CVE-2023-28078CRITICAL 9.1

Dell OS10 Networking Switches running 10.5.2.x and above contain a vulnerability with zeroMQ when VLT is configured. A remote unauthenticated attacker could potentially exploit this vulnerability leading to information disclosure and a possible Denial of Service when a huge number of requests are sent to the switch. This is a high severity vulnerability as it allows an attacker to view sensitive data. Dell recommends customers to upgrade at the earliest opportunity.

CVE-2022-0028HIGH 8.6

A PAN-OS URL filtering policy misconfiguration could allow a network-based attacker to conduct reflected and amplified TCP denial-of-service (RDoS) attacks. The DoS attack would appear to originate from a Palo Alto Networks PA-Series (hardware), VM-Series (virtual) and CN-Series (container) firewall against an attacker-specified target. To be misused by an external attacker, the firewall configuration must have a URL filtering profile with one or more blocked categories assigned to a source zone that has an external facing interface. This configuration is not typical for URL filtering and, if set, is likely unintended by the administrator. If exploited, this issue would not impact the confidentiality, integrity, or availability of our products. However, the resulting denial-of-service (DoS) attack may help obfuscate the identity of the attacker and implicate the firewall as the source of the attack. We have taken prompt action to address this issue in our PAN-OS software. All software updates for this issue are expected to be released no later than the week of August 15, 2022. This issue does not impact Panorama M-Series or Panorama virtual appliances. This issue has been resolved for all Cloud NGFW and Prisma Access customers and no additional action is required from them.
