A flaw in the way reply ICMP packets are limited in the Linux kernel functionality was found that allows to quickly scan open UDP ports. This flaw allows an off-path remote user to effectively bypassing source port UDP randomization. The highest threat from this vulnerability is to confidentiality and possibly integrity, because software that relies on UDP source port randomization are indirectly affected as well.

CVE-2021-41773: A flaw was found in a change made to path normalization in Apache HTTP Server 2.4.49. An attacker could use a path traversal attack to map URLs to files outside the directories configured by Alias-like directives. If files outside of these directories are not protected by the usual default configuration "require all denied", these requests can succeed. If CGI scripts are also enabled for these aliased paths, this could allow for remote code execution
Impact to Pexip Infinity: Medium
Affected versions of Pexip Infinity: 26.1
CVSS3.1 base score: 5.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)
Mitigation: Pexip Infinity configures the Apache HTTP server with a strict ACL which denies access unless explicitly granted. Support for CGI scripts is not enabled. The scope of this vulnerability is limited to the disclosure, on the Pexip Infinity Management Node, of the contents of the administrative web interface bootstrap script. This script contains no credentials or other sensitive information. Pexip Infinity Conferencing Nodes will not expose any information as a result of this vulnerability.
As general good practice, ensure that access to the Pexip Infinity Management Node is restricted to trusted networks using appropriate firewalls.
