Description
This security bulletin contains information about 2 vulnerabilities.
1) Information disclosure (CVE-ID: CVE-2014-3566)
CWE-ID: CWE-327 - Use of a Broken or Risky Cryptographic Algorithm
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:A/U:Green
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to usage of insecure SSLv3 protocol in OpenSSL. A remote attacker can force the current connection between user and server to be downgraded to SSLv3 protocol and then use padding-oracle attack on Cypher-block chaining (CBC) mode to decrypt encrypted communication.
Successful exploitation of the vulnerability may allow an attacker to read encrypted communications in clear text.
Note: The vulnerability is known as POODLE.
2) Forced SSLv3 support (CVE-ID: CVE-2014-3568)
CWE-ID: CWE-749 - Exposed Dangerous Method or Function
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to force SSLv3 usage.
When OpenSSL is configured with "no-ssl3" as a build option, servers could accept and complete a SSL 3.0 handshake, and clients could be configured to send them. A remote attacker can force SSLv3 usage and perfom a variety of attacks against SSLv3 protocol
Successful exploitation of the vulnerability may allow an attacker to obtain potentially sensitive information.
