CVE-2022-3358 METASPLOIT HIGH ruby SCANNER
OpenSSL 3.0.0-3.0.5 - NULL Pointer Dereference via Legacy Custom Cipher Handling
OpenSSL supports creating a custom cipher via the legacy EVP_CIPHER_meth_new() function and associated function calls. This function was deprecated in OpenSSL 3.0 and application authors are instead encouraged to use the new provider mechanism in order to implement custom ciphers. OpenSSL versions 3.0.0 to 3.0.5 incorrectly handle legacy custom ciphers passed to the EVP_EncryptInit_ex2(), EVP_DecryptInit_ex2() and EVP_CipherInit_ex2() functions (as well as other similarly named encryption and decryption initialisation functions). Instead of using the custom cipher directly it incorrectly tries to fetch an equivalent cipher from the available providers. An equivalent cipher is found based on the NID passed to EVP_CIPHER_meth_new(). This NID is supposed to represent the unique NID for a given cipher. However it is possible for an application to incorrectly pass NID_undef as this value in the call to EVP_CIPHER_meth_new(). When NID_undef is used in this way the OpenSSL encryption/decryption initialisation function will match the NULL cipher as being equivalent and will fetch this from the available providers. This will succeed if the default provider has been loaded (or if a third party provider has been loaded that offers this cipher). Using the NULL cipher means that the plaintext is emitted as the ciphertext. Applications are only affected by this issue if they call EVP_CIPHER_meth_new() using NID_undef and subsequently use it in a call to an encryption/decryption initialisation function. Applications that only use SSL/TLS are not impacted by this issue. Fixed in OpenSSL 3.0.6 (Affected 3.0.0-3.0.5).

CVE-2011-3389 METASPLOIT ruby SCANNER
SSL - Info Disclosure
The SSL protocol, as used in certain configurations in Microsoft Windows and Microsoft Internet Explorer, Mozilla Firefox, Google Chrome, Opera, and other products, encrypts data by using CBC mode with chained initialization vectors, which allows man-in-the-middle attackers to obtain plaintext HTTP headers via a blockwise chosen-boundary attack (BCBA) on an HTTPS session, in conjunction with JavaScript code that uses (1) the HTML5 WebSocket API, (2) the Java URLConnection API, or (3) the Silverlight WebClient API, aka a "BEAST" attack.
CVE-2013-2566 METASPLOIT MEDIUM ruby SCANNER
Oracle Communications Application Session Controller 3.0.0-3.9.1 - Inadequate Encryption Strength via RC4 Algorithm
The RC4 algorithm, as used in the TLS protocol and SSL protocol, has many single-byte biases, which makes it easier for remote attackers to conduct plaintext-recovery attacks via statistical analysis of ciphertext in a large number of sessions that use the same plaintext.
CVSS 5.9
CVE-2015-4000 METASPLOIT LOW ruby SCANNER
OpenSSL 1.0.1-1.0.1l - Man-in-the-Middle Cipher Downgrade via DHE_EXPORT
The TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHE_EXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHE_EXPORT and then rewriting a ServerHello with DHE_EXPORT replaced by DHE, aka the "Logjam" issue.
CVSS 3.7
CVE-2016-0800 METASPLOIT MEDIUM ruby SCANNER
OpenSSL <1.0.1s, 1.0.2 before 1.0.2g - RCE
The SSLv2 protocol, as used in OpenSSL before 1.0.1s and 1.0.2 before 1.0.2g and other products, requires a server to send a ServerVerify message before establishing that a client possesses certain plaintext RSA data, which makes it easier for remote attackers to decrypt TLS ciphertext data by leveraging a Bleichenbacher RSA padding oracle, aka a "DROWN" attack.
CVSS 5.9
CVE-2014-3566 METASPLOIT LOW ruby SCANNER
SSL/TLS Version Detection
The SSL protocol 3.0, as used in OpenSSL through 1.0.1i and other products, uses nondeterministic CBC padding, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, aka the "POODLE" issue.
CVSS 3.4
CVE-2015-2248 EXPLOITDB text WORKING POC
SonicWALL Remote Access Firmware < 7.5.1.0-38sv - Cross-Site Request Forgery via Bookmark Creation
Cross-site request forgery (CSRF) vulnerability in the user portal in Dell SonicWALL Secure Remote Access (SRA) products with firmware before 7.5.1.0-38sv and 8.x before 8.0.0.1-16sv allows remote attackers to hijack the authentication of users for requests that create bookmarks via a crafted request to cgi-bin/editBookmark.
