Description

This security bulletin contains information about 7 vulnerabilities.


1) Covert Timing Channel (CVE-ID: CVE-2023-46809)

CWE-ID: CWE-385 - Covert Timing Channel

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform Marvin attack.

The vulnerability exists due to a covert timing channel in the privateDecrypt() API of the crypto library. A remote attacker can perform a covert timing side-channel during PKCS#1 v1.5 padding error handling and decrypt captured RSA ciphertexts or forge signatures, especially in scenarios involving API endpoints processing Json Web Encryption messages.


2) Input validation error (CVE-ID: CVE-2024-22019)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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 processing HTTP requests with chunked encoding. A remote attacker can send specially crafted HTTP request to the server and perform a denial of service (DoS) attack.


3) Improper handling of exceptional conditions (CVE-ID: CVE-2024-21892)

CWE-ID: CWE-755 - Improper Handling of Exceptional Conditions

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to the way certain environment variables are handled by Node.js on Linux. A local user can use a specially crafted environment variable to escalate privileges on the system.


4) Path traversal (CVE-ID: CVE-2024-21896)

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

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


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

The vulnerability exists due to input validation error when processing directory traversal sequences in Buffer.prototype.utf8Write. A remote attacker can send a specially crafted HTTP request and read arbitrary files on the system.


5) Path traversal (CVE-ID: CVE-2024-21891)

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

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


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

The vulnerability exists due to input validation error when processing directory traversal sequences. A remote attacker can send a specially crafted HTTP request and read arbitrary files on the system.


6) Inconsistency between implementation and documented design (CVE-ID: CVE-2024-21890)

CWE-ID: CWE-1068 - Inconsistency Between Implementation and Documented Design

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


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

The vulnerability exists due to improper handling of wildcards in --allow-fs-read and --allow-fs-write. A remote attacker can gain access to sensitive information.


7) Improper Privilege Management (CVE-ID: CVE-2024-22017)

CWE-ID: CWE-269 - Improper Privilege Management

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:U/U:Clear


The vulnerability allows a local user to escalate privileges.

The vulnerability exists due to setuid() does not affect libuv's internal io_uring operations if initialized before the call to setuid(). A local user can escalate privileges on the system.
