{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/66622?format=json","vulnerability_id":"VCID-jhx8-w919-akbp","summary":"Erlang/OTP is a set of libraries for the Erlang programming language. Prior to versions OTP-27.3.3, OTP-26.2.5.11, and OTP-25.3.2.20, a SSH server may allow an attacker to perform unauthenticated remote code execution (RCE). By exploiting a flaw in SSH protocol message handling, a malicious actor could gain unauthorized access to affected systems and execute arbitrary commands without valid credentials. This issue is patched in versions OTP-27.3.3, OTP-26.2.5.11, and OTP-25.3.2.20. A temporary workaround involves disabling the SSH server or to prevent access via firewall rules.","aliases":[{"alias":"CVE-2025-32433"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/496232?format=json","purl":"pkg:apk/alpine/erlang@26.2.5.11-r0?arch=aarch64&distroversion=v3.21&reponame=community","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:apk/alpine/erlang@26.2.5.11-r0%3Farch=aarch64&distroversion=v3.21&reponame=community"},{"url":"http://public2.vulnerablecode.io/api/packages/496233?format=json","purl":"pkg:apk/alpine/erlang@26.2.5.11-r0?arch=armhf&distroversion=v3.21&reponame=community","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:apk/alpine/erlang@26.2.5.11-r0%3Farch=armhf&distroversion=v3.21&reponame=community"},{"url":"http://public2.vulnerablecode.io/api/packages/496234?format=json","purl":"pkg:apk/alpine/erlang@26.2.5.11-r0?arch=armv7&distroversion=v3.21&reponame=community","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:apk/alpine/erlang@26.2.5.11-r0%3Farch=armv7&distroversion=v3.21&reponame=community"},{"url":"http://public2.vulnerablecode.io/api/packages/496235?format=json","purl":"pkg:apk/alpine/erlang@26.2.5.11-r0?arch=loongarch64&distroversion=v3.21&reponame=community","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:apk/alpine/erlang@26.2.5.11-r0%3Farch=loongarch64&distroversion=v3.21&reponame=community"},{"url":"http://public2.vulnerablecode.io/api/packages/496236?format=json","purl":"pkg:apk/alpine/erlang@26.2.5.11-r0?arch=ppc64le&distroversion=v3.21&reponame=community","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:apk/alpine/erlang@26.2.5.11-r0%3Farch=ppc64le&distroversion=v3.21&reponame=community"},{"url":"http://public2.vulnerablecode.io/api/packages/496237?format=json","purl":"pkg:apk/alpine/erlang@26.2.5.11-r0?arch=riscv64&distroversion=v3.21&reponame=community","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:apk/alpine/erlang@26.2.5.11-r0%3Farch=riscv64&distroversion=v3.21&reponame=community"},{"url":"http://public2.vulnerablecode.io/api/packages/496238?format=json","purl":"pkg:apk/alpine/erlang@26.2.5.11-r0?arch=s390x&distroversion=v3.21&reponame=community","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:apk/alpine/erlang@26.2.5.11-r0%3Farch=s390x&distroversion=v3.21&reponame=community"},{"url":"http://public2.vulnerablecode.io/api/packages/496239?format=json","purl":"pkg:apk/alpine/erlang@26.2.5.11-r0?arch=x86&distroversion=v3.21&reponame=community","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:apk/alpine/erlang@26.2.5.11-r0%3Farch=x86&distroversion=v3.21&reponame=community"},{"url":"http://public2.vulnerablecode.io/api/packages/496240?format=json","purl":"pkg:apk/alpine/erlang@26.2.5.11-r0?arch=x86_64&distroversion=v3.21&reponame=community","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:apk/alpine/erlang@26.2.5.11-r0%3Farch=x86_64&distroversion=v3.21&reponame=community"},{"url":"http://public2.vulnerablecode.io/api/packages/93543?format=json","purl":"pkg:deb/debian/erlang@1:23.2.6%2Bdfsg-1%2Bdeb11u1?distro=trixie","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-2uh8-nhph-gfb6"},{"vulnerability":"VCID-883b-48uw-6yag"},{"vulnerability":"VCID-b3hg-mjga-nbg1"},{"vulnerability":"VCID-dazh-ypb5-akfp"},{"vulnerability":"VCID-dccw-cx8r-r7a1"},{"vulnerability":"VCID-ryy7-f45d-yyhv"},{"vulnerability":"VCID-wsby-unw4-zqe7"},{"vulnerability":"VCID-yyfx-f783-fqgk"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/erlang@1:23.2.6%252Bdfsg-1%252Bdeb11u1%3Fdistro=trixie"},{"url":"http://public2.vulnerablecode.io/api/packages/93560?format=json","purl":"pkg:deb/debian/erlang@1:23.2.6%2Bdfsg-1%2Bdeb11u2?distro=trixie","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/erlang@1:23.2.6%252Bdfsg-1%252Bdeb11u2%3Fdistro=trixie"},{"url":"http://public2.vulnerablecode.io/api/packages/93559?format=json","purl":"pkg:deb/debian/erlang@1:25.2.3%2Bdfsg-1%2Bdeb12u1?distro=trixie","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/erlang@1:25.2.3%252Bdfsg-1%252Bdeb12u1%3Fdistro=trixie"},{"url":"http://public2.vulnerablecode.io/api/packages/93541?format=json","purl":"pkg:deb/debian/erlang@1:25.2.3%2Bdfsg-1%2Bdeb12u4?distro=trixie","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-2uh8-nhph-gfb6"},{"vulnerability":"VCID-883b-48uw-6
