CVE-2026-32996 & CVE-2026-32997 — Veeam Backup & Replication KB4852: LPE in Windows Agent, arbitrary file write in Linux appliance
From CTI Daily Brief — 2026-05-29 · published 2026-05-29 · view item permalink →
Veeam shipped KB4852 / Backup & Replication patch version 13.0.2.29 on 2026-05-27. CVE-2026-32996 (CVSS 7.3) is a local privilege escalation in the Veeam Agent for Microsoft Windows component — an attacker with limited system access can elevate to enable arbitrary command execution, security-control disablement or lateral movement; reporter Alibaba via HackerOne. CVE-2026-32997 (CVSS 8.6) is an arbitrary file write in the Veeam Software Appliance (Linux) constrained to authenticated users with the Backup Administrator role; depending on the target path (cron, authorized_keys, library hijack), this is a stepping stone to RCE or persistence. Both affect all version-13 builds before fixed version 13.0.2.29. CERT-FR / ANSSI advisory CERTFR-2026-AVI-0652 corroborates. No exploitation reported; Veeam notes patch-reverse-engineering risk after disclosure. Veeam is the dominant backup platform in EU public-sector on-premise environments — patch the appliance and Windows agent fleet in tandem with backup-administrator least-privilege review.
