# e107 CMS: reflected XSS in search.php author parameter

e107 CMS before 2.3.13 reflects the author GET parameter in search.php into an HTML input tag without escaping. An attacker who gets a victim to open a crafted link can run JavaScript in the victim's browser session.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed e107 version in the site's version file or admin dashboard; versions below `2.3.13` are affected.
- Request `search.php` with an `author` parameter containing HTML-breaking characters and see whether it is echoed unescaped (unknown whether sources give an exact test).

## Fix

- Upgrade e107 to `2.3.13` or later.
- Until upgraded, unknown whether a WAF rule or parameter filtering is an adequate workaround per the sources.

## From the sources

e107 CMS before 2.3.13 contains a reflected cross-site scripting vulnerability that allows unauthenticated attackers to inject malicious HTML by manipulating the author GET parameter in search.php, which is parsed with parse_str() and concatenated unescaped into a rendered input tag via the form handler's 'other' option key. Attackers can craft a single GET request containing a crafted author parameter to break out of the HTML input tag and inject an img element with an onerror handler, executing arbitrary JavaScript in the victim's browser session.
