Fortinet FortiWeb Multiple Vulnerabilities

Fortinet FortiWeb versions 7.0 through 8.0.2 contain an improper rate-limiting flaw that allows unauthenticated remote attackers to bypass authentication attempt restrictions through crafted requests. This vulnerability enables attackers to conduct brute-force password attacks against FortiWeb instances with reduced constraints, with success dependent on attacker resources and target password complexity. No patch is currently available for affected versions.

A improper neutralization of special elements used in an os command ('os command injection') vulnerability in Fortinet FortiWeb 8.0.0 through 8.0.1, FortiWeb 7.6.0 through 7.6.5, FortiWeb 7.4.0 through 7.4.11, FortiWeb 7.2.0 through 7.2.12, FortiWeb 7.0.0 through 7.0.12 may allow an authenticated attacked to execute arbitrary commands via a specialy crafted HTTP request. [CVSS 7.2 HIGH]

Arbitrary code execution in Fortinet FortiWeb 7.0.2 through 8.0.2 stems from a stack-based buffer overflow triggered by crafted HTTP requests from authenticated attackers who can bypass stack protection mechanisms. The vulnerability affects multiple FortiWeb versions and requires high privileges and specific conditions to exploit, though no patch is currently available. An authenticated attacker with sufficient privileges could leverage this flaw to execute arbitrary commands on affected systems.

A NULL Pointer Dereference vulnerability [CWE-476] vulnerability in Fortinet FortiWeb 8.0.0 through 8.0.2, FortiWeb 7.6.0 through 7.6.6, FortiWeb 7.4 all versions, FortiWeb 7.2 all versions, FortiWeb 7.0 all versions may allow an authenticated attacker to crash the HTTP daemon via crafted HTTP requests. [CVSS 2.7 LOW]
