Privilege Escalation vulnerability in Apache Software Foundation Apache Sling. Any content author is able to create i18n dictionaries in the repository in a location the author has write access to. As these translations are used across the whole product, it allows an author to change any text or dialog in the product. For example an attacker might fool someone by changing the text on a delete button to "Info". This issue affects the i18n module of Apache Sling up to version 2.5.18. Version 2.6.2 and higher limit by default i18m dictionaries to certain paths in the repository (/libs and /apps).

Users of the module are advised to update to version 2.6.2 or higher, check the configuration for resource loading and then adjust the access permissions for the configured path accordingly.

An improper neutralization of input during web page generation ('Cross-site Scripting') [CWE-79] vulnerability in Sling App CMS version 1.1.4 and prior may allow an authenticated remote attacker to perform a reflected cross-site scripting (XSS) attack in multiple features.

Upgrade to Apache Sling App CMS >= 1.1.6

An improper neutralization of input during web page generation ('Cross-site Scripting') [CWE-79] vulnerability in Sling App CMS version 1.1.2 and prior may allow an authenticated remote attacker to perform a reflected cross-site scripting (XSS) attack in the site group feature.

Upgrade to Apache Sling App CMS >= 1.1.4

Apache Sling Commons Log <= 5.4.0 and Apache Sling API <= 2.25.0 are vulnerable to log injection. The ability to forge logs may allow an attacker to cover tracks by injecting fake logs and potentially corrupt log files.

Multiple cross-site scripting (XSS) vulnerabilities in Apache Sling API before 2.2.2 and Apache Sling Servlets Post before 2.1.2 allow remote attackers to inject arbitrary web script or HTML via the URI, related to (1) org/apache/sling/api/servlets/HtmlResponse and (2) org/apache/sling/servlets/post/HtmlResponse.

Open redirect vulnerability in the AbstractAuthenticationFormServlet in the Auth Core (org.apache.sling.auth.core) bundle before 1.1.4 in Apache Sling allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a URL in the resource parameter, related to "a custom login form and XSS."

The @CopyFrom operation in the POST servlet in the org.apache.sling.servlets.post bundle before 2.1.2 in Apache Sling does not prevent attempts to copy an ancestor node to a descendant node, which allows remote attackers to cause a denial of service (infinite loop) via a crafted HTTP request.
