CVE-2019-1069: Task Scheduler Elevation of Privilege Vulnerability
Noroxi assessment
Priority: This week (action score 63/100)
- CISA has confirmed exploitation in the wild (Mar 15, 2022); it is known to be used in ransomware campaigns. Remediation deadline for US federal agencies: Apr 5, 2022.
- Probability of exploitation in the next 30 days: 6.1% (FIRST EPSS); higher than 93.5% of all records.
- Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- According to the record, no fixed version is available yet.
Don’t wait for the next maintenance window. Until a fix is released, restrict access to the affected component and follow the vendor's advisory.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · CISA KEV · FIRST EPSS
An elevation of privilege vulnerability exists in the way the Task Scheduler Service validates certain file operations. An attacker who successfully exploited the vulnerability could gain elevated privileges on a victim system. To exploit the vulnerability, an attacker would require unprivileged code execution on a victim system. The security update addresses the vulnerability by correctly validating file operations.
