CVE Number – CVE-2019-0885
A vulnerability in the Object Linking and Embedding (OLE) component of Microsoft Windows could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted system.
The vulnerability exists because the affected software performs insufficient validation of user-supplied input. An attacker could exploit the vulnerability by persuading a user to access a link or file that submits malicious input to the affected software. A successful exploit could allow the attacker to execute arbitrary code with the privileges of the user. If the user has elevated privileges, the attacker could compromise the system completely.
Microsoft confirmed the vulnerability and released software updates.
- To exploit this vulnerability, the attacker may use misleading language or instructions to persuade a user to access a link or file that submits malicious input to the affected software.
Microsoft addressed this vulnerability by changing how the affected software validates user input.
