Multiple vulnerabilities in IBM VM Recovery Manager DR

1) Symlink following

EUVDB-ID: #VU23888

Risk: Low

CVSSv3.1: 3.7 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-16775

CWE-ID: CWE-61 - UNIX Symbolic Link (Symlink) Following

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform directory traversal attacks.

Versions of the npm CLI prior to 6.13.3 are vulnerable to a symlink reference outside of node_modules. It is possible for packages to create symlinks to files outside of the node_modules folder through the bin field upon installation. A properly constructed entry in the package.json bin field would allow a package publisher to create a symlink pointing to arbitrary files on a user’s system when the package is installed. Only files accessible by the user running the npm install are affected.

Mitigation

Install update from vendor's website.

2) Improper input validation

EUVDB-ID: #VU25078

Risk: High

CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-16776

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote authenticated user to read and manipulate data.

The vulnerability exists due to improper input validation within the JavaScript (Node.js) component in Oracle GraalVM Enterprise Edition. A remote authenticated user can exploit this vulnerability to read and manipulate data.

Mitigation

3) Path traversal

EUVDB-ID: #VU23880

Risk: Low

CVSSv3.1: 3.7 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-16777

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences. The software fails to prevent existing globally-installed binaries to be overwritten by other package installations. For example, if a package was installed globally and created a serve binary, any subsequent installs of packages that also create a serve binary would overwrite the first binary. This only affects files in /usr/local/bin

A remote attacker can overwrite arbitrary files on the system.

Mitigation

Install update from vendor's website.
