TITLE

Fortinet FortiOS and FortiSwitch of Cookie Parser buffer overflow vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2016-004445

DESCRIPTION

Buffer overflow in the Cookie parser in Fortinet FortiOS 4.x before 4.1.11, 4.2.x before 4.2.13, and 4.3.x before 4.3.9 and FortiSwitch before 3.4.3 allows remote attackers to execute arbitrary code via a crafted HTTP request, aka EGREGIOUSBLUNDER. Fortinet FortiOS and FortiSwitch of Cookie The parser contains a buffer overflow vulnerability. Fortinet FortiGate is a network security platform developed by Fortinet. The platform provides features such as firewall, anti-virus and intrusion prevention (IPS), application control, anti-spam, wireless controller and WAN acceleration. The vulnerability stems from the program not performing correct boundary checks on user-submitted input. An attacker could use this vulnerability to execute arbitrary code in the context of an affected application and may cause a denial of service. Fortinet FortiGate is prone to a buffer-overflow vulnerability because it fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. Failed exploit attempts will result in denial-of-service conditions. The following versions are affected: Fortinet FortiGate 4.3.8 and prior Fortinet FortiGate 4.2.12 and prior Fortinet FortiGate 4.1.10 and prior. Fortinet FortiOS and FortiSwitch are products developed by Fortinet
