Hawk is an HTTP authentication scheme providing mechanisms for making authenticated HTTP requests with partial cryptographic verification of the request and response, covering the HTTP method, request URI, host, and optionally the request payload. Hawk used a regular expression to parse `Host` HTTP header (`Hawk.utils.parseHost()`), which was subject to regular expression DoS attack - meaning each added character in the attacker's input increases the computation time exponentially. `parseHost()` was patched in `9.0.1` to use built-in `URL` class to parse hostname instead. `Hawk.authenticate()` accepts `options` argument. If that contains `host` and `port`, those would be used instead of a call to `utils.parseHost()`.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-016758 advisory.

The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-6116-1 advisory.

    It was discovered that hawk incorrectly handled certain inputs. If a user or an automated system were     tricked into opening a specially crafted input file, a remote attacker could possibly use this issue to     cause a denial of service.

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

    Package        : node-hawk     Version        : 6.0.1+dfsg-1+deb10u1     CVE IDs        : CVE-2022-29167

    It was discovered that there was an issue in Hawk, an HTTP     authentication scheme. Hawk used a regular expression to parse `Host`     HTTP headers which was subject to regular expression DoS attack. Each     added character in the attacker's input increased the computation     time exponentially.

    For Debian 10 buster, this problem has been fixed in version     6.0.1+dfsg-1+deb10u1.

    We recommend that you upgrade your node-hawk packages.
