Multiple Trend Micro products TmComm.sys privilege escalation
| trendmicro-tmcomm-privilege-escalation (32353) |  High Risk |
Description:
Multiple Trend Micro products could allow a local authenticated attacker to gain elevated privileges, caused by insecure permissions set on the TmComm DOS device interface (TmComm.sys). A local attacker could exploit this vulnerability using IOCTLs to execute arbitrary code or possibly overwrite arbitrary memory addresses with kernel level privileges.
