CVE-2025-32756: A stack-based buffer overflow vulnerability [CWE-121] vulnerability in Fortinet FortiCamera 2.1.0 through 2.1.3, FortiCamera 2.0 all version

Noroxi assessment

Priority: This week (action score 78/100)

  • CISA has confirmed exploitation in the wild (May 14, 2025). Remediation deadline for US federal agencies: Jun 4, 2025.
  • Probability of exploitation in the next 30 days: 30.9% (FIRST EPSS); higher than 98.2% 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.

Don’t wait for the next maintenance window. Until a fix is released, restrict access to the affected component and follow the vendor's advisory.
