A out-of-bounds write vulnerability [CWE-787] in FortiOS and FortiProxy may allow a remote unauthenticated attacker to execute arbitrary code or command via specially crafted HTTP requests.

Workaround : disable SSL VPN (disable webmode is NOT a valid workaround)

Note: This is potentially being exploited in the wild.

A use of externally-controlled format string in Fortinet FortiOS versions 7.4.0 through 7.4.2, 7.2.0 through 7.2.6, 7.0.0 through 7.0.13, FortiProxy versions 7.4.0 through 7.4.2, 7.2.0 through 7.2.8, 7.0.0 through 7.0.14, FortiPAM versions 1.2.0, 1.1.0 through 1.1.2, 1.0.0 through 1.0.3, FortiSwitchManager versions 7.2.0 through 7.2.3, 7.0.0 through 7.0.3 allows attacker to execute unauthorized code or commands via specially crafted packets.

An authentication bypass using an alternate path or channel [CWE-288] vulnerability in Fortinet FortiOS 6.4.0 through 6.4.15, FortiOS 6.2.0 through 6.2.16, FortiOS 6.0 all versions, FortiPAM 1.2.0, FortiPAM 1.1.0 through 1.1.2, FortiPAM 1.0.0 through 1.0.3, FortiProxy 7.4.0 through 7.4.2, FortiProxy 7.2.0 through 7.2.8, FortiProxy 7.0.0 through 7.0.15, FortiSwitchManager 7.2.0 through 7.2.3, FortiSwitchManager 7.0.0 through 7.0.3 allows an unauthenticated attacker to seize control of a managed device via crafted FGFM requests, if the device is managed by a FortiManager, and if the attacker knows that FortiManager's serial number.

An authorization bypass through user-controlled key vulnerability [CWE-639] in FortiOS and FortiProxy SSLVPN may allow an authenticated attacker to gain access to another user’s bookmark via URL manipulation.
