https://notcve.org/view.php?id=CVE-2022-20922
Multiple vulnerabilities in the Server Message Block Version 2 (SMB2) processor of the Snort detection engine on multiple Cisco products could allow an unauthenticated, remote attacker to bypass the configured policies or cause a denial of service (DoS) condition on an affected device. These vulnerabilities are due to improper management of system resources when the Snort detection engine is processing SMB2 traffic. An attacker could exploit these vulnerabilities by sending a high rate of certain types of SMB2 packets through an affected device. A successful exploit could allow the attacker to trigger a reload of the Snort process, resulting in a DoS condition. Note: When the snort preserve-connection option is enabled for the Snort detection engine, a successful exploit could also allow the attacker to bypass the configured policies and deliver a malicious payload to the protected network. The snort preserve-connection setting is enabled by default. See the Details ["#details"] section of this advisory for more information. Note: Only products that have Snort 3 configured are affected. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-snort-smb-3nfhJtr • CWE-244: Improper Clearing of Heap Memory Before Release ('Heap Inspection') •
CVSS: 5.4EPSS: 0%CPEs: 1EXPL: 0CVE-2022-20969
https://notcve.org/view.php?id=CVE-2022-20969
A vulnerability in multiple management dashboard pages of Cisco Umbrella could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the Cisco Umbrella dashboard. This vulnerability is due to unsanitized user input. An attacker could exploit this vulnerability by submitting custom JavaScript to the web application and persuading a user of the interface to click a maliciously crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface or access sensitive browser-based information. Una vulnerabilidad en varias páginas del panel de administración de Cisco Umbrella podría permitir que un atacante remoto autenticado lleve a cabo un ataque de cross-site scripting (XSS) contra un usuario del panel de Cisco Umbrella. Esta vulnerabilidad se debe a la entrada de usuario no sanitizada. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-umbrella-xss-LfeYQV3 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVSS: 8.1EPSS: 0%CPEs: 1EXPL: 0CVE-2022-20773 – Cisco Umbrella Virtual Appliance Static SSH Host Key Vulnerability
https://notcve.org/view.php?id=CVE-2022-20773
A vulnerability in the key-based SSH authentication mechanism of Cisco Umbrella Virtual Appliance (VA) could allow an unauthenticated, remote attacker to impersonate a VA. This vulnerability is due to the presence of a static SSH host key. An attacker could exploit this vulnerability by performing a man-in-the-middle attack on an SSH connection to the Umbrella VA. A successful exploit could allow the attacker to learn the administrator credentials, change configurations, or reload the VA. Note: SSH is not enabled by default on the Umbrella VA. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-uva-static-key-6RQTRs4c • CWE-321: Use of Hard-coded Cryptographic Key CWE-798: Use of Hard-coded Credentials •
CVSS: 4.1EPSS: 0%CPEs: 1EXPL: 0CVE-2022-20805 – Cisco Umbrella Secure Web Gateway File Decryption Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2022-20805
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. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-uswg-fdbps-xtTRKpp6 • CWE-327: Use of a Broken or Risky Cryptographic Algorithm CWE-693: Protection Mechanism Failure •
CVSS: 9.8EPSS: 0%CPEs: 1EXPL: 0CVE-2022-20738 – Cisco Umbrella Secure Web Gateway File Inspection Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2022-20738
A vulnerability in the Cisco Umbrella Secure Web Gateway service could allow an unauthenticated, remote attacker to bypass the file inspection feature. This vulnerability is due to insufficient restrictions in the file inspection feature. An attacker could exploit this vulnerability by downloading a crafted payload through specific methods. A successful exploit could allow the attacker to bypass file inspection protections and download a malicious payload. Una vulnerabilidad en el servicio Cisco Umbrella Secure Web Gateway podría permitir a un atacante remoto no autenticado omitir la funcionalidad file inspection. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-swg-fbyps-3z4qT7p • CWE-693: Protection Mechanism Failure •
