CVE-2024-48862Network attack vector

File read and overwrite via improper link resolution

Published Nov 22, 2024 · Updated Nov 22, 2024

Link-following in QNAP QuLog Center 1.7.x before 1.7.0.831 and 1.8.x before 1.8.0.888 allows remote attackers to read or overwrite files. QNAP has not disclosed the affected request, file-handling routine, or how attacker-controlled links reach filesystem operations. Network access and passive user interaction are required; successful exploitation redirects file access outside the intended location.
