Critical

Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N

Name of the Vulnerable Software and Affected Versions Apache Linkis versions 1.3.1 and earlier

Description The issue arises due to the default token generated by Linkis Gateway deployment being too simple, making it easy for attackers to obtain the default token for the attack. Generation rules should add random values.

Recommendations For Apache Linkis versions 1.3.1 and earlier, upgrade the version of Linkis to version 1.3.2 and modify the default token value. As a temporary workaround, consider modifying the default token value to add random values until a patch is available. Restrict access to the default token to minimize the risk of exploitation.
