Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Actionview, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

There is a possible XSS vulnerability in Action View tag helpers. Passing untrusted input as hash keys can lead to a possible XSS vulnerability. This vulnerability has been assigned the CVE identifier CVE-2022-27777. Versions Affected: ALL Not affected: NONE Fixed Versions: 7.0.2.4, 6.1.5.1, 6.0.4.8, 5.2.7.1 ## Impact If untrusted data is passed as the hash key for tag attributes, there is a possibility that the untrusted data may not be properly escaped which can lead to an XSS vulnerability. Impacted code will look something like this: ``` check_box_tag('thename', 'thevalue', false, aria: { malicious_input => 'thevalueofaria' }) ``` Where the "malicious_input" variable contains untrusted data. All users running an affected release should either upgrade or use one of the workarounds immediately. ## Releases The FIXED releases are available at the normal locations. ## Workarounds Escape the untrusted data before using it as a key for tag helper methods.
