CVE-2019-16775· NVD / CVE Program· CNA GitHub_M

Unauthorized File Access in npm CLI before before version 6.13.3

Noroxi assessment

Priority: Monitor (action score 27/100)

  • 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: 3.3% (FIRST EPSS); higher than 88.4% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: nodejs-nodemon (AlmaLinux:8) 1.18.3-1.module_el8.3.0+2047+b07ac28e, 1.18.3-1.module_el8.3.0+2023+d2377ea3; nodejs-packaging (AlmaLinux:8) 17-3.module_el8.3.0+2023+d2377ea3, 17-3.module_el8.4.0+2521+c668cc9f, 17-3.module_el8.4.0+2224+b07ac28e; npm (Debian:12) 6.13.4+ds-2.
  • Mentioned 1 time 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+2047+b07ac28e, 1.18.3-1.module_el8.3.0+2023+d2377ea3; nodejs-packaging (AlmaLinux:8) 17-3.module_el8.3.0+2023+d2377ea3, 17-3.module_el8.4.0+2521+c668cc9f, 17-3.module_el8.4.0+2224+b07ac28e; npm (Debian:12) 6.13.4+ds-2 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

Versions of the npm CLI prior to 6.13.3 are vulnerable to an Arbitrary File Write. It is possible for packages to create symlinks to files outside of thenode_modules folder through the bin field upon installation. A properly constructed entry in the package.json bin field would allow a package publisher to create a symlink pointing to arbitrary files on a user's system when the package is installed. This behavior is still possible through install scripts. This vulnerability bypasses a user using the --ignore-scripts install option.
