A heap-based buffer overflow vulnerability in the processing of Link Control Protocol messages in FortiGate versions 5.6.12, 6.0.10, 6.2.4 and 6.4.1 and earlier may allow a remote attacker with valid SSL VPN credentials to crash the SSL VPN daemon by sending a large LCP packet, when tunnel mode is enabled. Arbitrary code execution may be theoretically possible, albeit practically very difficult to achieve in this context

Under non-default configuration, a stack-based buffer overflow in FortiOS version 6.0.10 and below, version 5.6.12 and below may allow a remote attacker authenticated to the SSL VPN to crash the FortiClient NAC daemon (fcnacd) and potentially execute arbitrary code via requesting a large FortiClient file name. We are not aware of proof of concept code successfully achieving the latter.

An execution with unnecessary privileges vulnerability in the VCM engine of FortiClient for Linux versions 6.2.7 and below, version 6.4.0. may allow local users to elevate their privileges to root by creating a malicious script or program on the target machine.

An OS command injection (CWE-78) vulnerability in FortiWAN version 4.5.7 and below Command Line Interface may allow a local, authenticated and unprivileged attacker to escalate their privileges to root via executing a specially-crafted command.An OS command injection (CWE-78) vulnerability in FortiWAN Command Line Interface may allow a local, authenticated and unprivileged attacker to escalate their privileges to root via executing a specially-crafted command.

A relative path traversal vulnerability (CWE-23) in FortiWAN version 4.5.7 and below, 4.4 all versions may allow a remote non-authenticated attacker to delete files on the system by sending a crafted POST request. In particular, deleting specific configuration files will reset the Admin password to its default value.

A null pointer dereference in FortiOS versions 7.4.0 through 7.4.1, 7.2.0 through 7.2.5, 7.0 all versions, 6.4 all versions , 6.2 all versions and 6.0 all versions allows attacker to trigger a denial of service via a crafted http request.

A null pointer dereference in FortiOS versions 7.4.0 through 7.4.1, 7.2.0 through 7.2.5, 7.0 all versions, 6.4 all versions , 6.2 all versions and 6.0 all versions allows attacker to trigger a denial of service via a crafted http request.

Multiple improper neutralization of special elements used in an OS command ('OS Command Injection') vulnerabilities [CWE-78] in Fortinet FortiManager version 7.4.0 through 7.4.2 and before 7.2.5, Fortinet FortiAnalyzer version 7.4.0 through 7.4.2 and before 7.2.5 and Fortinet FortiAnalyzer-BigData before 7.4.0 allows an authenticated privileged attacker to execute unauthorized code or commands via crafted CLI requests.

An improper neutralization of special elements in output used by a downstream component ('Injection') vulnerability [CWE-74] in FortiOS version 7.4.3 and below, version 7.2.8 and below, version 7.0.16 and below; FortiProxy version 7.4.3 and below, version 7.2.9 and below, version 7.0.16 and below; FortiSASE version 24.2.b SSL-VPN web user interface may allow a remote unauthenticated attacker to perform phishing attempts via crafted requests.

An improper limitation of a pathname to a restricted directory ('Path Traversal') vulnerability [CWE-22] in Fortinet FortiAnalyzer versions below 7.4.2, Fortinet FortiManager versions below 7.4.2 and Fortinet FortiAnalyzer-BigData version 7.4.0 and below 7.2.7 allows a privileged attacker with read write administrative privileges to create non-arbitrary files on a chosen directory via crafted CLI requests.

A use of externally-controlled format string vulnerability [CWE-134] in FortiOS version 7.4.1 and below, version 7.2.7 and below, 7.0 all versions, 6.4 all versions command line interface may allow a local privileged attacker with super-admin profile and CLI access to execute arbitrary code or commands via specially crafted requests.

An improper control of generation of code ('code injection') in Fortinet FortiClientLinux version 7.2.0, 7.0.6 through 7.0.10 and 7.0.3 through 7.0.4 allows attacker to execute unauthorized code or commands via tricking a FortiClientLinux user into visiting a malicious website

DHCP routing options can manipulate interface-based VPN traffic

DHCP can add routes to a client’s routing table via the classless static route option (121). VPN-based security solutions that rely on routes to redirect traffic can be forced to leak traffic over the physical interface. An attacker on the same local network can read, disrupt, or possibly modify network traffic that was expected to be protected by the VPN.

A client-side enforcement of server-side security in Fortinet FortiPortal version 6.0.0 through 6.0.14 allows attacker to improper access control via crafted HTTP requests.

An authorization bypass through user-controlled key vulnerability [CWE-639] in Fortinet FortiPortal version 7.0.0 through 7.0.3 allows an authenticated attacker to interact with ressources of other organizations via HTTP or HTTPS requests.

A improper neutralization of special elements used in an sql command ('sql injection') in Fortinet FortiPortal versions 7.0.0 through 7.0.6 and version 7.2.0 allows privileged user to obtain unauthorized information via the report download functionality.

An exposure of sensitive information to an unauthorized actor vulnerability [CWE-200] in FortiWeb version 7.4.0, version 7.2.4 and below, version 7.0.8 and below, 6.3 all versions may allow an authenticated attacker to read password hashes of other administrators via CLI commands.
