This affects the package object-path before 0.11.6. A type confusion vulnerability can lead to a bypass of CVE-2020-15256 when the path components used in the path parameter are arrays. In particular, the condition currentPath === '__proto__' returns false if currentPath is ['__proto__']. This is because the === operator returns always false when the type of the operands is different.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

The remote Ubuntu 18.04 LTS / 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5967-1 advisory.

    It was discovered that the set() method in object-path could be corrupted as a result of prototype     pollution by sending a message to the parent process. An attacker could use this issue to cause object-     path to crash. (CVE-2020-15256, CVE-2021-23434, CVE-2021-3805)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Debian 10 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-3291 advisory.

    Package        : node-object-path     Version        : 0.11.4-2+deb10u2     CVE ID         : CVE-2021-3805 CVE-2021-23434

    It was discovered that node-object-path, a Node.js module to access deep     object properties using dot-separated paths, was vulnerable to prototype     pollution.

    CVE-2021-3805

        Prototype pollution vulnerability in the `del()`, `empty()`,         `push()` and `insert()` functions when using the inherited props         mode (e.g.  when a new `object-path` instance is created with the         `includeInheritedProps` option set to `true` or when using the         `withInheritedProps` default instance).

    CVE-2021-23434

        A type confusion vulnerability can lead to a bypass of the         CVE-2020-15256 fix when the path components used in the path         parameter are arrays, because the === operator returns always false         when the type of the operands is different.

    For Debian 10 buster, these problems have been fixed in version     0.11.4-2+deb10u2.

    We recommend that you upgrade your node-object-path packages.
