Understanding CVE-2023-32696

CVE-2023-32696 is a security vulnerability identified in CKAN, an open-source data management system used for data hubs and portals. The vulnerability allowed the

ckan

user to have excessive permissions, including the ability to own critical files and use sudo, potentially leading to code execution or privilege escalation.

What is CVE-2023-32696?

CKAN versions prior to 2.9.9 and 2.10.1 were affected by CVE-2023-32696. The issue mainly revolved around the

ckan

user having inappropriate privileges within the docker container, making the system vulnerable to unauthorized access and potential attacks.

The Impact of CVE-2023-32696

The vulnerability posed a high risk as it enabled attackers to execute malicious code or escalate privileges, compromising the confidentiality, integrity, and availability of the system. It could have severe consequences if exploited by threat actors.

Technical Details of CVE-2023-32696

CVE-2023-32696 was classified under CWE-269 (Improper Privilege Management) due to the mismanagement of privileges associated with the

ckan

user in CKAN. The CVSS v3.1 base score of the vulnerability was 8.8 (High), indicating a significant security risk.

Vulnerability Description

Prior to versions 2.9.9 and 2.10.1, the

ckan

user in CKAN had excessive permissions, allowing for unauthorized access and potential privilege escalation. This misconfiguration posed a serious security threat to the system.

Affected Systems and Versions

The vulnerability impacted CKAN versions less than 2.9.9 and between 2.10.0 and 2.10.1. Users operating these versions were at risk of exploitation and needed to take immediate action to secure their systems.

Exploitation Mechanism
