Fortra BoKS Manager contains a command injection vulnerability in crlserver. An authenticated user authorized to add CRL URLs through BCC, the WSI REST or SOAP API, or the cacrl command-line interface could cause shell command substitution to be processed by crlserver as root on the BoKS Master. BCC and WSI provide network-accessible administration paths and do not require a local sudo or suexec rule; non-root use of cacrl requires such a rule.
The issue affects deployments that process configured CRL URLs. Exploitation requires an authenticated user who can add a CRL URL through one of the supported administration paths. In BCC, the user requires the CRLS add ABAC right. In WSI, the client requires permission to call addCACRLURL for the target domain and sufficient downstream BCCAS authority, through either the caller's forwarded BoKS session or WSI's configured domain account. These are network-accessible paths and do not require local sudo or suexec access. A non-root user of the cacrl command-line path requires a suitable sudo or suexec rule, which may be narrowly scoped to cacrl. Scheduled CRL import processes the URL automatically; a separately permitted download operation may also trigger processing.
Upgrade to boks-server 8.1.0.24 or boks-server 9.0.0.7, as appropriate for the installed maintenance line.
