EUVDB-ID: #VU86724

Risk: Medium

CVSSv4.0: 2.7 [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]

CVE-ID: CVE-2023-46809

CWE-ID: CWE-385 - Covert Timing Channel

Exploit availability: No

Description

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.

Mitigation

Install update from vendor's website.

5) Server-Side Request Forgery (SSRF)

EUVDB-ID: #VU86707

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:L/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2024-24806

CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)

Exploit availability: No

Description

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.

Mitigation

Install update from vendor's website.
