Title:WordPress Password Reset CVE-2017-8295 Security Bypass Vulnerability - Linux
Summary:WordPress is prone to a security bypass vulnerability.
Description:Summary:
WordPress is prone to a security bypass vulnerability.

Vulnerability Insight:
The flaws exist because WordPress relies on the Host HTTP header for a password-reset e-mail message,
which makes it easier for user-assisted remote attackers to reset arbitrary passwords by making a crafted wp-login.php?action=lostpassword
request and then arranging for this e-mail to bounce or be resent, leading to transmission of the reset key to a mailbox on an
attacker-controlled SMTP server. This is related to problematic use of the SERVER_NAME variable in wp-includes/pluggable.php in
conjunction with the PHP mail function.

Vulnerability Impact:
Attackers can exploit this issue to bypass certain security restrictions to perform unauthorized actions.
This may aid in further attacks.

Affected Software/OS:
WordPress versions 4.7.4 and prior.

Solution:
No known solution was made available for at least one year since the disclosure of this vulnerability.
Likely none will be provided anymore. General solution options are to upgrade to a newer release, disable respective features, remove the
product or replace the product by another one.

A workaround is to enable UseCanonicalName to enforce static SERVER_NAME value.

CVSS Score:
4.3
