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 remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by a vulnerability that has been acknowledged by the vendor but will not be patched.

  - object-path: Type confusion vulnerability can lead to a bypass of CVE-2020-15256 (CVE-2021-23434)

Note that Nessus has not tested for this issue but has instead relied on the package manager's report that the package is installed.

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.

  - A prototype pollution vulnerability has been found in `object-path` <= 0.11.4 affecting the `set()`     method. The vulnerability is limited to the `includeInheritedProps` mode (if version >= 0.11.0 is used),     which has to be explicitly enabled by creating a new instance of `object-path` and setting the option     `includeInheritedProps: true`, or by using the default `withInheritedProps` instance. The default     operating mode is not affected by the vulnerability if version >= 0.11.0 is used. Any usage of `set()` in     versions < 0.11.0 is vulnerable. The issue is fixed in object-path version 0.11.5 As a workaround, don't     use the `includeInheritedProps: true` options or the `withInheritedProps` instance if using a version >=     0.11.0. (CVE-2020-15256)
