Cisco Web Security Appliance (WSA) Server Name Identification Data Exfiltration (cisco-sa-sni-data-exfil-mFgzXqLN)
According to its self-reported version, Cisco Web Security Appliance WSA is affected by a vulnerability in Server Name Identification SNI request filtering that allows an unauthenticated, remote attacker to bypass filtering technology on an affected device and exfiltrate data from a compromised...
CVE-2021-34433
In Eclipse Californium version 2.0.0 to 2.6.4 and 3.0.0-M1 to 3.0.0-M3, the certificate based x509 and RPK DTLS handshakes accidentally succeeds without verifying the server side's signature on the client side, if that signature is not included in the server's ServerKeyExchange...
CVE-2021-34433
The CVE concerns Eclipse Californium where certificate-based DTLS handshakes (X.509 and RPK) can accidentally succeed without verifying the client-side signature on the server, if the signature is not included in the server’s ServerKeyExchange. Affected versions are 2.0.0–2.6.4 and 3.0.0-M1–3.0.0...
The vulnerability of the Server Name Identification (SNI) component of the Cisco Web Security Appliance internet server, the micro-programming software for Cisco Firepower Threat Defense network firewalls, and the intrusion detection systems allows a malicious actor to gain full control over the compromised host and unauthorized access to protected information.
The vulnerability of the Server Name Identification SNI component of the Cisco Web Security Appliance internet server, as well as the micro-programming software for Cisco Firepower Threat Defense and the intrusion detection system Snort, is related to SSL handshake filtering errors. Exploiting th...
CVE-2021-38459
The data of a network capture of the initial handshake phase can be used to authenticate at a SYSDBA level. If a specific .exe is not restarted often, it is possible to access the needed handshake packets between admin/client connections. Using the SYSDBA permission, an attacker can change user...

CVE-2020-29548
An issue was discovered in SmarterTools SmarterMail through 100.0.7537. Meddler-in-the-middle attackers can pipeline commands after a POP3 STLS command, injecting plaintext commands into an encrypted user session...
libcurl-using applications can ask for a specific client certificate to be used in a transfer. This is done with the `CURLOPT_SSLCERT` option (`--cert` with the command line tool).When libcurl is built to use the macOS native TLS library Secure Transport an application can ask for the client certificate by name or with a file name - using the same option. If the name exists as a file it will be used instead of by name.If the appliction runs with a current working directory that is writable by other users (like `/tmp`) a malicious user can create a file name with the same name as the app wants to use by name and thereby trick the application to use the file based cert instead of the one referred to by name making libcurl send the wrong client certificate in the TLS connection handshake.
