Severity: Moderate
CVSS 3.1: 6.1 (medium) CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
Affected versions:
- Apache Roller 6.1.5
Description:
Improper Neutralization of Input During Web Page Generation ('Cross-site
Scripting') in Apache Roller 6.1.5 allows an unauthenticated remote attacker to
store a crafted comment-author URL through the incoming Trackback endpoint when
a published entry accepts comments and Trackbacks. The shipped Trackback,
verification and moderation defaults allow the value to be approved and
rendered as an active link; a visitor who clicks the link executes script in
the weblog's origin. Users are recommended to upgrade to Apache Roller 6.1.6 or
later, which removes incoming Trackback support and suppresses non-HTTP(S)
comment-author links. Users unable to upgrade should disable Trackbacks and
remove untrusted Trackback comments.
