Severity: Moderate
CVSS 3.1: 9.9 (critical) CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
Affected versions:
- Apache Roller 6.1.5
Description:
Missing Authorization in Apache Roller 6.1.5 allows an authenticated user to
read, modify, or delete weblog content belonging to other weblogs through the
legacy XML-RPC Blogger and MetaWeblog APIs, because the handlers authenticate
the caller but do not verify the caller's permission on the weblog or entry
actually affected. Only installations that enable the non-default global
XML-RPC setting are affected; the per-weblog API flag defaults to enabled for
UI-created weblogs. Users are recommended to upgrade to Apache Roller 6.1.6 or
later, which applies an explicit per-method permission check, or to keep the
XML-RPC feature disabled.
