Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in Apache Roller 6.1.5 allows a remote attacker to perform reflected cross-site scripting through the optional LDAP comment authenticator, which writes request parameter values into its HTML form without escaping. This affects only sites configured to use LdapCommentAuthenticator, and a victim whose session has already loaded the authenticator form must follow a crafted link. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which escapes the reflected values.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in Apache Roller 6.1.5 allows an anonymous remote attacker to store a comment containing a javascript: URI link that survives HTML comment formatting and can execute script in the browser of a visitor who clicks it. This affects only sites that enable HTML in comments (users.comments.htmlenabled=true) together with the HTMLSubset comment formatter; comment moderation, where enabled, delays publication. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which restricts restored links to http, https and mailto URIs.

Improper neutralization of input in Apache Roller 6.1.5 allows an anonymous remote attacker to store a crafted comment-author URL that can execute script in the session of a weblog moderator or global administrator when the comment management page is viewed. This affects sites that permit comments on at least one weblog and whose moderator subsequently reviews the submitted comment; no non-default server setting is required. Users are recommended to upgrade to Apache Roller 6.1.6 or later.

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.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in Apache Roller 6.1.5 allows a user with media-upload rights to store active content on Roller's origin, because the media upload feature trusts the upload-supplied content type and serves the stored file back with that type. A victim who opens the uploaded file executes the stored script. Media uploads are disabled by default; only installations that enable them are affected, and the shipped type restrictions do not block active content once uploads are on. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which derives the stored type from file content and serves non-image media as a download.

Exposure of Sensitive Information to an Unauthorized Actor in Apache Roller 6.1.5 allows a weblog administrator to read files on the application classpath, including Roller configuration files containing secrets, by authoring a Velocity template that uses an include directive to load a classpath resource outside the theme namespace. Roller treats weblog administrators as untrusted and enables a Velocity sandbox, but the include and parse directives are not confined by it. No non-default configuration is required; this affects any weblog whose administrator can author templates. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which confines includes to the active theme and removes classpath resource loading from weblog rendering.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in Apache Roller 6.1.5 allows a remote attacker to perform reflected cross-site scripting against a visitor to a weblog using the bundled frontpage theme, by supplying a crafted blog-directory parameter that the directory page reflects without proper escaping. This affects only weblogs that use the bundled frontpage theme, and a victim must follow a crafted link for the script to execute. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which validates and contextually escapes the reflected parameter.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in Apache Roller 6.1.5 allows a user with authoring rights on a weblog to store crafted content that is later written into the authoring UI's JavaScript string literals and markup sinks without proper encoding, causing the stored script to execute in another author's or administrator's browser. No optional feature or non-default configuration is required; this affects weblogs with multiple authors or administrators who are not mutually trusted. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which moves those values out of JavaScript literals and writes them as text.

Cross-site Resource Forgery (CSRF), Privilege escalation vulnerability in Apache Roller. On multi-blog/user Roller websites, by default weblog owners are trusted to publish arbitrary weblog content and this combined with a deficiency in Roller's CSRF protections allowed an escalation of privileges attack. This issue affects Apache Roller before 6.1.4.

Roller users who run multi-blog/user Roller websites are recommended to upgrade to version 6.1.4, which fixes the issue.

Roller 6.1.4 release announcement:  https://lists.apache.org/thread/3c3f6rwqptyw6wdc95654fq5vlosqdpw

Insufficient input validation and sanitation in Profile name & screenname, Bookmark name & description and blogroll name features in all versions of Apache Roller on all platforms allows an authenticated user to perform an XSS attack. Mitigation: if you do not have Roller configured for untrusted users, then you need to do nothing because you trust your users to author raw HTML and other web content. If you are running with untrusted users then you should upgrade to Roller 6.1.3.

This issue affects Apache Roller: from 5.0.0 before 6.1.3.

Users are recommended to upgrade to version 6.1.3, which fixes the issue.

Insufficient input validation and sanitation in Weblog Category name, Website About and File Upload features in all versions of Apache Roller on all platforms allows an authenticated user to perform an XSS attack. Mitigation: if you do not have Roller configured for untrusted users, then you need to do nothing because you trust your users to author raw HTML and other web content. If you are running with untrusted users then you should upgrade to Roller 6.1.2 and you should disable Roller's File Upload feature.

A Reflected Cross-site Scripting (XSS) vulnerability exists in Apache Roller. Roller's Math Comment Authenticator did not property sanitize user input and could be exploited to perform Reflected Cross Site Scripting (XSS). The mitigation for this vulnerability is to upgrade to the latest version of Roller, which is now Roller 5.2.3.

Multiple cross-site scripting (XSS) vulnerabilities in Apache Roller before 5.0.2 allow remote attackers to inject arbitrary web script or HTML via vectors related to the search results in the (1) RSS and (2) Atom feed templates.

Certain getText methods in the ActionSupport controller in Apache Roller before 5.0.2 allow remote attackers to execute arbitrary OGNL expressions via the first or second parameter, as demonstrated by the pageTitle parameter in the !getPageTitle sub-URL to roller-ui/login.rol, which uses a subclass of UIAction, aka "OGNL Injection."

Multiple cross-site request forgery (CSRF) vulnerabilities in the admin/editor console in Apache Roller before 5.0.1 allow remote attackers to hijack the authentication of admins or editors by leveraging the HTTP POST functionality.

Cross-site scripting (XSS) vulnerability in Apache Roller 2.3, 3.0, 3.1, and 4.0 allows remote attackers to inject arbitrary web script or HTML via the q parameter in a search action.
