Recent Cisco Umbrella Secure Web Gateway Security Vulnerabilities
A vulnerability in the automatic decryption process in Cisco Umbrella Secure Web Gateway (SWG) could
CVE-2022-20805
4.1 - Medium
- April 21, 2022
A vulnerability in the automatic decryption process in Cisco Umbrella Secure Web Gateway (SWG) could allow an authenticated, adjacent attacker to bypass the SSL decryption and content filtering policies on an affected system. This vulnerability is due to how the decryption function uses the TLS Sever Name Indication (SNI) extension of an HTTP request to discover the destination domain and determine if the request needs to be decrypted. An attacker could exploit this vulnerability by sending a crafted request over TLS from a client to an unknown or controlled URL. A successful exploit could allow an attacker to bypass the decryption process of Cisco Umbrella SWG and allow malicious content to be downloaded to a host on a protected network. There are workarounds that address this vulnerability.
Use of a Broken or Risky Cryptographic Algorithm
A vulnerability in the Cisco Umbrella Secure Web Gateway service could
CVE-2022-20738
