Noroxi assessment

Priority: Now (action score 97/100)

  • CISA has confirmed exploitation in the wild (Apr 8, 2025). Remediation deadline for US federal agencies: Apr 29, 2025.
  • A ready-made attack module is public (Metasploit, Nuclei); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 94.3% (FIRST EPSS); higher than 99.8% 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.
  • Fixed version: Gladinet CentreStack 16.4.10315.56368.

Patch today or shut off access. Upgrade to Gladinet CentreStack 16.4.10315.56368 or later.

Primary sources: NVD · CVE.org · CISA KEV · FIRST EPSS

Gladinet CentreStack through 16.1.10296.56315 (fixed in 16.4.10315.56368) has a deserialization vulnerability due to the CentreStack portal's hardcoded machineKey use, as exploited in the wild in March 2025. This enables threat actors (who know the machineKey) to serialize a payload for server-side deserialization to achieve remote code execution. NOTE: a CentreStack admin can manually delete the machineKey defined in portal\web.config.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Apr 8, 2025. That signals real attacks, not theory.

Remediation deadline for US federal agencies: Apr 29, 2025.
