CVE-2026-67178

Estado: AplazadaAlta (7.8)—

MISP installation scripts generated an Apache HTTP virtual-host configuration containing an incorrectly formatted HTTP-to-HTTPS redirect:

Redirect permanent / https://misp.example

Apache’s Redirect directive appends any portion of the requested path that follows the matched prefix to the configured destination URL. Because the destination did not end with /, attacker-controlled path content was appended directly to the hostname rather than to its URL path.

For example, a request resembling:

http://misp.example/@attacker.example/

could result in a redirect resembling:

https://misp.example@attacker.example/

Leer descripción completaMostrar menos

Under standard URL parsing, misp.example is interpreted as user information and attacker.example as the destination host. An unauthenticated remote attacker could therefore construct a URL hosted under the legitimate MISP domain that redirects users to an attacker-controlled website.

The vulnerability could be used for phishing, credential collection, or potentially disclosing sensitive query-string information preserved during the redirect. Exploitation requires a user to follow the crafted HTTP URL.

The fix adds the missing trailing slash to the redirect destination, ensuring that appended request data remains part of the path on the configured MISP host.

Existing installationsExisting MISP installations should review their Apache HTTP virtual-host configuration and ensure that the HTTPS redirect destination ends with a trailing slash:

Redirect permanent / https://misp.example/

After updating the configuration, validate it with apachectl configtest and reload or restart Apache for the change to take effect
