermin installation scripts write to
/tmp/.webmin without properly checking if it exists first.
Impact
The first vulnerability allows a remote attacker to inject arbitrary shell
code in a specially-crafted e-mail. This could lead to remote code
execution with the rights of the user running Webmin or Usermin.
The second could allow local users who know Webmin or Usermin is going to
be installed to have arbitrary files be overwritten by creating a symlink
by the name /tmp/.webmin that points to some target file, e.g. /etc/passwd.
Workaround
There is no known workaround at this time.
