Description

This security bulletin contains information about 6 secuirty vulnerabilities.


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

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

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.


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

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.


4) Input validation error (CVE-ID: CVE-2024-22025)

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 handling brotli decoding. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.


5) Information disclosure (CVE-ID: CVE-2024-24758)

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

The vulnerability exists due to the application does not clear the Proxy-Authentication HTTP header when handling cross-origin redirects. A remote attacker can gain access to sensitive information.


6) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2024-24806)

The disclosed vulnerability allows a remote attacker to perform SSRF attacks.

The vulnerability exists due to insufficient validation of user-supplied input when handling hostnames longer than 256 characters within the uv_getaddrinfo() function in src/unix/getaddrinfo.c and its windows counterpart src/win/getaddrinfo.c. A remote attacker can pass a specially crafted hostname to the application, which can be resolved to an attacker controlled IP address and initiate unauthorized requests to arbitrary systems.

Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.
