libuv is a multi-platform support library with a focus on asynchronous I/O. The
uv_getaddrinfofunction insrc/unix/getaddrinfo.c(and its windows counterpartsrc/win/getaddrinfo.c), truncates hostnames to 256 characters before callinggetaddrinfo. This behavior can be exploited to create addresses like0x00007f000001, which are considered valid bygetaddrinfoand could allow an attacker to craft payloads that resolve to unintended IP addresses, bypassing developer checks. The vulnerability arises due to how thehostname_asciivariable (with a length of 256 bytes) is handled inuv_getaddrinfoand subsequently inuv__idna_toascii. When the hostname exceeds 256 characters, it gets truncated without a terminating null byte. As a result attackers may be able to access internal APIs or for websites (similar to MySpace) that allows users to haveusername.example.compages. Internal services that crawl or cache these user pages can be exposed to SSRF attacks if a malicious user chooses a long vulnerable username. This issue has been addressed in release version 1.48.0. Users are advised to upgrade. There are no known workarounds for this vulnerability. - References
