CVE-2026-81822

Administrator access via brute-forced MD5 password hashes

Published Sep 8, 2026 · Updated Sep 8, 2026

Weak password hashing in PIMBoards in AVEVA Pipeline Integrity Monitor 2025 SP1 P1 and earlier allows local users to recover app passwords. PIMBoards project files store app-native user password hashes using MD5, enabling offline computational brute-force recovery by anyone with file read access. Recovered credentials can authenticate as a PIMBoards user and, if an administrator password is recovered, grant administrator access.
