Summary

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. This manipulation of the argument customCode causes os command injection. It is possible to initiate the attack remotely. 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.

Risk Assessment

A remote attacker can execute arbitrary commands on the server, potentially leading to full system compromise, data theft, or application takeover.

Recommendation

Update CRMEB to the latest version if a patch is available. Restrict access to the admin panel and do not rely on the public exploit.
