CVE-2024-21988: CVE-2024-21988 SSH Cryptographic Implementation Vulnerability in StorageGRID (formerly StorageGRID Webscale)

MediumCVSS 5.3 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 21/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.23% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. Special conditions such as timing or configuration are required.
  • Fixed version: NetApp StorageGRID (formerly StorageGRID Webscale) 11.7.0.9, 11.8.0.5.

Low priority for now. Upgrade to NetApp StorageGRID (formerly StorageGRID Webscale) 11.7.0.9, 11.8.0.5 or later.

Root cause

The verifier takes the algorithm to verify with from the token’s own header. Untrusted data ends up deciding its own verification rule.
