Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Incorrect Regular Expression

EUVDB-ID: #VU55315

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2021-23343

CWE-ID: CWE-185 - Incorrect Regular Expression

Exploit availability: No

Description

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

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

Mitigation

Update the affected package nodejs8 to the latest version.

2) Absolute Path Traversal

EUVDB-ID: #VU58206

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2021-32803

CWE-ID: CWE-36 - Absolute Path Traversal

Exploit availability: No

Description

The vulnerability allows a remote attacker to overwrite arbitrary files on the system.

The vulnerability exists due to a logic issue when extracting tar files that contained both a directory and a symlink with the same name as the directory. This order of operations resulted in the directory being created and added to the node-tar directory cache. When a directory is present in the directory cache, subsequent calls to mkdir for that directory are skipped. However, this is also where node-tar checks for symlinks occur.

By first creating a directory, and then replacing that directory with a symlink, it was thus possible to bypass node-tar symlink checks on directories, essentially allowing an untrusted tar file to symlink into an arbitrary location and subsequently extracting arbitrary files into that location, thus allowing arbitrary file creation and overwrite.

Mitigation

Update the affected package nodejs8 to the latest version.

3) Absolute Path Traversal

EUVDB-ID: #VU58205

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2021-32804

CWE-ID: CWE-36 - Absolute Path Traversal

Exploit availability: No

Description

The vulnerability allows a remote attacker to overwrite arbitrary files on the system.

The vulnerability exists due to a logic issue when file paths contained repeated path roots such as ////home/user/.bashrc. node-tar would only strip a single path root from such paths. When given an absolute file path with repeating path roots, the resulting path (e.g. ///home/user/.bashrc) would still resolve to an absolute path, thus allowing arbitrary file creation and overwrite.

Mitigation

Update the affected package nodejs8 to the latest version.

4) Input validation error

EUVDB-ID: #VU57967

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2021-3807

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

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

The vulnerability exists due to insufficient validation of user-supplied input when matching crafted invalid ANSI escape codes in ansi-regex. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.

Mitigation

Update the affected package nodejs8 to the latest version.
