CVE-2026-79898— Fortra BoKS Manager crlserver command injection vulnerability

Quick assessment

Affected
Fortra BoKS Manager
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Fortra BoKS Manager 中的 crlserver 组件存在命令注入漏洞。通过 BCC、WSI REST 或 SOAP API，或使用 cacrl 命令行接口获得添加 CRL URL 权限的已认证用户，可诱导 crlserver 在 BoKS Master 上以 root 权限执行 shell 命令替换。BCC 和 WSI 提供可通过网络访问的管理路径，且无需本地 sudo 或 suexec 规则；而非 root 用户使用 cacrl 则需要此类权限配置。

Vulnerability Title
Fortra BoKS Manager crlserver command injection vulnerability
Source: CVE Program / CVE List V5
Vulnerability Description
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.
