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 access of uninitialized pointer (CWE-824) vulnerability in FortiWLC versions 8.6.0, 8.5.3 and earlier may allow a local and authenticated attacker to crash the access point being managed by the controller by executing a crafted CLI command.
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
An Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability [CWE-78] in FortiManager version 7.6.0, version 7.4.4 and below, version 7.2.7 and below, version 7.0.12 and below, version 6.4.14 and below and FortiManager Cloud version 7.4.4 and below, version 7.2.7 to 7.2.1, version 7.0.12 to 7.0.1 may allow an authenticated remote attacker to execute unauthorized code via FGFM crafted requests.
A Cleartext Storage of Sensitive Information vulnerability [CWE-312] in FortiClientWindows 7.4.0 through 7.4.1, 7.2.0 through 7.2.6, 7.0.0 through 7.0.13 and FortiClientLinux 7.4.0 through 7.4.2, 7.2.0 through 7.2.7, 7.0.0 through 7.0.13 may permit a local authenticated user to retrieve VPN password via memory dump, due to JavaScript's garbage collector
A relative path traversal in Fortinet FortiWLM version 8.6.0 through 8.6.5 and 8.5.0 through 8.5.4 allows attacker to execute unauthorized code or commands via specially crafted web requests.
A authentication bypass using an alternate path or channel in Fortinet FortiClientWindows version 7.4.0, versions 7.2.4 through 7.2.0, versions 7.0.12 through 7.0.0, and 6.4.10 through 6.4.0 allows low privilege attacker to execute arbitrary code with high privilege via spoofed named pipe messages.
An improper verification of cryptographic signature vulnerability [CWE-347] in FortiClient MacOS version 7.4.0, version 7.2.4 and below, version 7.0.10 and below, version 6.4.10 and below may allow a local authenticated attacker to swap the installer with a malicious package via a race condition during the installation process.
A untrusted search path in Fortinet FortiClientWindows versions 7.4.0, versions 7.2.4 through 7.2.0, versions 7.0.12 through 7.0.0 allows an attacker to run arbitrary code via DLL hijacking and social engineering.
An exposure of sensitive system information to an unauthorized control sphere vulnerability [CWE-497] in FortiWeb version 7.6.0, version 7.4.3 and below, version 7.2.10 and below, version 7.0.10 and below, version 6.3.23 and below may allow an authenticated attacker to access the encrypted passwords of other administrators via the "Log Access Event" logs page.
