CVE-2020-8174: napi_get_value_string_*() allows various kinds of memory corruption in node < 10.21.0, 12.18.0, and < 14.4.0.

Noroxi assessment

Priority: Monitor (action score 34/100)

  • 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: 7.6% (FIRST EPSS); higher than 94.5% 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. Special conditions such as timing or configuration are required.
  • Fixed version: nodejs-nodemon (AlmaLinux:8) 1.18.3-1.module_el8.3.0+2023+d2377ea3, 1.18.3-1.module_el8.3.0+2047+b07ac28e; nodejs-packaging (AlmaLinux:8) 17-3.module_el8.4.0+2224+b07ac28e, 17-3.module_el8.3.0+2023+d2377ea3, 17-3.module_el8.4.0+2521+c668cc9f; nodejs (Alpine:v3.11) 12.20.1-r0.
  • Mentioned 3 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to nodejs-nodemon (AlmaLinux:8) 1.18.3-1.module_el8.3.0+2023+d2377ea3, 1.18.3-1.module_el8.3.0+2047+b07ac28e; nodejs-packaging (AlmaLinux:8) 17-3.module_el8.4.0+2224+b07ac28e, 17-3.module_el8.3.0+2023+d2377ea3, 17-3.module_el8.4.0+2521+c668cc9f; nodejs (Alpine:v3.11) 12.20.1-r0 or later.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
