poc-proxycommand-vulnerable

安全でない /.ssh/config による RCE ProxyCommand における %h や %p のようなトークンの使用は、SSH を使用したトンネルや接続プロキシで非常に一般的です。 脆弱な設定 root@kitploit: host .example.com ProxyCommand /usr/bin/nc -X connect -x 192.0.2.0:8080 %h %p 注意: 私の初期評価では、'%h' シングルクォート を使用すれば回避できると思っていましたが、次のような場合でも脆弱なままのようです: root@kitploit: url = ssh://'open...

GHSA-6X6C-W9W9-HV4H Infracost: Terraform Cloud and registry token disclosure via unvalidated hostname

Impact Sensitive information exposure in the Infracost Terraform Cloud/Enterprise integration. Several code paths attached a configured secret token to a request whose host was taken straight from the scanned Terraform, with no check that the host was the trusted endpoint. The condition that...

golang.org/x/net/idna: golang: net/http: golang.org/x/net/idna: Privilege escalation via incorrect Punycode label processing

A flaw was found in golang.org/x/net/idna. ToASCII and ToUnicode incorrectly accept Punycode-encoded labels that decode to an ASCII-only hostname for example, xn--example-.com returns example.com instead of an error. Applications that validate the ASCII form then convert to Unicode may grant acce...

CVE-2026-34207

CVE-2026-34207 The SSRF filter checked hostname text, but the actual destination was decided later by DNS. That gap let attacker-controlled Webhook URLs reach loopback, metadata, and private network targets. Intro I found this issue while reviewing Typebot , an open-source chatbot builder, with a...

CVE-2026-86295

A vulnerability was found in D-Link DIR-895L A1102b07. This affects the function sendACK of the file udhcpcd/serverpacket.c of the component udhcpcd. The manipulation of the argument Hostname results in command injection. The attack can be executed remotely. The exploit has been made public and...

io.netty/netty-handler: Netty: TLS hostname verification bypass via OpenSSL client path misconfiguration

A flaw was found in Netty io.netty:netty-handler. When using the SslProvider.OPENSSL client path with a plain X509TrustManager and without Unsafe-based trust-manager wrapping Java 25+, TLS hostname verification is disabled. This misconfiguration allows a man-in-the-middle attacker to present a...

org.apache.httpcomponents.client5/httpclient5: Apache HttpComponents Client: Server impersonation via improper TLS hostname verification

A flaw was found in the asynchronous version of Apache HttpComponents Client. This improper Transport Layer Security TLS hostname verification vulnerability allows a remote attacker to intercept and modify network traffic. By presenting a valid certificate for a different domain, an attacker can...

GHSA-FPH4-WMHF-6FWF fast-uri vulnerable to server-side request forgery via repeated hostname percent-decoding

Impact fast-uri decodes a hostname's percent escapes twice in a single normalize or resolve call: once during parsing and again during authority recomposition. A nested percent-encoded host therefore survives the first decode and is turned into a live destination by the second, so...
