Forticlient

A Denial of service (DoS) vulnerability in FortiClient for Linux 6.2.1 and below may allow an user with low privilege to cause FortiClient processes running under root privilege crashes via sending specially crafted IPC client requests to the fctsched process due the nanomsg not been correctly validated.Show less

A privilege escalation vulnerability in FortiClient for Linux 6.2.1 and below may allow an user with low privilege to run system commands under root privilege via injecting specially crafted "ExportLogs" type IPC client requests to the fctsched process.Show less

An Improper Neutralization of Special Elements used in a Command vulnerability in one of FortiClient for Mac OS root processes, may allow a local user of the system on which FortiClient is running to execute unauthorized code as root by bypassing a security check.Show less

Use of a hardcoded cryptographic key in the FortiGuard services communication protocol may allow a Man in the middle with knowledge of the key to eavesdrop on and modify information (URL/SPAM services in FortiOS 5.6, and URL/SPAM/AV services in FortiOS 6.0.; URL rating in FortiClient) sent and received from Fortiguard severs by decrypting these messages. Affected products include FortiClient for Windows 6.0.6 and below, FortiOS 6.0.7 and below, FortiClient for Mac OS 6.2.1 and below.Show less

A researcher has disclosed several vulnerabilities against FortiClient for Windows version 6.0.5 and below, version 5.6.6, the combination of these vulnerabilities can turn into an exploit chain, which allows a user to gain system privileges on Microsoft Windows.Show less

An Unsafe Search Path vulnerability in FortiClient Online Installer (Windows version before 6.0.6) may allow an unauthenticated, remote attacker with control over the directory in which FortiClientOnlineInstaller.exe resides to execute arbitrary code on the system via uploading malicious .dll files in that directory.Show less

Users' VPN authentication credentials are unsafely encrypted in Fortinet FortiClient for Windows 5.6.0 and below versions, FortiClient for Mac OSX 5.6.0 and below versions and FortiClient SSLVPN Client for Linux 4.4.2335 and below versions, due to the use of a static encryption key and weak encryption algorithms.Show less

An Information Disclosure vulnerability in Fortinet FortiClient for Windows 5.6.0 and below versions, FortiClient for Mac OSX 5.6.0 and below versions and FortiClient SSLVPN Client for Linux 4.4.2334 and below versions allows regular users to see each other's VPN authentication credentials due to improperly secured storage locations.Show less

A privilege escalation in Fortinet FortiClient Windows 5.4.3 and earlier as well as 5.6.0 allows attacker to gain privilege via exploiting the Windows "security alert" dialog thereby popping up when the "VPN before logon" feature is enabled and an untrusted certificate chain.Show less

The (1) mdare64_48.sys, (2) mdare32_48.sys, (3) mdare32_52.sys, (4) mdare64_52.sys, and (5) Fortishield.sys drivers in Fortinet FortiClient before 5.2.4 do not properly restrict access to the API for management of processes and the Windows registry, which allows local users to obtain a privileged handle to a PID and possibly have unspecified other impact, as demonstrated by a 0x2220c8 ioctl call.Show less
