CVE-2025-6563 is a cross-site scripting vulnerability in the Hotspot component of MikroTik RouterOS affecting versions prior to 7.19.2. The issue arises because the dst parameter can be supplied with a javascript: URI, which is then processed in a way that allows script execution in the victim’s browser. Exploitation requires luring a victim to a crafted Hotspot URL; when the victim follows the link and logs in, the injected JavaScript executes. The available description also notes that the Hotspot login POST request can be transformed into a GET request, enabling a single crafted URL to both log the victim into an attacker-controlled account and trigger the XSS payload automatically.

If you can’t patch tonight, do this now.
dst= or javascript: patterns. Where feasible, deploy filtering or rewriting at reverse proxies/WAFs to block javascript: URI schemes and unexpected GET-based login flows. User awareness measures can also reduce risk by discouraging use of unsolicited Hotspot login links. These are compensating controls only and do not replace upgrading to a fixed RouterOS release.Patch, then assume compromise.
javascript: are not accepted in redirect-related parameters such as dst.No valid public exploits. Mallory filtered out 2 candidates as fakes, detection scripts, or README-only repos.
