Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. In BIG-IP Versions 16.1.x before 16.1.3.1 and 15.1.x before 15.1.6.1, when an LTM Client or Server SSL profile with TLS 1.3 enabled is configured on a virtual server, along with an iRule that calls HTTP::respond, undisclosed requests can cause the Traffic Management Microkernel (TMM) to terminate. Affected configurations have MBEDTLS_SSL_DTLS_CLIENT_PORT_REUSE enabled and MBEDTLS_SSL_IN_CONTENT_LEN less than a threshold that depends on the configuration: 258 bytes if using mbedtls_ssl_cookie_check, and possibly up to 571 bytes with a custom cookie check function. This can cause a server crash or possibly information disclosure based on error responses. In some configurations, an unauthenticated attacker can send an invalid ClientHello message to a DTLS server that causes a heap-based buffer over-read of up to 255 bytes. A threat actor could use this account to access the system configuration and confidential information (such as SSL keys) via an HTTPS request to the /webapi/ URI on port 443 or 5001.Īn issue was discovered in Mbed TLS before 2.28.1 and 3.x before 3.2.0.
WAPPLES through 6.0 has a hardcoded systemi account. H3C SSL VPN through allows wnm/login/login.json svpnlang cookie XSS. This could allow an unauthenticated remote attacker to bypass the TCP brute force prevention and lead to a denial of service condition for the duration of the attack. In Erlang/OTP before 23.3.4.15, 24.x before 24.3.4.2, and 25.x before 25.0.2, there is a Client Authentication Bypass in certain client-certification situations for SSL, TLS, and DTLS.Īffected devices do not properly handle the renegotiation of SSL/TLS parameters. Furthermore, wolfSSL_clear is part of wolfSSL's compatibility layer and is not enabled by default. Only servers that use wolfSSL_clear instead of the recommended SSL_free SSL_new sequence are affected. Note that this bug is only triggered when resuming sessions using TLS session resumption. If the server reuses the previous session structure (struct WOLFSSL) by calling wolfSSL_clear(WOLFSSL* ssl) on it, the next received Client Hello (that resumes the previous session) crashes the server. This occurs in the second session, which is created through TLS session resumption and reuses the initial struct WOLFSSL. When a TLS 1.3 client connects to a wolfSSL server and SSL_clear is called on its session, the server crashes with a segmentation fault. cyassl_connect_step2 in curl/vtls/cyassl.c has a missing X509_free after SSL_get_peer_certificate, leading to information disclosure.Īn issue was discovered in wolfSSL before 5.5.0. An issue was discovered in Samsung TizenRT through 3.0_GBM (and 3.1_PRE).
