CVE-2019-3750 (GCVE-0-2019-3750)

Vulnerability from cvelistv5 – Published: 2019-12-03 20:20 – Updated: 2024-09-16 23:11

Summary

Dell Command Update versions prior to 3.1 contain an Arbitrary File Deletion Vulnerability. A local authenticated malicious user with low privileges potentially could exploit this vulnerability to delete arbitrary files by creating a symlink from the "Temp\IC\ICDebugLog.txt" to any targeted file. This issue occurs because of insecure handling of Temp directory permissions that were set incorrectly.

Severity

5.6 (Medium)
