SolarWinds Web Help Desk Hardcoded Credential Vulnerability

Noroxi assessment

Priority: Now (action score 94/100)

  • CISA has confirmed exploitation in the wild (Oct 15, 2024). Remediation deadline for US federal agencies: Nov 5, 2024.
  • A ready-made attack module is public (Metasploit, Nuclei); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 93.2% (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.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • According to the record, no fixed version is available yet.

Patch today or shut off access. Until a fix is released, restrict access to the affected component and follow the vendor's advisory.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Oct 15, 2024. That signals real attacks, not theory.

Remediation deadline for US federal agencies: Nov 5, 2024.

Weakness class (CWE)

CWE-798 · Use of Hard-coded Credentials

CVSS vector

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N

Root cause

For convenience in support or manufacturing, an account that is identical on every device is embedded in the software. Credentials learned from one device work on all of them.
