4) Incorrect Regular Expression

EUVDB-ID: #VU92406

Risk: Medium

CVSSv3.1: 6.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:T/RC:C]

CVE-ID: CVE-2024-4067

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 occurs in `micromatch.braces()` in `index.js` because the pattern `.*` will greedily match anything. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.

Mitigation

Install update from vendor's website.

6) Uncontrolled Memory Allocation

EUVDB-ID: #VU92405

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-2024-4068

CWE-ID: CWE-789 - Uncontrolled Memory Allocation

Exploit availability: No

Description

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

The vulnerability exists due to NPM package `braces` fails to limit the number of characters it can handle, which could lead to Memory Exhaustion. A remote attacker can send "imbalanced braces" as input, the parsing will enter a loop, which will cause the program to start allocating heap memory without freeing it at any moment of the loop. Eventually, the JavaScript heap limit is reached, and the program will crash.

Mitigation

Install update from vendor's website.
