CVE-2020-15123: Codecov Command Injection Vulnerability
MODERATECVE-2020-15123 is a MODERATE (CVSS 9.3) command injection vulnerability (CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')) affecting Codecov libraries in the npm ecosystem. The issue involves command injection in codecov (npm package). Remediation is available by upgrading affected packages to version 3.7.1.

Security Impact
CVSS: 9.3
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N).
How to Fix CVE-2020-15123
To remediate this vulnerability, upgrade all affected Codecov dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
npm install codecov@3.7.1Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls codecovHow to Check if You Are Affected
To determine whether your Node.js application is affected by CVE-2020-15123, inspect your project dependencies using npm:
npm ls codecovAnalyze the terminal output to locate any version of Codecov in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.7.1), your application is affected.
Note: The npm ls codecov command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'), where the product constructs all or part of an os command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended os command when it is sent to a downstream component. In Codecov, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"details" : "### Impact\n\nThe `upload` method has a command injection vulnerability. Clients of the `codecov-node` library are unlikely to be aware of this, so they might unwittingly write code that contains a vulnerability.\n\nA similar CVE was issued: [CVE-2020-7597](https://github.com/advisories/GHSA-5q88-cjfq-g2mh), but the fix was incomplete. It only blocked `&`, and command injection is still possible using backticks instead to bypass the sanitizer.\n\nWe have written a [CodeQL](https://codeql.com) query, which automatically detects this vulnerability. You can see the results of the query on the `codecov-node` project [here](https://lgtm.com/query/7714424068617023832/).\n\n\n### Patches\nThis has been patched in version 3.7.1\n\n### Workarounds\n\nNone, however, the attack surface is low in this case. Particularly in the standard use of codecov, where the module is used directly in a build pipeline, not built against as a library in another application that may supply malicious input and perform command injection. \n\n### References\n* [CVE-2020-7597](https://github.com/advisories/GHSA-5q88-cjfq-g2mh)\n\n### For more information\nIf you have any questions or comments about this advisory:\n* Contact us via our [Security Email](mailto:security@codecov.io)",
