A improper neutralization of special elements used in a command ('command injection') in Fortinet FortiExtender version 7.0.1 and below, 4.2.3 and below, 4.1.7 and below allows an authenticated attacker to execute privileged shell commands via CLI commands including special characters

A improper neutralization of special elements used in an os command ('os command injection') in Fortinet FortiExtender 7.0.0 through 7.0.3, 5.3.2, 4.2.4 and below allows attacker to execute unauthorized code or commands via crafted HTTP requests.

An improper limitation of a pathname to a restricted directory ('Path Traversal') vulnerability [CWE-22] in FortiExtender management interface 7.0.0 through 7.0.3, 4.2.0 through 4.2.4, 4.1.1 through 4.1.8, 4.0.0 through 4.0.2, 3.3.0 through 3.3.2, 3.2.1 through 3.2.3, 5.3 all versions may allow an unauthenticated and remote attacker to retrieve arbitrary files from the underlying filesystem via specially crafted web requests.

CVE-2024-6387 A signal handler race condition was found in OpenSSH's server (sshd), where a client does not authenticate within LoginGraceTime seconds (120 by default, 600 in old OpenSSH versions), then sshd's SIGALRM handler is called asynchronously. However, this signal handler calls various functions that are not async-signal-safe, for example, syslog(). This could lead to remote code execution with root privileges.
