Description

A weakness has been identified in yungifez Skuul School Management System up to 2.6.5. This vulnerability affects unknown code of the file /dashboard/schools/1/edit of the component SVG File Handler. This manipulation causes cross site scripting. The attack is possible to be carried out remotely. The exploit has been made available to the public and could be exploited. The vendor was contacted early about this disclosure but did not respond in any way.

Detection & mitigation playbook

Vendor / appliance
  1. Detect

    Inventory every yungifez skuul deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for exploitation at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.

  2. Remediation status

    No patch has shipped for CVE-2025-13784 yet — track the yungifez skuul advisory for a fixed release and apply the workarounds below in the meantime.

  3. Mitigate without a patch

    Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.

  4. How O3 protects you

    O3 detects and blocks CVE-2025-13784 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.

Tailored to CVE-2025-13784. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
