NONE Summary
In ActionView before versions 6.0.2.2 and 5.2.4.2, there is a possible XSS vulnerability in ActionView's JavaScript literal escape helpers. Views that use the `j` or `escape_javascript` methods may be susceptible to XSS attacks. The issue is fixed in versions 6.0.2.2 and 5.2.4.2.

Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Embedding Scripts in Non-Script Elements This attack is a form of Cross-Site Scripting (XSS) where malicious scripts are embedded in elements that are not expected to host scripts such as image tags (<img>), comments in XML documents (< !-CDATA->), etc. These tags may not be subject to the same input validation, output validation, and other content filtering and checking routines, so this can create an opportunity for an attacker to tunnel through the application's elements and launch a XSS attack through other elements. As with all remote attacks, it is important to differentiate the ability to launch an attack (such as probing an internal network for unpatched servers) and the ability of the remote attacker to collect and interpret the output of said attack.
- PHP Remote File Inclusion In this pattern the attacker is able to load and execute arbitrary code remotely available from the application. This is usually accomplished through an insecurely configured PHP runtime environment and an improperly sanitized "include" or "require" call, which the user can then control to point to any web-accessible file. This allows attackers to hijack the targeted application and force it to execute their own instructions.
