Trend Micro NSC modules TmPfw.exe security bypass
| nsc-tmpfw-security-bypass (48108) |  Medium Risk |
Description:
Trend Micro Network Security Component (NSC) modules could allow a local attacker to bypass security restrictions, caused by a missing password check in the Trend Micro Personal Firewall service (TmPfw.exe). By sending a specially-crafted packet to TCP port 40000, a local attacker could exploit this vulnerability to bypass security restrictions to modify firewall settings without requiring password authentication.
