Deeper analysisAI

CVE-2024-13277 is an Incorrect Authorization vulnerability (CWE-863) in the Drupal Smart IP Ban module that allows forceful browsing. This issue affects Smart IP Ban versions from 7.x-1.0 up to but not including 7.x-1.1.

The vulnerability carries a CVSS v3.1 base score of 9.1 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N), meaning unauthenticated remote attackers require only network access and low attack complexity with no user interaction. Exploitation enables high-impact compromise of confidentiality and integrity, such as unauthorized access to sensitive data or modification of resources, while availability remains unaffected.

The Drupal security advisory SA-CONTRIB-2024-041 at https://www.drupal.org/sa-contrib-2024-041 provides details on the vulnerability and mitigation, which involves updating to Smart IP Ban version 7.x-1.1 or later.
