SB2023051950 - Multiple vulnerabilities in IBM InfoSphere Information Server

Description

This security bulletin contains information about 6 secuirty vulnerabilities.

1) Path traversal (CVE-ID: CVE-2019-16777)

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.

2) Improper input validation (CVE-ID: CVE-2019-16776)

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.

3) Inclusion of Sensitive Information in Log Files (CVE-ID: CVE-2020-15095)

The vulnerability allows a local user to gain access to sensitive information.

The vulnerability exists due to NPM Cli stores sensitive information into log files and supports URLs like "://[[:]@][:][:][/]". A local user can redirect output of a log file to an external URL.

4) Symlink following (CVE-ID: CVE-2019-16775)

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.

5) Information disclosure (CVE-ID: CVE-2022-29244)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to npm pack ignores root-level .gitignore and .npmignore file exclusion directives when run in a workspace or with a workspace flag (ie. `--workspaces`, `--workspace=`). Anyone who has run `npm pack` or `npm publish` inside a workspace, may be affected and have published files into the npm registry they did not intend to include.

6) Incorrect Regular Expression (CVE-ID: CVE-2020-7754)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient input validation when processing regular expressions. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.
