{"id":"UBUNTU-CVE-2017-8295","details":"WordPress through 4.7.4 relies on the Host HTTP header for a password-reset e-mail message, which makes it easier for remote attackers to reset arbitrary passwords by making a crafted wp-login.php?action=lostpassword request and then arranging for this message 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. Exploitation is not achievable in all cases because it requires at least one of the following: (1) the attacker can prevent the victim from receiving any e-mail messages for an extended period of time (such as 5 days), (2) the victim's e-mail system sends an autoresponse containing the original message, or (3) the victim manually composes a reply containing the original message.","modified":"2025-10-24T04:46:18Z","published":"2017-05-04T14:29:00Z","upstream":["CVE-2017-8295"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2017-8295"},{"type":"REPORT","url":"https://exploitbox.io/vuln/WordPress-Exploit-4-7-Unauth-Password-Reset-0day-CVE-2017-8295.html"},{"type":"REPORT","url":"https://www.exploit-db.com/exploits/41963/"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2017-8295"}],"affected":[{"package":{"name":"wordpress","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/wordpress@4.4.2+dfsg-1ubuntu1?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.3+dfsg-1","4.3.1+dfsg-1","4.4+dfsg-1","4.4.1+dfsg-1","4.4.2+dfsg-1","4.4.2+dfsg-1ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_version":"4.4.2+dfsg-1ubuntu1","binary_name":"wordpress"},{"binary_version":"4.4.2+dfsg-1ubuntu1","binary_name":"wordpress-l10n"},{"binary_version":"4.4.2+dfsg-1ubuntu1","binary_name":"wordpress-theme-twentyfifteen"},{"binary_version":"4.4.2+dfsg-1ubuntu1","binary_name":"wordpress-theme-twentyfourteen"},{"binary_version":"4.4.2+dfsg-1ubuntu1","binary_name":"wordpress-theme-twentysixteen"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2017/UBUNTU-CVE-2017-8295.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N"},{"type":"Ubuntu","score":"medium"}]}
