This security bulletin contains information about 4 vulnerabilities.

1) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU79332

Risk: Medium

CVSSv3.1: 6.4 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-32002

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to improperly imposed security restrictions for the Module._load() method. A remote attacker can bypass the policy mechanism and include modules outside of the policy.json definition for a given module.

Mitigation

Install update from vendor's website.

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Incorrect Regular Expression

EUVDB-ID: #VU78932

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-25883

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 when processing regular expressions. A remote attacker can pass specially crafted data to the application via the new Range function and perform regular expression denial of service (ReDos) attack.

Mitigation

Install updates from vendor's website.

3) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU79335

Risk: Medium

CVSSv3.1: 6.4 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-32559

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to usage of deprecated API process.binding(). A remote attacker can bypass the policy mechanism by requiring internal modules and eventually take advantage of process.binding('spawn_sync') run arbitrary code, outside of the limits defined in a policy.json file.

Mitigation

Install update from vendor's website.
