CVE-2024-21488:
JavaScript vulnerability analysis and mitigation
Overview
CVE-2024-21488 affects versions of the network package before 0.7.0, which contains an Arbitrary Command Injection vulnerability. The vulnerability exists in the macaddressfor function of the package, where unsanitized user input can lead to arbitrary command execution on the operating system where the package is running (Snyk Advisory, NVD). The vulnerability was discovered and disclosed in January 2024.
Technical details
The vulnerability stems from the improper use of the childprocess exec function without input sanitization in the macaddress_for function. This aligns with CWE-77 (Improper Neutralization of Special Elements used in a Command). The CVSS v3.1 scores vary between sources, with NVD rating it as 9.8 CRITICAL (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) and Snyk rating it as 7.3 HIGH (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L) (NVD).
Impact
If exploited, this vulnerability allows attackers to execute arbitrary commands on the operating system where the package is being run. The impact includes potential unauthorized access to system resources, data manipulation, and system compromise (Snyk Advisory).
Mitigation and workarounds
The vulnerability has been patched in version 0.7.0 of the network package. The fix includes input validation for the nic_name parameter. Users should upgrade to version 0.7.0 or later. If upgrading is not immediately possible, it is recommended to use execFile or execFileSync instead of exec, and implement proper input sanitization to prevent shell metacharacter injection (GitHub Commits).
