Detection & IOCsextracted from sources · hover to see the quote
- →Exploitation requires local logon and execution of a specially crafted application; monitor for unusual user-mode processes attempting to read kernel memory. ↗
- →The vulnerability enables unintentional read access to kernel-space memory from a user-mode process; detection should focus on anomalous kernel object access patterns from user-mode. ↗
- ·Exploitation is rated 'Exploitation More Likely' for both latest and older software releases, but as of advisory publication it had not been publicly disclosed or actively exploited. ↗
- ·The vulnerability does not allow direct code execution or privilege escalation; it is an information disclosure primitive likely used as a stepping stone in a broader attack chain. ↗

CVE-2018-8477 [MEDIUM] Windows Kernel Information Disclosure Vulnerability
Windows Kernel Information Disclosure Vulnerability
Description: An information disclosure vulnerability exists when the Windows kernel improperly handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the user’s system.
To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The vulnerability would not allow an attacker to execute code or to elevate user rights directly, but it could be used to obtain information that could be used to try to further compromise the affected system.
The update addresses the vulnerability by correcting how the Windows kernel handles objects in memory.
