Description
A weakness has been identified in ZhongBangKeJi CRMEB up to 6.0.0. Affected by this vulnerability is the function eval of the file /adminapi/system/crontab/save of the component Custom Scheduled Task Feature.

The exploit has been made available to the public and could be used for attacks. Vendor documents this as deliberate debug-only behavior. But isSafePhpCode blacklist offers no real RCE containment.
