Researcher Report

+++ This bug was initially created as a clone of Bug #13890 +++

I am a vulnerability analyst at VulnCheck responsible for managing our coordinated vulnerability disclosure (CVD) process. A researcher reported this vulnerability affecting IPFire, and VulnCheck is acting as the intermediary and coordinator.

We have tentatively reserved CVE-2025-34222, which have been shared with the researcher but will remain private until public disclosure:

Please be aware that none of this information is public at this moment and all participants are considered under embargo.

VulnCheck follows a 120-day disclosure policy, meaning we allow vendors/maintainers up to 120 days from the time of receiving the report to address the issues before publishing our advisory. For this vulnerability, that 120-day deadline falls on January 21, 2025.

When a user updates the mail server, an HTTP POST request is sent to the Request-URI "/cgi-bin/mail.cgi". The username and password for the mail server are stored into the txt_mailuser and txt_mailpass parameters, respectively.

The values of the txt_mailuser and txt_mailpass parameters are directly displayed without sanitizing for HTML-related characters or strings. This can result in stored cross-site scripting.

The attacker must be authenticated.
