CVE-2024-30261: Undici's fetch with integrity option is too lax when algorithm is specified but hash value is in incorrect

Noroxi assessment

Priority: Monitor (action score 14/100)

  • 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: 0.80% (FIRST EPSS); higher than 56.5% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: Azure Linux 3.0 ARM 20.14.0-1; Azure Linux 3.0 x64 20.14.0-1; CBL Mariner 2.0 ARM 18.20.2-1.

Low priority for now. Upgrade to Azure Linux 3.0 ARM 20.14.0-1; Azure Linux 3.0 x64 20.14.0-1; CBL Mariner 2.0 ARM 18.20.2-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Undici is an HTTP/1.1 client, written from scratch for Node.js. An attacker can alter the `integrity` option passed to `fetch()`, allowing `fetch()` to accept requests as valid even if they have been tampered. This vulnerability was patched in version(s) 5.28.4 and 6.11.1.
