Details
CVE-2022-28810 refers to a security vulnerability reported in ManageEngine ADSelfService Plus that could lead to remote command execution when administrators enabled custom scripts for password sync with required providers, and set the passwords to be sent as arguments during the sync process. When performing a password change or reset, an authenticated end-user could exploit this vulnerability by entering a CMD command in the password field, and have it run remotely on the machine the ADSelfService Plus server is installed in.
We have now released ADSelfService Plus build 6122 with the following updates to fix this issue:
- Only VBScript and PowerShell files are allowed for custom script.
- All the script will now be stored strictly in the <Installation Directory> /Scripts folder.
- Newly set passwords are encoded and sent to the script as parameters.
- Passwords are sent as string literals instead of arguments to avoid unauthorized execution of commands.
Impact
An authenticated end-user can execute remote codes on the machine where ADSelfService Plus is installed.
Steps to upgrade
Update your ADSelfService Plus instance to 6122 using the service pack.
Post-upgrade
