This manipulation of the argument f_file/f_prefix causes cross site scripting. The attack may be initiated remotely. The exploit has been published and may be used. Upgrading to version 109.4 is able to resolve this issue. Patch name: 8a3946bd0a54bfb72a4d57179fcd253f2c550cd7. The affected component should be upgraded. The vendor was informed early about this issue. They classify it as a "Self-XSS". They deployed a countermeasure: "Nevertheless, we consider this a violation of secure coding standards. The lack of filtering via `htmlspecialchars()` has already been fixed in the latest patch to prevent incorrect data display."
A cross-site scripting (XSS) vulnerability has been identified in MaxSite CMS versions prior to 109.3, specifically within the down_count plugin. The issue arises from improper sanitization of the f_file and f_prefix parameters, allowing attackers to inject malicious scripts. This vulnerability can be exploited remotely and has been publicly disclosed.
Users are advised to upgrade to MaxSite CMS version 109.4, which addresses this vulnerability by implementing proper input sanitization. The update can be downloaded from the MaxSite CMS GitHub repository.
