CVE-2026-104935: Authentication bypass by spoofing in ICS before version 25.1.3.0 allows a remote unauthenticated attacker to execute arbitrary commands.
Noroxi assessment
Priority: Now (action score 91/100)
- CISA has confirmed exploitation in the wild (Oct 13, 2026). Remediation deadline for US federal agencies: Oct 16, 2026.
- A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
- Probability of exploitation in the next 30 days: 88.9% (FIRST EPSS); higher than 99.7% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- According to CISA the attack is automatable: targets can be found by mass scanning.
- According to the record, no fixed version is available yet.
- Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Patch today or shut off access. Until a fix is released, restrict access to the affected component and follow the vendor's advisory.
