Data exposure and alteration via expired-domain reference

Published Apr 21, 2025 · Updated Apr 21, 2025

An expired-domain reference in OpenText ArcSight Enterprise Security Manager allows remote attackers to read or alter data.

Affected releases span 0 through 7.6.6, 7.7.0 through 7.7.1, 7.8.0 through 7.8.1, and 24.1 through 25.1; exploitation requires an unspecified precondition and passive user interaction.
