CVE-2020-23250

Local information disclosure via weak database hashing

Published Jan 5, 2021 · Updated Aug 4, 2024

Weak hashing in Gigamon GigaVUE-OS 5.4 through 5.9 allows local users with high privileges to disclose internal database data. The public record states only that an internal database hash uses a weak algorithm; Gigamon has not disclosed the algorithm, the hash's purpose, or the access path. Exploitation requires local high-privilege access and is limited to confidentiality loss, with no published integrity or availability impact.
