CVE-2018-15363

Vulnerability

An out-of-bounds read vulnerability exists in Trend Micro Security 2018 (Consumer) products, specifically in the coreServiceShell.exe process when handling request ID 0x2002 for IDAMSPMASTER. The flaw results from lack of proper validation of user-supplied data, leading to a memory access past the end of an allocated buffer. Affected versions include Trend Micro Maximum Security and other 2018 consumer products as described in the ZDI advisory [1].

Exploitation

An attacker must first obtain the ability to execute low-privileged code on the target system. The attack is local and requires no user interaction beyond gaining initial low-privilege access. The attacker can then send a crafted request to the service process to trigger the out-of-bounds read, potentially leading to code execution [1].

Impact

Successful exploitation allows an attacker to escalate privileges to SYSTEM, enabling full control of the affected system. The attacker can execute arbitrary code with high integrity, leading to complete compromise of confidentiality, integrity, and availability [1].

Mitigation

Trend Micro has released a patch for this vulnerability. Users should update to the latest version of Trend Micro Security 2018. Refer to vendor advisories for specific patched versions [1].
