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." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "CWE-918: Server-Side Request Forgery (SSRF)", "cweId": "CWE-918" } ] } ] }, "affects": { "vendor": { "vendor_data": [ { "vendor_name": "libuv", "product": { "product_data": [ { "product_name": "libuv", "version": { "version_data": [ { "version_affected": "=", "version_value": ">= 1.45.0, < 1.48.0" } ] } } ] } } ] } }, "references": { "reference_data": [ { "url": "https://github.com/libuv/libuv/security/advisories/GHSA-f74f-cvh7-c6q6", "refsource": "MISC", "name": "https://github.com/libuv/libuv/security/advisories/GHSA-f74f-cvh7-c6q6" }, { "url": "https://github.com/libuv/libuv/commit/0f2d7e784a256b54b2385043438848047bc2a629", "refsource": "MISC", "name": "https://github.com/libuv/libuv/commit/0f2d7e784a256b54b2385043438848047bc2a629" }, { "url": "https://github.com/libuv/libuv/commit/3530bcc30350d4a6ccf35d2f7b33e23292b9de70", "refsource": "MISC", "name": "https://github.com/libuv/libuv/commit/3530bcc30350d4a6ccf35d2f7b33e23292b9de70" }, { "url": "https://github.com/libuv/libuv/commit/c858a147643de38a09dd4164758ae5b685f2b488", "refsource": "MISC", "name": "https://github.com/libuv/libuv/commit/c858a147643de38a09dd4164758ae5b685f2b488" }, { "url": "https://github.com/libuv/libuv/commit/e0327e1d508b8207c9150b6e582f0adf26213c39", "refsource": "MISC", "name": "https://github.com/libuv/libuv/commit/e0327e1d508b8207c9150b6e582f0adf26213c39" }, { "url": "http://www.openwall.com/lists/oss-security/2024/02/08/2", "refsource": "MISC", "name": "http://www.openwall.com/lists/oss-security/2024/02/08/2" }, { "url": "http://www.openwall.com/lists/oss-security/2024/02/11/1", "refsource": "MISC", "name": "http://www.openwall.com/lists/oss-security/2024/02/11/1" }, { "url": "https://lists.debian.org/debian-lts-announce/2024/03/msg00005.html", "refsource": "MISC", "name": "https://lists.debian.org/debian-lts-announce/2024/03/msg00005.html" }, { "url": "http://www.openwall.com/lists/oss-security/2024/03/11/1", "refsource": "MISC", "name": "http://www.openwall.com/lists/oss-security/2024/03/11/1" }, { "url": "https://security.netapp.com/advisory/ntap-20240605-0008/", "refsource": "MISC", "name": "https://security.netapp.com/advisory/ntap-20240605-0008/" }, { "url": "https://gitlab.kitware.com/cmake/cmake/-/issues/26112", "refsource": "MISC", "name": "https://gitlab.kitware.com/cmake/cmake/-/issues/26112" } ] }, "source": { "advisory": "GHSA-f74f-cvh7-c6q6", "discovery": "UNKNOWN" }, "impact": { "cvss": [ { "attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "LOW", "baseScore": 7.3, "baseSeverity": "HIGH", "confidentialityImpact": "LOW", "integrityImpact": "LOW", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L", "version": "3.1" } ] } }
