Severity: Important
CVSS 3.1: 7.7 (high) CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N
Affected versions:
- Apache Roller 6.1.5
Description:
Improper Restriction of XML External Entity Reference in Apache Roller 6.1.5
allows a user with entry-editing rights on a weblog to cause the server to
parse an attacker-influenced trackback response with an XML parser that does
not disable external entity resolution, leading to disclosure of files readable
by the Roller process. The Trackback control is hidden in the standard UI, but
its action remains directly reachable, and no non-default server configuration
is required. Users are recommended to upgrade to Apache Roller 6.1.6 or later,
which removes the outbound trackback response parser.
