There is a vulnerability in TrendMicro Antivirus, which allows an attacker to escalate to SYSTEM privilege, Denial of service, or potential execute arbitrary code.
Vulnerable Systems:
* TrendMicro Antivirus prior to PccScan.dll build 1451
While decoding the .uue file., TrendMicro Antivirus will create a .zip file, by manipulating the .uue file, we can make the TrendMicro AV generate a .zip file which contains a long file name.
Due to the incorrect usage of wcsncpy_s() API while PccScan.dll is trying to copy this long file name into a static buffer, the SfCtlCom.exe will crash.
Because SfCtlCom.exe is running under SYSTEM privilege, local privilege is possible in some cases, e.g. there is a just-in-time debugger presented.
And also, According to the vendor: "malformed UUE is not necessary, just a malformed zip file is enough"
So this vulnerability should be called as a ".ZIP processing vulnerability", not .UUE
The vulnerability can be exploited remotely, by sending Email or convince the victim visit attacker controlled website. Or can be exploited locally to gain the SYSTEM privilege.
