The shell-quote package before 1.7.3 for Node.js allows command injection. An attacker can inject unescaped shell metacharacters through a regex designed to support Windows drive letters. If the output of this package is passed to a real shell as a quoted argument to a command with exec(), an attacker can inject arbitrary commands. This is because the Windows drive letter regex character class is {A-z] instead of the correct {A-Za-z]. Several shell metacharacters exist in the space between capital letter Z and lower case letter a, such as the backtick character.

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

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote SUSE Linux SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:3761-1 advisory.

  - drools <=7.59.x is affected by an XML External Entity (XXE) vulnerability in KieModuleMarshaller.java. The     Validator class is not used correctly, resulting in the XXE injection vulnerability. (CVE-2021-41411)

  - In Async before 2.6.4 and 3.x before 3.2.2, a malicious user can obtain privileges via the mapValues()     method, aka lib/internal/iterator.js createObjectIterator prototype pollution. (CVE-2021-43138)

  - Improper Authorization in GitHub repository cobbler/cobbler prior to 3.3.2. (CVE-2022-0860)

  - moment is a JavaScript date library for parsing, validating, manipulating, and formatting dates. Affected     versions of moment were found to use an inefficient parsing algorithm. Specifically using string-to-date     parsing in moment (more specifically rfc2822 parsing, which is tried by default) has quadratic (N^2)     complexity on specific inputs. Users may notice a noticeable slowdown is observed with inputs above 10k     characters. Users who pass user-provided strings without sanity length checks to moment constructor are     vulnerable to (Re)DoS attacks. The problem is patched in 2.29.4, the patch can be applied to all affected     versions with minimal tweaking. Users are advised to upgrade. Users unable to upgrade should consider     limiting date lengths accepted from user input. (CVE-2022-31129)

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