CVE-2023-34131Network attack vector

Information disclosure via unauthenticated restricted pages

Published Jul 13, 2023 · Updated Oct 30, 2024

Information exposure in SonicWall GMS 9.3.2-SP1 and Analytics 2.5.0.4-R7 and earlier allows remote attackers to read device details. Multiple restricted web pages omit authentication checks and return serial numbers, internal IP addresses, and hostnames to unauthenticated requests. A network request alone is sufficient, and the disclosed serial number reduces the complexity of a separate password-reset attack.
