CVE-2026-79899

Fortra BoKS Manager bccgethostcert insecure temporary file vulnerability

Published Oct 1, 2026 CVSS 3.1 · 7.9 High EPSS < 1% KEV · Not listed
Description
Fortra BoKS Manager contains an insecure temporary file vulnerability in bccgethostcert. The utility creates predictable temporary files without first setting a restrictive umask. A local user on the BoKS Master who can read files under BOKS_tmp may be able to obtain CA secret or host private-key material while the utility runs, or obtain CA secret material left behind after successful certificate creation.

Remediation

Vendor Solution

Upgrade to boks-server 8.1.0.24 or 9.0.0.7.


Vendor Workaround

Until a fixed release is installed, restrict local access to the BoKS Master and BOKS_tmp, invoke bccgethostcert with a restrictive umask such as 077, and securely remove any stale bcccax.* or bcccreds.* files from BOKS_tmp.
