Description
Koha Eval Code Injection Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Koha. Authentication is required to exploit this vulnerability. The specific flaw exists within the web service, which listens on TCP port 8081 by default. The issue results from the lack of proper validation of a user-supplied string before passing it to the eval function. An attacker can leverage this vulnerability to execute code in the context of the service account. Was ZDI-CAN-29165.
