Apache Linkis Basic management services: Privilege Escalation Attack vulnerability

Vulnerability

Overview

CVE-2024-27181 is a privilege escalation vulnerability in Apache Linkis Basic management services affecting versions up to and including 1.5.0. The root cause lies in insufficient access controls that allow a user who is already a trusted account to escalate their privileges and gain access to Linkis's Token information [2][3].

Exploitation

Conditions

To exploit this vulnerability, an attacker must already possess a trusted account within the Linkis environment. No additional authentication bypass or network position is required beyond that initial trust. The attack surface is the Basic management services component, which handles administrative functions [2][3].

Impact

Successful exploitation enables the attacker to retrieve Token information, which could be leveraged to impersonate other users or services, potentially leading to further unauthorized actions within the Linkis ecosystem [1][2][3].

Mitigation

The Apache Linkis project has addressed this issue in version 1.6.0. Users are strongly advised to upgrade to this version or later. No workarounds have been provided, and the vulnerability is not currently listed in CISA's Known Exploited Vulnerabilities catalog [2][3].
