CVE-2018-18325· NVD / CVE Program· CNA mitre

DNN (aka DotNetNuke) 9.2 through 9.2.2 uses a weak encryption algorithm to protect input parameters.

Noroxi assessment

Priority: Now (action score 82/100)

  • CISA has confirmed exploitation in the wild (Nov 3, 2021). Remediation deadline for US federal agencies: May 3, 2022.
  • A ready-made attack module is public (Metasploit, Nuclei); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 73.8% (FIRST EPSS); higher than 99.4% 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.
  • Fixed version: DotNetNuke.Core (NuGet) 9.3.0.

Patch today or shut off access. Upgrade to DotNetNuke.Core (NuGet) 9.3.0 or later.

Vulnrichment: CISA's decision-tree inputs.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Nov 3, 2021. That signals real attacks, not theory.

Remediation deadline for government agencies: May 3, 2022.
