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.
