The `uv_getaddrinfo` function in `src/unix/getaddrinfo.c` (and its windows counterpart `src/win/getaddrinfo.c`), truncates hostnames to 256 characters before calling `getaddrinfo`. This behavior can be exploited to create addresses like `0x00007f000001`, which are considered valid by `getaddrinfo` and could allow an attacker to craft payloads that resolve to unintended IP addresses, bypassing developer checks. The vulnerability arises due to how the `hostname_ascii` variable (with a length of 256 bytes) is handled in `uv_getaddrinfo` and subsequently in `uv__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 have `username.example.com` pages. 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." } ], "source": { "advisory": "GHSA-f74f-cvh7-c6q6", "discovery": "UNKNOWN" } }, "adp": [ { "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-09-02T17:08:43.903Z" }, "title": "CVE Program Container", "references": [ { "name": "https://github.com/libuv/libuv/security/advisories/GHSA-f74f-cvh7-c6q6", "tags": [ "x_refsource_CONFIRM", "x_transferred" ], "url": "https://github.com/libuv/libuv/security/advisories/GHSA-f74f-cvh7-c6q6" }, { "name": "https://github.com/libuv/libuv/commit/0f2d7e784a256b54b2385043438848047bc2a629", "tags": [ "x_refsource_MISC", "x_transferred" ], "url": "https://github.com/libuv/libuv/commit/0f2d7e784a256b54b2385043438848047bc2a629" }, { "name": "https://github.com/libuv/libuv/commit/3530bcc30350d4a6ccf35d2f7b33e23292b9de70", "tags": [ "x_refsource_MISC", "x_transferred" ], "url": "https://github.com/libuv/libuv/commit/3530bcc30350d4a6ccf35d2f7b33e23292b9de70" }, { "name": "https://github.com/libuv/libuv/commit/c858a147643de38a09dd4164758ae5b685f2b488", "tags": [ "x_refsource_MISC", "x_transferred" ], "url": "https://github.com/libuv/libuv/commit/c858a147643de38a09dd4164758ae5b685f2b488" }, { "name": "https://github.com/libuv/libuv/commit/e0327e1d508b8207c9150b6e582f0adf26213c39", "tags": [ "x_refsource_MISC", "x_transferred" ], "url": "https://github.com/libuv/libuv/commit/e0327e1d508b8207c9150b6e582f0adf26213c39" }, { "tags": [ "x_transferred" ], "url": "http://www.openwall.com/lists/oss-security/2024/02/08/2" }, { "tags": [ "x_transferred" ], "url": "http://www.openwall.com/lists/oss-security/2024/02/11/1" }, { "tags": [ "x_transferred" ], "url": "https://lists.debian.org/debian-lts-announce/2024/03/msg00005.html" }, { "tags": [ "x_transferred" ], "url": "http://www.openwall.com/lists/oss-security/2024/03/11/1" }, { "tags": [ "x_transferred" ], "url": "https://security.netapp.com/advisory/ntap-20240605-0008/" }, { "tags": [ "x_transferred" ], "url": "https://gitlab.kitware.com/cmake/cmake/-/issues/26112" } ], "x_generator": { "engine": "ADPogram 0.0.1" } } ] }, "dataVersion": "5.1" }
