Vulnerability Report: Misconfigured SPF [No DMARC Record found]
Whitehat Security
Hi Team,
I am an independent security researcher and I have found a bug in your website https://ontobee.org
The details of it are as follows:-
Description:
This report is about a misconfigured SPF record flag, which can be used for malicious purposes as it allows for fake mailing on behalf of respected organizations .
About the Issue:
As i seen the SPF and TXT record for
which is:
DMARC Policy Not Enabled
As u can see that you Weak SPF record, as valid record should be like:-
DMARC policy enabled
What's the issue:
As u can see in the article below the difference between soft-mail and fail you should be using fail, as Soft-mail allows anyone to send spoofed emails from your domains.
Attack Scenario:
An attacker will send phishing mail or anything malicious mail to the victim via mail:
Even if the victim is aware of a phishing attack , he will check the origin email which came from your genuine mail id
ontobee...@googlegroups.com
so he will think that it is genuine mail and get trapped by the attacker.
The attack can be done using any PHP mailer tool like this:-
<?php
$to = "VIC...@example.com";
$subject = "Password Change";
$txt = "Change your password by visiting here - [VIRUS LINK HERE]l";
$headers = "From:
";mail($to,$subject,$txt,$headers);
?>
U can also check your SPF record form:
