DescriptionFortra 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.
