Cipher Bypass

OpenSSL is vulnerable to cipher bypasses. A malicious user can negotiate and complete an SSLv2 handshake with the server even if the ciphers have been disabled on the server. SSLv2 handshakes are vulnerable to man-in-the-middle attacks...

Information Disclosure

OpenSSL is vulnerable to decryption oracle attacks. A malicious user on the network can use the server as an oracle to determine the SSLv2 master key...

Information Disclosure

OpenSSL is vulnerable to padding oracle attacks. A malicious user can use an SSLv2 server as a Bleichenbacher oracle, allowing the malicious user to decrypt TLS ciphertext data...

Denial Of Service (DoS)

OpenSSL is vulnerable to denial of service attacks. The attacks are due to a flaw in the way OpenSSL does the SSLv2 handshake messages. Therefore, when it has SSLv2 and EXPORT-grade cipher suites enabled, attackers can send malicious SSLv2 CLIENT-MASTER-Key messages to cause server failures...

Juniper Junos Multiple OpenSSL Vulnerabilities (JSA10759) (SWEET32)

According to its self-reported version number, the remote Juniper Junos device is affected by the following vulnerabilities related to OpenSSL : - A flaw exists in the ssl3getkeyexchange function in file s3clnt.c when handling a ServerKeyExchange message for an anonymous DH ciphersuite with the...

sslscan - tests SSL/TLS enabled services to discover supported cipher suites

This is a fork of ioerror's version of sslscan the original readme of which is included below. Changes are as follows: Highlight SSLv2 and SSLv3 ciphers in output. Highlight CBC ciphers on SSLv3 POODLE. Highlight 3DES and RC4 ciphers in output. Highlight PFS+GCM ciphers as good in output. Highlig...

Juniper ScreenOS 6.3.x < 6.3.0r23 Multiple Vulnerabilities in OpenSSL (JSA10759) (DROWN)

The version of Juniper ScreenOS running on the remote host is 6.3.x prior to 6.3.0r23. It is, therefore, affected by multiple vulnerabilities in its bundled version of OpenSSL : - A flaw exists in the SSLv2 implementation, specifically in the getclientmasterkey function within file s2srvr.c, due ...

Internet Bug Bounty: SSLv2 doesn't block disabled ciphers (CVE-2015-3197)

This is a DROWN-related issue that essentially circumvented the instructions on how to disable SSLv2 at the time. Its primary effect was that a lot of servers were vulnerable to DROWN even though they thought they had SSLv2 disabled. It was reported to OpenSSL and fixed in versions 1.0.2f and...

Internet Bug Bounty: Cross-protocol attack on TLS using SSLv2 (DROWN) (CVE-2016-0800)

General DROWN was responsibly disclosed to the OpenSSL team prior to the public disclosure. This OpenSSL blog post, by Viktor Dukhovni and Emilia Käsper, describes the vulnerability: https://www.openssl.org/blog/blog/2016/03/01/an-openssl-users-guide-to-drown/ This is probably a good opportunity ...
