**Name of the Vulnerable Software and Affected Versions** ZNC version 1.0 **Description** The issue allows remote authenticated users to cause a denial of service, resulting in a crash due to a NULL pointer reference. This can be achieved by sending a crafted request to specific pages, including the "editnetwork", "editchan", "addchan", or "delchan" page in the webadmin module. **Recommendations** For ZNC version 1.0, as a temporary workaround, consider restricting access to the webadmin module until a patch is available. Avoid using the affected pages, such as "editnetwork", "editchan", "addchan", or "delchan", in the webadmin module to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.
