CVE-2025-11635 — Tomofun Furbo 360 File Upload resource consumption

A weakness has been identified in Tomofun Furbo 360 up to FB0035_FW_036. This vulnerability affects unknown code of the component File Upload. This manipulation causes resource consumption. Remote exploitation of the attack is possible. The vendor was contacted early about this disclosure but did not respond in any way.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.5% (30-day exploitation probability)+6
  • Technical severity (medium)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Furbo Furbo 360 Dog Camera Firmware, Tomofun Furbo 360).
  2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  3. Search available logs for exploit probes matching the vulnerability class (denial of service), errors and authentication anomalies.

What should defenders know first?

CVE-2025-11635 is "Tomofun Furbo 360 File Upload resource consumption", rated Medium. It affects Furbo 360 Dog Camera Firmware (Furbo); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 6.5 describes technical severity. EPSS 0.45% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
