Analyst Synthesis

Technical analysis, exploit verification, and patch instructions for CVE-2025-61541 impacting webmin webmin. Evaluated with CVSS Base Score of 7.1 (HIGH).

Original NVD Description

Source: NIST NVD
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.
