Description

Webmin 2.510 is vulnerable to a Host Header Injection in the password reset functionality (forgot_send.cgi). The reset link sent to users is constructed using the HTTP Host header via get_webmin_email_url(). An attacker can manipulate the Host header to inject a malicious domain into the reset email. If a victim follows the poisoned link, the attacker can intercept the reset token and gain full control of the target account.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. A user must be tricked into taking some action. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality low, integrity none, availability high.
