CVE-2019-11447

This flaw is in the “upload an avatar/profile image” feature. An attacker can send a specially crafted image file so the system accepts it when it shouldn’t, and that crafted file can be used to run code on the server.

Think of it like a building that has a door meant for harmless packages, but the door-check can be fooled with a fake label—so the attacker brings in something dangerous.

This matters if you run CutePHP CuteNews 2.1.2 on your site. It’s relevant to you if your site has the avatar/profile upload feature enabled, since that’s the pathway attackers use.

There’s a risk when an attacker can reach that upload functionality (typically via the web app), and the environment allows submitting avatar uploads (for example, by users who can upload avatars).

This is an AMBER issue because a public exploit exists and attackers can leverage it through the avatar upload process to get code execution on the server. That means real-world targeting is plausible rather than purely theoretical.

Since no fix details are available here, treat it as a priority to verify your version and immediately reduce exposure (especially by restricting avatar uploads) while planning an upgrade.

Confirm exposure

1. Verify the exact CuteNews version installed on your system (confirm it is 2.1.2).
2. Identify whether your site exposes the avatar/profile image upload feature (the profile area upload that uses the avatar_file field).
3. Determine whether uploads are available to the public, to logged-in users, or only to certain roles.

Check for a fix

• In the provided findings, no fix/patch information is available, so you should ask your vendor/maintainer for a fixed release for CuteNews 2.1.2 (or determine whether an upgrade to a newer CuteNews version includes the fix).

Remediation / upgrade

1. Plan an upgrade to a CuteNews release that includes the fix for CVE-2019-11447.
2. If you can’t immediately upgrade, schedule a short-term mitigation (see below) that blocks the vulnerable behavior.

Temporary workaround (if patching is delayed)

• Disable or restrict avatar/profile image uploads until you can upgrade.
• If you can’t fully disable it, limit who can upload avatars (tighten roles/permissions) and add strict upload controls if your stack supports it (e.g., rejecting unexpected content types and enforcing server-side validation).

Monitoring while you remediate

• Watch for suspicious upload attempts to the avatar upload endpoint.
• Look for follow-on indicators such as unexpected new files in web-accessible locations, abnormal changes in timestamps for uploaded content, or unexpected server errors after an upload.

Timeline

• No CISA KEV listing was found in the provided findings, so there is no KEV-driven deadline here; however, given public exploit availability, prioritize this within your normal urgent patch window.

Overview and severity

• CVE-2019-11447 in CutePHP CuteNews 2.1.2 has a high-risk profile (code execution potential) based on the described upload bypass.

Weakness and mechanism

• The underlying weakness is consistent with CWE-434 (unrestricted file upload / bypass of intended file handling controls).
• Mechanism: the avatar upload process in the profile area (using avatar_file) is reachable via index.php?mod=main&opt=personal. The issue is described as a failure to effectively control image size (and related validation), where the file header content can be altered to bypass checks. Crafted headers (e.g., a GIF header) can be used to trick validation, potentially leading to code execution.

Exploitation status

• A public exploit is available (3 known). The findings do not list it in CISA KEV.

Fix availability

• The findings state no fix/patch information is available, so you should not assume an in-place patch exists for 2.1.2; upgrading to a fixed release is the likely path.

Predictive likelihood

• EPSS is provided as a prediction only; no KEV confirmation is present in the findings to override it.
